Ch4 + 2o2 → co2 + 2h2o, δh = -890 kj/mol how much energy is released when 59.7 grams of methane (ch4) reacts with oxygen?

- 3321 kJ of heat is released.

Solution:- The given balanced equation is:

From this balanced combustion equation, 890 kJ of heat is released by the combustion of 1 mol of methane.

We could convert given grams of methane to moles and multiply by the delta H value of the reaction to get the total heat released by the combustion of 59.7 grams of methane as:

= -3321 kJ

The negative sign indicates the heat is released. So, 3321 kJ of heat is released by the combustion of 59.7 grams of methane.

bcde is the incorrect answer it is a

i think its 100

i hope this !
