what is the absolute magnitude of the rate of change for [nh₃] if the rate of change for [h₂] is 4.10 m/s in the reaction 2 nh₃(g) → n₂(g) 3 h₂(g)?

Answers

Answer 1

The absolute magnitude of the rate of change for [NH₃] in the reaction 2 NH₃(g) → N₂(g) + 3 H₂(g) when the rate of change for [H₂] is 4.10 M/s is 2.73 M/s.

The absolute magnitude of the rate of change for [NH₃] when the rate of change for [H₂] is 4.10 M/s in the reaction 2 NH₃(g) → N₂(g) + 3 H₂(g) can be calculated using the following steps:

Step 1: Write down the balanced chemical equation:
2 NH₃(g) → N₂(g) + 3 H₂(g)

Step 2: Determine the stoichiometric relationship between NH₃ and H₂:
From the balanced equation, we can see that 2 moles of NH₃ are involved in producing 3 moles of H₂. This means the stoichiometric ratio between NH₃ and H₂ is 2:3.


Step 3: Calculate the rate of change for [NH₃]:
We are given the rate of change for [H₂] which is 4.10 M/s. Using the stoichiometric relationship (2:3) between NH₃ and H₂, we can determine the rate of change for [NH₃]:

Rate of change for [NH₃] = (Rate of change for [H₂]) * (Stoichiometric ratio between NH₃ and H₂)

Rate of change for [NH₃] = (4.10 M/s) * (2 moles NH₃ / 3 moles H₂)

Rate of change for [NH₃] = 2.73 M/s


Step 4: Calculate the absolute magnitude of the rate of change for [NH₃]:
Since the reaction involves the decomposition of NH₃, the rate of change for [NH₃] will be negative. However, we want the absolute magnitude of the rate of change, so we need to disregard the negative sign:

Absolute magnitude of the rate of change for [NH₃] = |-2.73 M/s| = 2.73 M/s

Thus, the absolute magnitude of the rate of change for [NH₃] in the reaction 2 NH₃(g) → N₂(g) + 3 H₂(g) when the rate of change for [H₂] is 4.10 M/s is 2.73 M/s.

determine the specific heat capacity in j/g°c of an alloy that requires 49.1 kj to raise the temperature of 180.7 g alloy from 217 k to 489 k.

Answers

The specific heat capacity of the alloy that requires 49.1 kj to raise the temperature of 180.7 g alloy from 217 k to 489 k is approximately 0.815 J/g°C.

Using the formula below, we can calculate the alloy's specific heat capacity (c) in joules per gram per degree Celsius (J/g°C):

q = mcΔT

Where q is the heat energy, m is the mass of the alloy, c is the specific heat capacity of the alloy, and T is the temperature change in degrees Celsius.

provided values

Given that 1 kJ = 1,000 J, q = 49.1 kJ = 49,100 J.

m = 180.7 g

ΔT = 489 K - 217 K = 272 K

We can find c by rearranging the formula:

c = q / (m * ΔT)

replacing the specified values:

c = 49,100 J / (180.7 g * 272 K)

c ≈ 0.815 J/g°C

How many joules are required to heat 15 grams of ice from -200⁰ to 1400⁰ C?

Answers

Answer: A heat energy of 50160 joules are required to heat 15 grams of ice from \(-200^{o}C\) to \(1400^{o}C\).

Explanation:

Given : mass of ice = 15 g

Convert grams into kg as follows,

\(1 g = 0.001 kg\\15 g = 15 g \times \frac{0.001 kg}{1 g}\\= 0.015 kg\)

Initial temperature = \(-200^{o}C\)

Final temperature = \(1400^{o}C\)

Formula used to calculate the amount of heat energy is as follows.

\(q = m \times C \times (T_{2} - T_{1})\)

where,

q = heat energy

m = mass of substance

C = specific heat of substance (ice here has C = \(2090 J/kg ^{o}C\))

\(T_{1}\) = initial temperature

\(T_{2}\) = final temperature

Substitute the values into above formula as follows.

\(q = m \times C \times (T_{2} - T_{1})\\= 0.015 kg \times 2090 J/kg^{o}C \times [1400 - (-200)]^{o}C\\= 50160 J\)

Thus, we can conclude that 50160 joules are required to heat 15 grams of ice from \(-200^{o}C\) to \(1400^{o}C\).

b) 17.7 L
c) 15.4 L
d) 10.8 L

Answers

the final volume of air in the balloon  when the balloon is taken to a depth of 10ft in a swimming pool, where the pressure is 981 torr is 10.8 L. Answer: d) 10.8 L.

