The balanced reaction is
2CH3OH (g) + 3O2 (g) ⟶ 2CO2 (g) + 4H2O (g)
as per equation two moles of methanol gas will react with 3 moles of oxygen
one mole of gas occupies 22.4 L of volume
so the moles and volume goes in same ratio
it means two unit volume of methanol will react with three unit volume of oxygen
therefore 1L of methanol gas will react with 3 /2 L of oxygen
Or 18 L of methanol gas will react with 3 x 18 /2 = 27 L of oxygen
So here oxygen is limiting reagent
As per balanced equation
10L of oxygen will react with = 2 X 10 /3 L of methanol = 6.67 L of methanol gas to give 6.67 L of CO2 gas and 13.33 L of water gas
So overall there will be = 18 - 6.67 L of left out methanol = 11.33 L
And 6.67 L of CO2 + 13.33 L of water = 20 L
Total volume of gas = 11.33+ 20 = 31.33 L
Answer: i might be wrong but i feel like it’s A. wind blowing at 3km/h just because “ energy of an object is the energy that it possesses due to its motion.”
Explanation:
The answer to the question is the first opti.on.A
<span>Petroleum and biomass are burned in combustion reactions, which liberate energy stored in chemical bonds. This is chemical energy. In contrast, nuclear energy comes from the conversion of mass into energy when an nuclear reaction occurs. Geothermal energy comes directly from heat sources underground, with no chemical or nuclear reactions.</span>
