An inhibitor, which slows down the reaction enough to measure the release of gas.
Explanation: Number of moles of water = mass of water/ molar mass.
Molar mass of H2O = (1*2) + 16 = 18.0
Now we only need to calculate the number of moles of water.
The chemical reaction is as follows
CH4 + 2O2 ---> CO2 + 2H2O
From the eqn, the moles of H2O = 2*moles of CH4
Molar mass of CH4 = 12 + 4 = 16. Number of moles of methane = mass/
molar mass. No of moles = 6.4/16 = 0.4. So the number of mole of water = 2* 0.4 = 0.8. We already calculate its molar mass earlier. So mass of water = molar mass * number of moles = 18 * 0.8 = 14.4

Answer:
401135 kJ
Explanation:
From the balanced quation,
(q/n) = CΔE
Molar heat of combustion = 7.85kJk × (303.81-298.70)k
= 7.85kj × 5.11
= 40.1135kj