We are given the initial volume of air in the balloon, Vi = 14.0 L. The initial pressure, Pi = 760 torr. The final pressure, Pf = 981 torr. The depth of the swimming pool, h = 10 ft. The temperature of the air, T is constant, which means that the gas in the balloon is an ideal gas.

We can use Boyle's law and the pressure difference to find the final volume of air.Boyle's law states that at a constant temperature, the volume of a gas is inversely proportional to its pressure. That is,V_1/P_1 = V_2/P_2where V1 and P1 are the initial volume and pressure, and V2 and P2 are the final volume and pressure.

Rearranging this equation, we getV_2 = V_1 × P_1/P_2= 14.0 L × (760 torr)/(981 torr)= 10.8 L

Therefore, the final volume of air in the balloon is 10.8 L. Answer: d) 10.8 L.

pure toluene (c7h8) has a normal boiling point of 110.60oc. a solution of 7.80 g of anthracene (c14h10), in 100.0 g.toluene has a boiling point of 112.06oc. a. what is the molality of the solution? b. what is the molal boiling point elevation constant for toluene?

Answers

Pure toluene (c7h8) has a normal boiling point of 110.60oc. A solution of 7.80 g of anthracene (c14h10), in 100.0 g. toluene has a boiling point of 112.06oc. The molality of the solution is 0.438 mol/kg. and the molal boiling point elevation constant for Toluene is 3.33 °C/m.

Given that,

Molecular weight of Toluene, C7H8 = 92 g/mol

Molecular weight of Anthracene, C14H10 = 178 g/mol

Boiling point of pure Toluene, Tb° = 110.6°C

Boiling point of Toluene solution containing Anthracene, Tb = 112.06°C

We need to find the molality of the solution and the molal boiling point elevation constant for Toluene.

Molality of the solution:

Molality is defined as the number of moles of solute per kilogram of solvent.

(Here, the solvent is Toluene and the solute is Anthracene.) Number of moles of Anthracene,

n2 = Weight of Anthracene / Molecular weight of Anthracene = 7.80 g / 178 g/mol = 0.0438 moles

Number of kilograms of solvent,

w1 = Weight of Toluene / 1000 = 100.0 g / 1000 = 0.1 kg

Molality of solution, m = n2 / w1 = 0.0438 / 0.1 = 0.438 mol/kg

Therefore, the molality of the solution is 0.438 mol/kg.

Molal boiling point elevation constant for Toluene:

The elevation in the boiling point of the solvent is given by the formula:

ΔTb = Kb . m . i

where Kb is the molal boiling point elevation constant. m is the molality of the solution. i is the van't Hoff factor (which is equal to 1 for non-electrolytes like Anthracene)

ΔTb = Tb - Tb°= 112.06°C - 110.6°C = 1.46°C

We know that m = 0.438 mol/kg

Hence,1.46 = Kb . 0.438 . 1Kb = 3.33 °C/m

Therefore, the molal boiling point elevation constant for Toluene is 3.33 °C/m.

4. What part of the Amino Acid structure is affected by heat? (1 point)

Answers

Heat primarily affects the non-covalent interactions that stabilize the secondary, tertiary, and quaternary structures of proteins, leading to denaturation and loss of their functional conformation.

Heat can affect various aspects of the amino acid structure, including conformational changes and chemical modifications. The specific region affected by heat depends on the temperature and duration of exposure. Here, we will primarily focus on the heat-induced denaturation of proteins, which are composed of amino acids

Protein denaturation occurs when the heat disrupts the weak non-covalent interactions that stabilize the folded structure of the protein. These interactions include hydrogen bonds, ionic bonds, van der Waals forces, and hydrophobic interactions. As the temperature rises, the increased kinetic energy causes these interactions to weaken and eventually break, leading to the unfolding of the protein.

The primary structure of an amino acid, which consists of a central carbon atom (the alpha carbon) bonded to an amino group, a carboxyl group, a hydrogen atom, and a side chain (R-group), is generally not directly affected by heat. The covalent bonds within the amino acid molecule, including the peptide bonds between adjacent amino acids in a protein chain, are relatively stable and require higher temperatures or other harsh conditions to break.

However, the disruption of non-covalent interactions by heat can lead to changes in the secondary, tertiary, and quaternary structures of proteins. The secondary structure, such as alpha helices and beta sheets, are formed by hydrogen bonding between the backbone atoms of the amino acids. Heat can cause these hydrogen bonds to break, leading to the unfolding of the secondary structure.

Additionally, the tertiary structure, which involves the overall three-dimensional folding of a protein, can be affected by heat. The hydrophobic interactions and other non-covalent bonds responsible for stabilizing the folded conformation can be disrupted, resulting in the protein unfolding into a more extended and disordered state.

