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.

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
