23 which term is defined as the difference between the potential energy of the products and the potential energy of the reactants in a chemical reaction? (1) activation energy (3) heat of fusion
(2) thermal energy (4) heat of reaction

(4) heat of reaction

Explanation:

1) Activation energy is defined as the extra energy required by the reactants to cross the energy barrier in order to get converted to products.

2) Heat of fusion is the the heat required to convert 1 mole of the solid into liquid state at constant pressure.

3) Thermal energy is the energy possessed by an object by virtue of its temperature.

4) Heat of reaction is defined as the difference between the potential energy of the products and the potential energy of the reactants in a chemical reaction.

calculate how many grams of ammonia can be produced from 4.21 grams of

n2 + 3h2 = 2nh3

my answer:

25.0g n2 x (1 mol/ 28.0gn2) x (2 mol nh3/ 1 mol n2) x (17.0g nh3/ 1 molnh3) = 30.36g n2

25.0g h2 x (1 mol h2/ 2.00g h2) x (2 mol nh3/ 3 mol h2) x (17.0g nh3/ 1 mol nh3) = 141.67g h2
