Explanation:

In a chemical reaction , the reactants are written on the left hand side followed by a rightarrow and then products are given on the right side of the arrow.

Reactants are iron (Fe) and oxygen \((O_2)\) and product is iron oxide \((Fe_2O_3)\).

If 0.01 mol of neon gas at a particular temperature and pressure occupies a volume of 0.225 L, then 0.05 mol of neon gas would occupy a volume of 1.125 L under the same conditions.

Given:

Number of moles of neon gas (n₁) = 0.01 mol

Volume of neon gas (V₁) = 0.225 L

We are required to find the volume of neon gas (V₂) when the number of moles (n₂) is 0.05 mol under the same conditions.

The relationship between the number of moles, volume, and pressure of a gas is given by the ideal gas law: 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.

Since the temperature and pressure are the same in this case, we can rearrange the ideal gas law equation to solve for the volume:

V = (n₁ * V₁) / n₂

Substituting the given values into the equation:

V₂ = (0.01 mol * 0.225 L) / 0.05 mol

V₂ = 0.00225 L / 0.05 mol

V₂ = 0.045 L/mol

Therefore, 0.05 mol of neon gas would occupy a volume of 1.125 L under the same conditions.

The elasticity coefficient for an enzyme in the multistep pathway will depends on the concentration of the enzyme itself and the amounts of the substrate molecules present at each step. Option D is correct.

The elasticity coefficient is a measure of the sensitivity of the rate of the overall reaction to changes in the concentrations of the individual enzymes or substrates in the pathway. A higher elasticity coefficient indicates that the reaction rate is more sensitive to changes in that particular component.

In a multistep pathway, the elasticity coefficient of each enzyme depends on its own concentration as well as the concentrations of the substrates and products that it interacts with in its particular step of the pathway.

Therefore, both the concentration of the enzyme and the amounts of substrate molecules present at each step can affect the elasticity coefficient of an enzyme in a multistep pathway. The levels of regulatory molecules (option B) may also affect the elasticity coefficient of an enzyme, but this is not the only factor that determines it.

Hence, D. is the correct option.

Answer:160

Explanation:3200/20=160

Answer:

about 160 mph

Explanation:

A. Ammonia is the limiting reactant.

B. Theoretical yield of urea is 215.3 kg.

C. Percent yield for the reaction is 86.0%

D. The mass of the excess carbon dioxide left is approximately 54.1 kg.

a) To identify the limiting reactant, we should compare the amount of products formed from each reactant. The chemical equation for the formation of urea \((NH_2CONH_2)\) by combining ammonia \((NH_3)\) and carbon dioxide \((CO_2)\) is as follows:

\(2 NH_3 + CO_2 - > NH_2CONH_2 + H_2O\)

The stoichiometry of the balanced equation indicates that the ratio of ammonia to urea is 2:1.

We can find the number of moles for each reactant using the following masses:

Moles of ammonia = 122.0 kg / 17.03 g/mol = 7.17 mol

Moles of carbon dioxide = 211.4 kg / 44.01 g/mol = 4.80 mol

It takes 14.34 moles of ammonia to react completely with the available carbon dioxide because the ratio of ammonia to urea is 2:1. But the amount of ammonia we have is less than we need - only 7.17 mol. As a result, ammonia is the limiting reactant.

b. Based on the limiting reactant, it is possible to calculate the theoretical yield of urea. We can use the moles of ammonia, which is the limiting reactant, to calculate the moles of urea:

Moles of urea = 7.17 mol / 2 = 3.58 mol

We can determine the theoretical yield of urea using the molar mass of urea (60.06 g/mol) as a starting point:

Theoretical yield of urea = 3.58 mol * 60.06 g/mol = 215.3 kg

C. The actual yield (185.1 kg) is calculated by dividing it by the theoretical yield (215.3 kg), then multiplying the result by 100%.

Percent yield = (185.1 kg / 215.3 kg) * 100% = 86.0%

D. We can calculate the amount of non-limiting reactant that has not reacted yet to determine the excess reactant. Since ammonia is the limiting reactant, we must determine how much excess carbon dioxide there is:

Moles of excess carbon dioxide = Moles of carbon dioxide initially - Moles of carbon dioxide used

= 4.80 mol - (7.17 mol / 2) = 1.23 mol

We can determine the mass of excess carbon dioxide using the molar mass of carbon dioxide (44.01 g/mol):

Excess carbon dioxide = 1.23 mol * 44.01 g/mol = 54.1 kg

Therefore, the mass of the excess carbon dioxide left is approximately 54.1 kg.

The magnitude of the force acting on the body is 4000 Newtons.

To find the magnitude of the force, we can use Newton's second law of motion, which states that the force applied to an object is equal to the product of its mass and acceleration.

The given information includes the mass of the body (80 kg) and the resulting velocity (10 m/s). However, since the time duration (0.2 seconds) is also provided, we can use it to calculate the acceleration of the body.

The formula to calculate acceleration is:

Acceleration = Change in Velocity / Time

The change in velocity can be calculated by subtracting the initial velocity (which is 0 m/s as the body is at rest) from the final velocity:

Change in Velocity = Final Velocity - Initial Velocity

Change in Velocity = 10 m/s - 0 m/s

Change in Velocity = 10 m/s

Now, we can calculate the acceleration:

Acceleration = Change in Velocity / Time

Acceleration = 10 m/s / 0.2 s

Acceleration = 50 m/s²

Finally, we can calculate the magnitude of the force using Newton's second law:

Force = Mass x Acceleration

Force = 80 kg x 50 m/s²

Force = 4000 N

Therefore, the magnitude of the force acting on the body is 4000 Newtons.

