Becca is a forensic technician analyzing the fragments of a window. She sees that there is a hole in the window, and that the outside hole is smaller than the inside hole. What might she deduce from this information?

Answers

The observation of a smaller outside hole than inside leads Becca to infer that an impact from the outside caused the hole, with a larger object striking and passing through the window from the inside.

From the observation that the hole in the window is smaller on the outside than on the inside, Becca, as a forensic technician, might deduce the following:

The hole was caused by an impact from the outside: The smaller outside hole suggests that the force that created the hole originated from the outside and exerted more pressure on the window surface facing inward.

The object causing the hole was larger on the inside: The discrepancy in hole sizes implies that the object that struck the window had a larger size or diameter on the inside, and as it penetrated the glass, it compressed or fragmented the glass, resulting in a larger hole on the inside.

The object may have passed through the window: The difference in hole sizes indicates that the object may have penetrated the window, potentially passing through to the inside. This could suggest a break-in or an incident involving the window being struck from the outside.

Overall, the observation of a smaller outside hole than inside leads Becca to infer that an impact from the outside caused the hole, with a larger object striking and passing through the window from the inside.

how many grams of P3O9 contain 9.67x10^23 atoms of oxygen?​

Answers

Answer:

49.1 g

Explanation:

First we convert 9.67x10²³ atoms of oxygen into moles, using Avogadro's number:

9.67x10²³ atoms ÷ 6.023x10²³ atoms/mol = 1.60 mol O

Then we calculate how many P₃O₉ moles there would be with 1.60 O moles:

1.60 mol O * \(\frac{1molP_3O_9}{9molO}\) = 0.18 mol P₃O₉

Finally we convert 0.18 P₃O₉ moles into grams, using its molar mass:

0.18 mol P₃O₉ * 237 g/mol = 49.1 g

calculate the modaliti of 2.89 of NaCI dissolved in 0.159 L of water (Given Density of water is 1.00 g/mol)

Answers

Answer:

[NaCl] = 0.31 m

Explanation:

Molality is a sort of solute's concentration, that indicates the moles of solute contained in 1kg of solvent.

In this problem:

solute → NaCl

solvent → H₂O

We need the mass of solvent in kg and we have the volume, so let's convert the volume to mass by the use of density.

1 g/mL = mass / 159 mL

(Notice we needed to convert the volume from L to mL)

159 g is the mass of water. We convert to kg

159 g . 1 kg/1000 g = 0.159 kg

We convert the mass of solute to moles → 2.89 g . 1mol/ 58.45 g = 0.049 moles of NaCl

Molality → mol/kg → 0.049 mol /0.159 kg = 0.31 m

A 0.700L sample of gas at STP is compressed to a volume of 0.200L and the temperature is increased to 30 degrees Celcius . What is the new pressure of the gas (in atm)?

Answers

Answer: the pressure of the gas after the compression is 3.88 atm

Explanation:

The question requires us to calculate the new pressure of a gas, given its initial volume at STP, new volume after compression and temperature after compression.

The following information was provided by the question:

Initial volume = V1 = 0.700 L

Final volume = V2 = 0.200 L

Final temperature = T2 = 30 °C = 303.15 K

To solve this problem, we can apply the equation for ideal gases (shown below) considering the conditions after the compression:

\(P\times V=n\times R\times T\rightarrow P_2=\frac{R\times n\times T_2}{V_2}\)

where R is the constant of gases (R = 0.082057 L.atm/K.mol), n is the number of moles of gas, T2 is the temperature after compression and V2 is the volume after compression.

Note that the number of moles of gas remains the same even after compression. Thus, we can calculate this number of moles considering the inital volume at STP, knowing that 1 mol of a gas at Standard Temperature and Pressure corresponds to 22.4 L of this gas:

22.4 L ------------------------- 1 mol

0.700 L ----------------------- x

Solving for x, we'll have:

\(x=\frac{(0.700L)\times(1mol)}{(22.4L)}=0.0312mol\)

Therefore, the number of moles before and after compression is 0.0312 mol.

Now that we have the values for n, T2 and V2, we can calculate the pressure after compression (P2):

\(\begin{gathered} \begin{equation*} P_2=\frac{R\times n\times T_2}{V_2} \end{equation*} \\ P_2=\frac{(0.082057L.atm/K.mol)\times(0.0312mol)\times(30+273.15)K}{(0.200L)}=3.88atm \end{gathered}\)

Therefore, the pressure of the gas after the compression is 3.88 atm.

