2. If I have 7.70 moles of gas at a pressure of 202.6 kPa, and a temperature of 59.0°C, what is the
e-lub [12.9K]

Answer:

V = 0.104 m³

Explanation:

Given that,

Number of moles, n = 7.70 moles

Pressure, P = 202.6 kPa

Temperature, T = 59.0°C = 332 K

We need to find the volume of the container that the gas. We know that the ideal gas law is as follows :

PV=nRT\\\\V=\dfrac{nRT}{P}, R =8.314 m³-Pa/K-mol

Put all the values,

V=\dfrac{7.7\times 8.314\times 332}{202.6 \times 10^3}\\\\V=0.104\ m^3

So, the volume of the container is equal to 0.104 m³.

A gas made up of atoms escapes through a pinhole 0.392 times as fast as Ne gas. Write the chemical formula of the gas.
Hunter-Best [27]

Answer:  The chemical formula of the gas is Xenon.

Explanation:

From Graham's law of effusion rates, the rate of effusion of a gas is inversely proportional to the square root of its molar mass.

\frac{rate_1}{rate_2}=\sqrt{\frac{M_2}{M_1}}

Given: Rate of unknown gas = 0.392\times R_{Ne}  

Putting the values in the formula:

\frac{rate_X}{rate_{Ne}}=\sqrt{\frac{M_{Ne}}{M_X}}

0.392=\sqrt{\frac{20.17}{M_X}}

Squaring both sides:

0.154=\frac{20.17}{M_X}

M_X=131g/mol

As Xenon (Xe) has molar mass of 131g/mol, Thus the chemical formula of the gas is Xenon.

2. How does the way elements are grouped in the periodic table serve as an advantage to scientists?
Goryan [66]
When looking down the groups the elements have an equal number of electrons in the outer shell. This means they react in a similar way making it easier for scientists to use.
