Answer: The Diver's air tank is filled with oxygen gas.
The filling of air tank while keeping in water can be explained in reference to the Charles' Law.
Charles' Law: It states that the volume of the ideal gas is directly proportional to the absolute temperature at constant pressure.
(at constant Pressure)
The Scuba tank contains cold water and is present at high pressure. The gas which is put in the tank will be compact and would not expand. As the temperature is low inside the tank, hence by using Charles' Law, the volume will also decrease inside the tank.
When the air tank is filled, it is always kept in a tub of water because the pressure is high and hence, more oxygen gas can be filled inside the air tank.
Answer:
Theoretical yield = 3.51 g
Explanation:
The formula for the calculation of moles is shown below:
For :-
Mass of = 1.28 g
Molar mass of = 16.04 g/mol
The formula for the calculation of moles is shown below:
Thus,
For :-
Mass of = 10.1 g
Molar mass of = 31.998 g/mol
The formula for the calculation of moles is shown below:
Thus,
According to the given reaction:
1 mole of methane gas reacts with 2 moles of oxygen gas
0.0798 mole of methane gas reacts with 2*0.0798 moles of oxygen gas
Moles of oxygen gas = 0.1596 moles
Available moles of oxygen gas = 0.3156 moles
<u>Limiting reagent is the one which is present in small amount. Thus, is limiting reagent.
</u>
The formation of the product is governed by the limiting reagent. So,
1 mole of methane gas on reaction produces 1 mole of carbon dioxide.
0.0798 mole of methane gas on reaction produces 0.0798 mole of carbon dioxide.
Mole of carbon dioxide = 0.0798 mole
Molar mass of carbon dioxide = 44.01 g/mol
The formula for the calculation of moles is shown below:
Thus,
Mass of = 3.51 g
<u> Theoretical yield = 3.51 g</u>
