A mixture of He
aksik [14]

Answer : The partial pressure of nitrogen gas in the mixture is, 9.88 atm

Explanation :

According to the Dalton's Law, the total pressure of the gas is equal to the sum of the partial pressure of individual gases.

Formula used :

p_T=p_{He}+p_{Ar}+p_{N_2}

where,

p_T = total pressure of gas  = 13.6 atm

p_{He} = partial pressure of helium gas  = 1831 torr =  2.41 atm

p_{Ar} = partial pressure of argon gas  = 997 torr =  1.31 atm

Conversion used: (1 atm = 760 torr)

p_{N_2} = partial pressure of nitrogen gas  = ?

Now put all the given values in the above formula, we get:

13.6=2.41+1.31+p_{N_2}

p_{N_2}=9.88atm

Thus, the partial pressure of nitrogen gas in the mixture is, 9.88 atm

If 18.0 g of CO2 is produced in the reaction of C2H2 with O2 to form CO2 and
Tanya [424]

Answer:

3.68 g

Explanation:

n_{CO2} = 18 ÷ 44 = 0.4

2C2H2 + 5O2 → 4CO2 + 2H2O

   2       :    5      :    4      :    2  

                             0.409                 (moles)

⇒ n_{H2O} = 0.409 × 2 ÷ 4 = 0.2045 moles

⇒ m_{H2O} = 0.2045 × 18 = 3.68 grams
