Explanation:
<u>Answer:</u> The below calculations proves that the rate of diffusion of
is 0.4 % faster than the rate of diffusion of 
<u>Explanation:</u>
To calculate the rate of diffusion of gas, we use Graham's Law.
This law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows the equation:

We are given:
Molar mass of 
Molar mass of 
By taking their ratio, we get:


From the above relation, it is clear that rate of effusion of
is faster than 
Difference in the rate of both the gases, 
To calculate the percentage increase in the rate, we use the equation:

Putting values in above equation, we get:

The above calculations proves that the rate of diffusion of
is 0.4 % faster than the rate of diffusion of 
Answer:
Mass is 725.46g/cm
Explanation:
Mass = density × volume = 22.6g/cm^3 × 32.1cm^2 = 725.46g/cm
Answer:
The molecules of all living things contain backbones that consist of carbon atoms.
Explanation:
Millions of carbon-based compounds make up the cells and other structures of living organisms.
Organisms need these compounds to live, grow, and reproduce. Without them, life could not exist,
