which equation is set up correctly to determine the volume of a 1.5 mole sample of oxygen gas at 22 C and 100kPa
Murljashka [212]
Under STP condition, the gas has a rule of 22.4 L per mole. And according to the ideal gas law, V1/T1=V2/T2. Under STP, 1.5 mol gas has volume of 33.6 L. So the volume under 22 C is 33.6*295/273=36.3 L.

Salsk061 [2.6K]

Answer:

kp= 3.1 x 10^(-2)

Explanation:

To solve this problem we have to write down the reaction and use the ICE table for pressures:

                                2SO2      +        O2         ⇄              2SO3

Initial                      3.4 atm           1.3 atm                         0 atm

Change                    -2x                    - x                                + 2x

Equilibrium            3.4 - 2x            1.3 -x                          0.52 atm

In order to know the x value:

2x = 0.52

x=(0.52)/2= 0.26

                               2SO2             +          O2              ⇄              2SO3

Equilibrium        3.4 - 0.52                1.3 - 0.26                     0.52 atm

Equilibrium        2.88 atm                 1.04 atm                      0.52 atm

with the partial pressure in the equilibrium, we can obtain Kp.

Kp=\frac{PSO3^2}{PSO2^2 PO2}=\frac{(0.52)^2}{(2.88)^2(1.04)}=0.03135

A 1-g sample of the compound hydrogen chloride was analyzed and found to be 2.74 percent hydrogen and 97.3 percent chlorine. Wha
inna [77]

Answer:

2.74 percent hydrogen and 97.3 percent chlorine are in 2 g of compound.

The same as initial

Explanation:

HCl → H⁺ + Cl⁻

2.74% H means that in 100 g of compund, 2.74 grams are H

97.3 % Cl means that in 100 g of compound, 97.3 grams are Cl

So how many grams of H and Cl, are in 1 g of compound

100 g ___ 2.74 g are H _____ 97.3 g are Cl

1g _____ 2.74/100 ____ 97.3/100

0.0274 g are H

0.973 g are Cl

In 2 grams we will find

0.0274 g .2 = 0.0548 g of H

0.973 g .2 = 1.946 g of Cl

(grams / total grams) . 100 = %

(0.0548/2 ) .100 = 2.74%

(1.946 /2) .100 = 97.3%

A gas storage tank has a volume of 15 L when the temperature is 115 C and the pressure is 114 kPa. What is the new volume of the
Evgesh-ka [11]

<u>Answer:</u> The new volume of the tank is 4.67 L

<u>Explanation:</u>

To calculate the volume when temperature and pressure has changed, we use the equation given by combined gas law.

The equation follows:

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

where,

P_1,V_1\text{ and }T_1 are the initial pressure, volume and temperature of the gas

P_2,V_2\text{ and }T_2 are the final pressure, volume and temperature of the gas

We are given:

P_1=114kPa\\V_1=15L\\T_1=115^oC=[115+273]K=388K\\P_2=250kPa\\V_2=?\\T_2=-8^oC=[-8+273]K=265K  

Putting values in above equation, we get:  

\frac{114kPa\times 15L}{388K}=\frac{250kPa\times V_2}{265K}\\\\V_2=\frac{114\times 15\times 265}{388\times 250}=4.67L

Hence, the new volume of the tank is 4.67 L