In summary, heat primarily affects the non-covalent interactions that stabilize the secondary, tertiary, and quaternary structures of proteins, leading to denaturation and loss of their functional conformation. The primary structure of amino acids, which is determined by the covalent bonds, is generally more resistant to the effects of heat.

The extra electron and the electrons already present in zinc repel each other due to their negative charges. So, you have to give some energy to the zinc atom to overcome this repulsion and make it accept the additional electron. Basically, energy input is required to make zinc accept an extra electron because the electron doesn't fit easily and needs some force to be added.

2500 liters of oxygen gas is produced at 1.00 atm of pressure. It is to be compressed and stored in a 20.0 liter cylinder. If temperature is constant, calculate the pressure of the oxygen in the cylinder. O 125 atm O 80.0 atm O 8.00 am O 4.00 atm

Answers

The pressure of the oxygen in the cylinder can be calculated using the ideal gas law PV = nRT. Therefore, the pressure of the oxygen in the cylinder will be 125 atm.

As we know that,

PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant and T is the temperature (assumed constant). We can also use the proportionality relationship between the initial and final pressures and volumes, P1V1 = P2V2.

Given:

V1 = 2500 L

P1 = 1.00 atm

V2 = 20.0 L

We can rearrange the proportionality equation to find P2:

P2 = P1 * V1/V2

So P2 = 1.00 atm * 2500 L / 20.0 L = 125 atm

Therefore, the pressure of the oxygen in the cylinder will be 125 atm.

It is important to note that compressing a gas to such high pressures is not safe and could cause the cylinder to explode. In practice, this process will be done in steps and in controlled conditions.

What is the molality of a solution containing 4. 0 grams


of NaCl dissolved in 3000 grams of water?

Answers

The molality of the solution containing 4. 0 grams of NaCl dissolved in 3000 grams of water is approximately 0.0228 mol/kg.

To calculate the molality of a solution, you can use the formula:

molality = moles of solute / mass of solvent (in kilograms).

In this case, the solute is NaCl, and the solvent is water.

The number of moles of NaCl needs to be calculated:

The atomic mass of Na (sodium) is 22.99 g/mol, and Cl (chlorine) has an atomic mass of 35.45 g/mol. Therefore, the molar mass of NaCl can be determined by adding these two values together: (22.99 + 35.45) g/mol = 58.44 g/mol. The moles of NaCl can be found by dividing the mass by the molar mass: 4.0 g / 58.44 g/mol ≈ 0.0685 moles.

Next, convert the mass of water to kilograms:
- 3000 g = 3.0 kg.

Finally, calculate the molality using the formula:
- molality = 0.0685 moles / 3.0 kg ≈ 0.0228 mol/kg.

Therefore, the molality of the solution is approximately 0.0228 mol/kg.

When sugar dissolves in water, the molecular structure of water surrounds the individual molecules of sugar and pulls them away from each other.Sugar molecules are polar molecules that have both positive and negative charges. Because the water molecule is also a polar molecule, the sugar molecules are attracted to the water molecule's opposite charges. As a result, the sugar molecules dissolve in water, and the mixture becomes a solution.

Answers

DNA base sequence of CCC produces the mRNA codon that codes for r Asp amino acid. The mutation GAC produces the mRNA codon that codes for Glycine (Gly) amino acid. Since their R groups are different, the mutation could cause structural problems in the new Pro protein.

Protein synthesis is affected if the normal base sequence CCC in the DNA template strand is changed to GAC. When the normal base sequence CCC in the DNA template strand is changed to GAC, protein synthesis is affected.

This is because the new DNA template sequence is GAC, which is then transcribed into a messenger RNA (mRNA) sequence with a corresponding GAC codon that codes for Asp amino acid instead of Pro. As a result, the protein sequence changes and a new protein is produced with a different amino acid sequence.

In detail, the normal DNA base sequence CCC codes for Proline (Pro) amino acid. CCC is transcribed into messenger RNA (mRNA) codon GGG that codes for Glycine (Gly) amino acid. If the DNA base sequence CCC is mutated into GAC, the new mRNA codon is GAC, which codes for Aspartic acid (Asp) amino acid instead of Proline (Pro).

This changes the sequence of amino acids in the protein chain, causing structural problems if the substitution of the amino acid affects the folding of the protein. For instance, the substitution of Pro to Asp in the protein sequence might lead to structural problems.

This is because Proline has a unique ring structure that helps the protein maintain a particular shape. The aspartic acid has a carboxyl group, which could cause structural problems in the protein chain. Additionally, the change in the amino acid sequence might affect the protein's biological function and cause an alteration in its physiological properties.
