Answer #1

+4        0              -2      -4

CH4 + 2O2   2H2O + CO2

Here the oxidation state of C decreases from +4 to -4 that menas there is change of 8 units so the number of electrons transferred are 8.

We know that

Where

F = Faraday = 96500 C

n = Number of electrons transferred = 8

= -818 KJ/mol

         = - 818 x10 3 J/mol

Plug the values we get

The combustion of methane, CH4, releases 890.4 kj/mol of heat. That is, when one mole of methane is burned, 890.4 kj are give off to the surroundings. This means that the products have less energy stored in the bonds than the reactants. Thus, for the reaction: CH4(G) + 2 O (g) -> CO2 (g) + 2 H2O (I) deltaH= -890.4kj/mol. A) what is the enthalpy change when 2.00 mol of CH4 are burned? B)what is the enthalpy change when 22.4g...
