What is the IUPAC name for the compound shown?

66.9 grams of CO₂ ( Carbon dioxide gas ) will be required to exert the given value of pressure at the given volume and temperature.

The Ideal gas law or general gas equation emphasizes on the state or behavior of a hypothetical ideal gas. It states that "the pressure multiplied by volume is equal to moles multiply by the universal gas constant multiply by temperature.

It is expressed as;

PV = nRT

Where P is pressure, V is volume, n is the amount of substance, T is temperature and R is the ideal gas constant ( 0.08206 Latm/molK )

Given the data in the question;

To determine the amount of gas, we substitute our values into the expression above.

PV = nRT

n = PV / RT

n = ( 1.01184atm × 52.3L ) / ( 0.08206Latm/molK × 425K )

n = 52.919232Latm / 34.8755Latm/mol

n = 1.52mol

Now, we the mass of CO₂ ( Carbon dioxide gas ).

Molar mass of CO₂ is 44.01 g/mol

Hence;

1.52mol × 44.01 g/mol = 66.9g

Therefore, 66.9 grams of CO₂ ( Carbon dioxide gas ) will be required to exert the given value of pressure at the given volume and temperature.

From the statement and the information available in the question, the pH of the solution is 12.2.

The term Ka refers to the acid dissociation constant of a substance, we can obtain this by setting up the ICE table as shown;

       C6H5O^-  +   H2O ⇄  C6H5OH + OH^-

I         0.250                           0                0

C         -X                                +X             +X

E      0.250 -x                         x                x

Now;

Kb = 1 * 10^-14/ 1.0 x 10-10

Kb = 1 * 10^-4

Kb = [C6H5OH] [OH^-]/[C6H5O^-]

1 * 10^-4 = x^2/ 0.250 -x

1 * 10^-4 (0.250 -x) = x^2

2.5 * 10^-4 - 1 * 10^-4 x = x^2

x^2 + 1 * 10^-4 x  - 2.5 * 10^-4 = 0

x=0.016 M

Given that; [C6H5OH] = [OH^-] =x

pOH = -log(0.016 M) = 1.8

pH = 14 - 1.8 = 12.2

[tex]\displaystyle \text{pH} = \text{p}K_a + \log \frac{[\text{Base}]}{[\text{Acid}]}[/tex]

For a pH of 5.14 with the given pKa of 4.74, solve for the ratio between acetate and acetic acid:

[tex]\displaystyle \begin{aligned} (5.14) & = (4.74) + \log\frac{[\text{CH$_3$COO$^-$}]}{[\text{CH$_3$COOH}]} \\ \\ \log\frac{[\text{CH$_3$COO$^-$}]}{[\text{CH$_3$COOH}]}& = 0.40 \\ \\ \frac{[\text{CH$_3$COO$^-$}]}{[\text{CH$_3$COOH}]} & = 10^{0.40} \\ \\ & = 2.5\end{aligned}[/tex]

In conclusion, the answer is E.

Answer:

B

Explanation:

From the given chemical equation, we want to determine the mass of arsenic necessary to produce 15.0 mL of 0.0852 M H₂AsO₄⁻.

Find the amount of moles present in 15.0 mL of 0.0852 M H₂AsO₄⁻ solution. Recall that M = mol/L:

[tex]\displaystyle 15.0\text{ mL} \cdot \frac{0.0852\text{ mol H$_2$AsO$_4^-$}}{1\text{ L}} \cdot \frac{1\text{ L}}{1000\text{ mL}} = 0.00128\text{ mol H$_2$AsO$_4^-$}[/tex]

With stoichiometric ratios and molecular weights, determine the mass of arsenic necessary:

[tex]\displaystyle 0.00128 \text{ mol H$_2$AsO$_4^-$} \cdot \frac{8\text{ mol As}}{3\text{ mol H$_2$AsO$_4^-$}}\cdot \frac{74.92\text{ g As}}{1\text{ mol As}} = 0.256\text{ g As}[/tex]

In conclusion, the answer is B.

Answer:

9 gram of H2O can be produced

A 3979 mL flask is occupied by 5.26 g of a gas with a molar mass of 36.02 g/mol at 1.07 atm and 81.7 °C.

An ideal gas is that whose behavior can be explained using the ideal gas laws.

We will use the following expression.

K = °C + 273.15 = 81.7 + 273.15 = 354.9 K

We will use the ideal gas equation.

P × V = n × R × T

n = P × V / R × T

n = 1.07 atm × 3.979 L / (0.08206 atm.L/mol.K) × 354.9 K = 0.146 mol

The molar mass of the gas is 36.02 g/mol.

0.146 mol × 36.02 g/mol = 5.26 g
