Answer:
11.66 L.
Explanation:
- We can use the general law of ideal gas: <em>PV = nRT.</em>
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
- If P and T are constant, and have different values of n and V:
<em>(V₁n₂) = (V₂n₁).</em>
V₁ = 25.5 L, n₁ = 3.5 mol.
V₂ = ??? L, n₂ = 3.5 mol - 1.9 mol = 1.6 mol.
<em>∴ V₂ = (V₁n₂)/(n₁)</em> = (25.5 L)(1.6 mol)/(3.5 mol) =<em> 11.66 L.</em>
Answer:
It is observed that H2 gas gives out 286kJ/m, Methane gives out 802.3kJ/m and hexane gives out 4163kJ/m of heat. They are all exergonic or exothermic reaction but have different values of heat given out. The amount of carbon atom present, is what determines the heat given out, as higher carbon compound like Hexane gave out more heat than Methane and Hydrogen gas have out the least.