Increasing the volume of the reaction mixture will have an effect on the system according to Le Chatelier's principle.

In this particular reaction, which represents the combustion of hydrogen sulfide (H2S) with oxygen (O2) to form water (H2O) and sulfur dioxide (SO2), there are a few factors to consider.

By increasing the volume, the pressure in the system decreases. In response to this change, the system will attempt to counteract the decrease in pressure by favoring the side of the reaction with a higher number of moles of gas.

In the given reaction, the reactants (H2S and O2) have a total of 5 moles of gas, while the products (H2O and SO2) have a total of 4 moles of gas. Therefore, the reaction will shift towards the side of the reaction with a higher number of moles of gas, which is the reactant side.

As a result, increasing the volume will shift the equilibrium towards the reactant side, promoting the formation of more H2S and O2, and thus favoring the production of more water and sulfur dioxide.

have a solution of potassium chlorate containing 4g at 67 degrees celsius. how many additional grams of solute must be added to it, to make it saturated

The mass of \(Mg_2P_2O_7\) that will be obtained would be 0.22 grams

The equation of the reaction is as below:

\(2MgNH_4PO_4 -- > Mg_2P_2O_7 + 2NH_3 + H_2O\)

The mole ratio of \(MgNH_4PO_4\) and \(Mg_2P_2O_7\) is 2:1.

2.087 g sample of \(MgNH_4PO_4\) contains 86.52% Ca3(PO4)2.

The actual amount of \(MgNH_4PO_4\) = 2.087 - (0.8652x2.087) = 0.2813 grams

Mole of 0.2813 grams  \(MgNH_4PO_4\) = 0.2813/137.315 = 0.002mol

Equivalent mole of \(Mg_2P_2O_7\) produced = 0.002/2 = 0.001 mol

Mass of 0.001 mol \(Mg_2P_2O_7\) = 0.001 x 222.55 = 0.22 grams

In other words, the mass of \(Mg_2P_2O_7\) that will be obtained from a 2.087 g sample of a rock that contains 86.52% Ca3(PO4)2 would be 0.22 grams.

2.33 grams of hydrogen gas will be produced from the reaction of zinc metal with 85 grams of hydrochloric acid.

To determine the grams of hydrogen gas produced from the reaction of zinc metal with 85 grams of hydrochloric acid, we must first examine the balanced chemical equation for this reaction:
Zn(s) + 2HCl(aq) → ZnCl₂(aq) + H₂(g)
From the equation, we can see that 1 mole of zinc reacts with 2 moles of hydrochloric acid to produce 1 mole of hydrogen gas. Now, we need to convert the given mass of hydrochloric acid into moles.
The molar mass of HCl is approximately 36.5 g/mol. Therefore, we have:
85 g HCl × (1 mol HCl / 36.5 g HCl) ≈ 2.33 mol HCl
Since 2 moles of HCl react with 1 mole of Zn to produce 1 mole of H₂, we can determine the moles of H₂ produced:
2.33 mol HCl × (1 mol H₂ / 2 mol HCl) ≈ 1.165 mol H₂
Lastly, we'll convert the moles of hydrogen gas into grams. The molar mass of H₂ is approximately 2 g/mol:
1.165 mol H₂ × (2 g H₂ / 1 mol H₂) ≈ 2.33 g H₂
Therefore, approximately 2.33 grams of hydrogen gas will be produced from the reaction of zinc metal with 85 grams of hydrochloric acid.

We first verify that the equation is balanced. We have 5 carbons (C), 2 sulfurs (S), and 4 oxygens (O) on each side of the reaction. So the reaction is balanced.

a) Now if we look at the reaction we can see that when 2 moles of SO2 react, 1 mole of CS2 is produced. That is, the ratio is 2 to 1. For each mole of SO2 half as many moles of CS2 will be produced.

So if we have 9.5 moles of SO2 we will have 9.5/2 moles, that is 4.75 moles of CS2.

Answer a) By reacting 9.50 moles of SO2 with an excess of it would be produced 4.75 moles of CS2.

Now, for the following parts of the question, we can apply the ideal gas law. This is because the reaction is in the gas phase and the law applies only to gases.

Where,

P= Pressure at STP = 1 atm

T= Temperature at STP = 273.15K

R= Ideal law constant = 0.08206 (atm L)/(mol K)

V= Volume of the gas

n= Numer of moles

b)We clear n and we replace the known values of SO2 to find the number of moles of SO2 that react.

Now, for each mole of SO2 that reacts we need 5/2 moles of C, that is 0.24x5/2=0.61 moles of C.

We use mass molar of C to calculate the grams.

Mass molar of C=12.01g/mol

Mass of C= Moles of C x Mass Molar

Mass of C= 0.61 mol x 12.01 g/mol = 7.37 g

So, To fully react 5.5 L of SO2 at STP we will need 7.37 g of C.

c)We apply the gas law again but this time we clear the volume.

We also take into account that for each mole of C, 4 moles of CO are produced, so if we have 20 moles of C we will produce 20x4=80 moles of CO.

So, from 20.0 moles of C at STP can be produced 1793.18 liters of CO

The number of the moles of the sodium chloride = molarity × volume

The number of the moles of the sodium chloride = 0.15 × 0.5

The number of the moles of the sodium chloride = 0.075 mol

The molar mass of the sodium chloride = 58.4 g/mol
