what is the enthalpy of complete combustion of methane to give gaseous products?
Homework Answers
CH4(g) + 2O2(g) ---------> CO2(g) + 2H2O(g) combustion reaction.
Hrxn
= [H0f(CO2)
+ 2H0f(H2O)]
- [H0f(CH4)
+ 2H0f(O2)]
Hrxn
= [-393.509 + 2(-241.818)] - [- 74.81 + 2 (0) ]
Hrxn
= - 802 KJ/mol

please answer part 2
Solving Tora gaseous Combustion of hydrocarbons such as methane (CH) produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earth's atmosphere can trap the Sun's heat, raising the average temperature of the Earth. For this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide. 1. Write a balanced chemical equation, including physical state symbols, for the combustion of gaseous methane into gaseous carbon dioxide and...
What mass of water is produced from the complete combustion of 8.90x10-3 g of methane?
Complete combustion of methane When methane (CH4) burns, it reacts with oxygen gas to produce carbon dioxide and water. The unbalanced equation for this reaction is CH4(g) + O2(g) → CO2 (g) + H2O(g) This type of reaction is referred to as a complete combustion reaction.Part C What mass of water is produced from the complete combustion of 8.90x10-3 g of methane? Express your answer with the appropriate units.

A gaseous fuel mixture contains 25.3% methane (CH4), 38.2% ethane (C2H6), and the rest propane (C3H8) by volume. When the fuel mixture contained in a 1.76 L tank, stored at 756 mmHg and 298 K, undergoes complete combustion, how much heat is emitted? (Assume that the water produced by the combustion is in the gaseous state.) Express your answer with the appropriate units.
