<u>Answer:</u> The molar mass of unknown gas is 367.12 g/mol
<u>Explanation:</u>
Rate of a gas is defined as the amount of gas displaced in a given amount of time.

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:

So,

We are given:
Volume of unknown gas (X) = 1.0 L
Volume of oxygen gas = 1.0 L
Time taken by unknown gas (X) = 105 seconds
Time taken by oxygen gas = 31 seconds
Molar mass of oxygen gas = 32 g/mol
Molar mass of unknown gas (X) = ? g/mol
Putting values in above equation, we get:

Hence, the molar mass of unknown gas is 367.12 g/mol
In balancing reactions, it is important to remember that each of the side in the reaction should have the same number of elements. We do as follows:
<span>2SO2(g) + O2(g) -> 2SO3(g)
H2S(g) + 3/2O2(g) -> SO2(g) + H2O(g)
Hope this answers the question. Have a nice day.</span>
I think the correct answer among the choices listed above is option C. The two type of reaction taking place in the process are double-replacement reaction and decomposition reaction. The double-replacement reaction is the reaction between magnesium carbonate and nitric acid while the decomposition is the breaking down of the carbonic acid into water and CO2.
Answer:The Peruvian west coast bordering the Pacific Ocean is a long desert strip that stretches from the departments of Tumbes in the north bordering Ecuador, to Tacna in the south bordering Chile for a total length of 1,555 miles or 2,500 km. The average temperature from December to April is 25 to 28C or 53 to 59F and the average temperature from May to November is 12 to 15C or 53 to 59F.
The coast covers about 10% of the territory but is home to more than 50% of the population. Large cities such as Lima, the capital, Trujillo, Chiclayo and Tacna are located in the coast. Cities along the coast are the center of economic activity attracting people from the interior of the country looking for economic prosperity.
idk hope this helps !!!!
