A typical neon light contains neon gas mixed with argon gas.  If the total pressure of the mixture is 1.63 atm and the partial pressure of the neon is 0.71
atm.  What is the partial pressure (atm) of argon?

Answers

the partial pressure of argon is:

1.63-0.71=  0.92 atm


1.63 atm - 0.71 atm = 0.92 atm

Given the balanced equation:2C + 3H2==> C2H6
What is the total number of moles of C that must completely react to produce 2.0 moles of C2H6?
(1) 1.0 mol (3) 3.0 mol
(2) 2.0 mol (4) 4.0 mol

Answers

Answer: The correct answer is option 4.

Explanation:

2C+3H_2\rightarrow C_2H_6

According to the reaction, 1 mol of C_2H_6 is obtained from 2 moles of C gives

Then, 2 moles of C_2H_6 will be obtained from:

(2)/(1)* 2 moles of C =4 moles

Hence, the correct answer is option 4.

The answer is (4) 4.0 mol. This is a stoichiometry problem. You start with 2.0 mol of C2H6 and obtain the moles of C by multiplying 2.0 by the mole ratio, in this case 2. 2.0*2=4.0mol.

To identify a diatomic gas (X2), a researcher carried out the following experiment: She weighed an empty 4.4-L bulb, then filled it with the gas at 1.00 atm and 22.0 ∘C and weighed it again. The difference in mass was 5.1 g . Identify the gas.

Answers

Answer : The diatomic gas is nitrogen gas, N₂.

Explanation :

First we have to calculate the moles of gas.

Using ideal gas equation:

PV=nRT

where,

P = Pressure of gas = 1.00 atm

V = Volume of gas = 4.4 L

n = number of moles of gas = ?

R = Gas constant = 0.0821L.atm/mol.K

T = Temperature of gas = 22.0^oC=273+22.0=295.0K

Putting values in above equation, we get:

1.00atm* 4.4L=n* (0.0821L.atm/mol.K)* 295.0K

n=0.1817mol

Now we have to calculate the molar mass of gas.

\text{Molar mass of gas}=\frac{\text{Given mass of gas}}{\text{Moles of gas}}

\text{Molar mass of gas}=(5.1g)/(0.1817mol)=28.07g/mol

As we are given that the gas is diatomic X₂.

As, 2 atoms of gas X has mass = 28.07 g/mol

So, 1 atom of gas will have mass = (28.07)/(2)=14.04g/mol

From this we conclude that the nitrogen atom has mass of 14.04 g/mol.

Thus, the diatomic gas is nitrogen gas, N₂.