Calcium nitrate- make an evidence based argument for why acid rain would cause the calcium carbonate in the marble to slowly break down and wash away over time when calcium nitrate is produced

Answers

Following are the effects of acid rain.

What is Acid Rain?

Acid rain is caused by the accumulation of nitric and sulfuric acids in the atmosphere. These compounds are strong acids and are very soluble in water, dissolving in droplets in clouds.

Limestone effect:

Calcium carbonate, [Ca][CO3], is a very common mineral. A limestone is a well-known form of calcium carbonate. The acid contained in acid rain reacts with carbonate ions and promotes the dissolution of calcium carbonate.

This will create a bicarbonate solution. The presence of limestone and other calcium carbonates in lakes and streams helps maintain a constant pH as the mineral reacts with excess acidity. However, acid rain can eventually exceed the buffering capacity of surface waters.

How does acid rain affect buildings made of marble and limestone?

It is mainly affected in 2 ways: dissolution and alteration. Calcite dissolves when sulfuric, sulfuric and nitric acids in polluted air react with calcite in marble and limestone. Exposed areas of buildings and statues show rough surfaces, worn materials, and loss of sculptural detail. Stoneface material can be lost anywhere or only in more reactive areas.

Hence, this is how acid rain affects.

The complex ion Cu(NH3)42+ is formed in a solution made of 0.0200 M Cu(NO3)2 and 0.300 M NH3. What are the concentrations of Cu2+, NH3, and Cu(NH3)42+ at equilibrium? The formation constant*, Kf, of Cu(NH3)42+ is 1.70 × 1013.

Answers

The concentrations  Cu(NH3)42+ at equilibrium is  [Cu(NH3)42+] = 1.70 × 1013 * (0.0200M) * (0.300M)^4.

The concentrations  of Cu2+ is [Cu(NH3)42+] + [Cu2+]

The concentrations  of NH3 is 4[Cu(NH3)42+] + 4[NH3]

What is concentration equilibrium?

Equilibrium concentration is described as a state when the rate of forward reaction in a chemical reaction becomes equal to the rate of backward reaction.

The equilibrium constant expression for the formation of the complex ion Cu(NH3)42+ is:

Kf = [Cu(NH3)42+] / [Cu2+] * [NH3]^4

where [Cu(NH3)42+], [Cu2+], and [NH3] are the molar concentrations at equilibrium.

The initial concentrations of Cu2+ and NH3 are 0.0200 M and 0.300 M respectively.

We have that Kf = 1.70 × 1013, we then  rearrange the equation to solve for [Cu(NH3)42+]:

1.70 × 1013 = [Cu(NH3)42+] / (0.0200M) * (0.300M)^4

[Cu(NH3)42+] = 1.70 × 1013 * (0.0200M) * (0.300M)^4

Therefore at equilibrium, the concentration of Cu(NH3)42+ is [Cu(NH3)42+] = 1.70 × 1013 * (0.0200M) * (0.300M)^4

A chemist has 3.45 x 1022 molecules of P2O5. How many grams of P2O5 does the chemist have?

Thanks to anyone who helps!

Answers

To convert the number of molecules of P₂O₅ to grams, we need to use the Avogadro's number and the molar mass of P₂O₅ .

How many grams of P₂O₅ does the chemist have according to the question?

The molar mass of P₂O₅ can be calculated as follows:

2 × molar mass of P + 5 × molar mass of O

= 2 × 30.97 g/mol + 5 × 15.99 g/mol

= 61.94 g/mol + 79.95 g/mol

= 141.89 g/mol

Therefore, the molar mass of P₂O₅ is 141.89 g/mol.

Now, we can use Avogadro's number to convert the number of molecules to moles:

3.45 × 10²² molecules / 6.022 × 10²³ molecules/mol

= 0.0573 moles

Finally, we can use the molar mass of P₂O₅ to convert moles to grams:

0.0573 moles × 141.89 g/mol = 8.14 grams

Therefore, the chemist has 8.14 grams of P₂O₅ .

Mass of H2CO3 = 1.05g

Na2CO3 = 2.19
To get the mass, just subtract the mass of one of the product to the reactant.

