1. What mass of natural gas (CH4) must you burn to emit 260 kJ of heat? CH4(g)+2O2(g)→CO2(g)+2H2O(g) ΔH∘rxn=−802.3kJ 2.Consider the following thermochemical equation for the combustion of acetone, C3H6OC3H6O, the main ingredient in nail polish remover: C3H6O(l)+4O2(g)→3CO2(g)+3H2O(g)ΔH∘rxn=−1790kJ If a bottle of nail polish remover contains 173 mL of acetone, how much heat would be released by its complete combustion? The density of acetone is 0.788 g/mL 3.Zinc metal reacts with hydrochloric acid according to the following balanced equation: Zn(s)+2HCl(aq)→ZnCl2(aq)+H2(g) When...
What element is undergoing oxidation (if any) in the following reaction? CH4(g) + 2O2 (g) -> CO2(g) + 2H2O (g) 1. H 2. O 3. C
Exactly 17.550 g of O2 is required to completely burn a 5.000 g mixture of CH4 and C2H2 yielding only CO2 and H2O. How many grams of C2H2 were in the original mixture? The combustion equations are: CH4(g) + 2 O2(g) ----> CO2(g) + 2 H2O(g) C2H2(g) + 5/2 O2(g) ----> 2 CO2(g) + H20(g)
In the presence of excess oxygen, methane gas burns in a constant-pressure system to yield carbon dioxide and water: CH4(g) + 2O2(g) → CO2(g) + 2H2O(l) ΔH = -890.0 kJ Calculate the value of q (kJ) in this exothermic reaction when 1.10 g of methane is combusted at constant pressure.
Balanced equation: CH4(g)+2O2(g)→CO2(g)+2H2O(g) Part B: What mass of carbon dioxide is produced from the complete combustion of 2.70×10−3 g of methane? Part C: What mass of water is produced from the complete combustion of 2.70×10−3 g of methane? PartD: What mass of oxygen is needed for the complete combustion of 2.70×10−3 g of methane?