Mass of H2CO3 = mass of NaHCO3 - mass of Na2CO3

Mass of H2CO3 = 3.24g - 2.19g

Mass of H2CO3 = 1.05g

Mass of H2CO3 = 1.05g

Givens: NaHCO3 = 3.24

Na2CO3 = 2.19

Mass of H2CO3 = mass of NaHCO3 - mass of Na2CO3

Mass of H2CO3 = 3.24g - 2.19g

Mass of H2CO3 = 1.05g

How do you find the mass number?

The number of protons and the number of neutrons combine to determine the mass number of an element. Mass number = proton + neutron. If you want to calculate the number of neutrons an atom has, you can simply subtract the number of protons or atomic numbers from the mass number.

Divide the mass of a substance in grams by the molecular weight. This will give you the number of moles of the substance in a particular mass. For 12 g of water, (25 g) / (18.015 g / mol) = 0.666 mol.

Ag2 CrO4(s)=2Agt (aq) + CrO4²- (aq)
Ag+ (aq) + e- Ag(s)
find the standard reduction potential at 25°C for the half-reaction
Ksp = 1 × 10-12
E = +0.799 V
Ag2 CrO4(s) + 2e¯ 2Ag(s) + CrO4²- (aq)​

Answers

Q = Ksp = 1 × 10^(-12).

Substituting the values into the Nernst equation, we have:

0.799 V = E° - (RT/2F) * ln(1 × 10^(-12))

Now, solving for E°:

E° = 0.799 V + (RT/2F) * ln(1 × 10^(-12))

The value of R is the ideal gas constant, T is the temperature in Kelvin, and F is the Faraday constant.

To find the standard reduction potential at 25°C for the half-reaction Ag2CrO4(s) + 2e¯ → 2Ag(s) + CrO4²-(aq), we can use the Nernst equation, which relates the standard reduction potential (E°) to the equilibrium constant (K) and the reaction quotient (Q).

The Nernst equation is given as follows:

E = E° - (RT/nF) * ln(Q)

Given information:

Ksp = 1 × 10^(-12)

E = +0.799 V (standard reduction potential of Ag+ to Ag)

Since the reaction involves the dissolution of Ag2CrO4(s), the reaction quotient Q can be expressed as [Ag+]²/[CrO4²-].

Since the stoichiometry of the reaction is 2:1 for Ag2CrO4 to Ag+, we can say that [Ag+]² = Ksp.

Therefore, Q = Ksp = 1 × 10^(-12).

Substituting the values into the Nernst equation, we have:

0.799 V = E° - (RT/2F) * ln(1 × 10^(-12))

Now, solving for E°:

E° = 0.799 V + (RT/2F) * ln(1 × 10^(-12))

The value of R is the ideal gas constant, T is the temperature in Kelvin, and F is the Faraday constant.

Please note that without specific values for temperature (T) and the ideal gas constant (R), the exact standard reduction potential at 25°C cannot be determined.

Carbon-14 has a half-life of 5730 years. If an original sample was 100g of C¹4 and it is now 0.781g of C14, how old is your sample?

Answers

Answer:

40,113 years

Explanation:

To find the age of the sample, you need to use the half-life formula:

\(N(t)=N_0(\frac{1}{2})^{t/h\)

In this formula:

------> N(t) = current mass (g)

------> N₀ = initial mass (g)

------> t = time passed (yrs)

------> h = half-life (yrs)

You can plug the given values into the equation and rearrange the formula to find "t".

N(t) = 0.781 g                       t = ? yrs

N₀ = 100 g                           h = 5730 yrs

\(N(t)=N_0(\frac{1}{2})^{t/h\)                                           <----- Half-life formula

\(0.781=100(\frac{1}{2})^{t/5730}\)                                     <----- Insert values

\(0.00781=(\frac{1}{2})^{t/5730}\)                                       <----- Divide both sides by 100

\(log_{1/2}(0.00781)=log_{1/2}((\frac{1}{2})^ {t/5730})\)               <----- Take \(log_{1/2}\) of both sides

\(7.00 = \frac{t}{5730}\)                                                   <----- Solve \(log_{1/2}\)

\(40,113 = t\)                                                   <----- Multiply both sides by 5730

The given sample is 40,113 years .

What do you mean by half-life ?

where,

N(t)=current mass

N₀=initial mass

t=time period
