Question

Using a balanced chemical reaction and a periodic table, which of the following is not possible to calculate?

a. the molar mass of the products
b. the number of atoms in the reaction
c. the number of molecules in the reaction
d. the amount heat produced in the reaction

Answer 1

d. the amount heat produced in the reaction

Another table of values for Energy Content is required. So option D is not possible to calculate.

Answer 2

Answer: d. the amount heat produced in the reaction

Explanation: We can calculate the molar mass of the products, the number of atoms in the reaction, the number of molecules in the reaction but we cannot determine the amount of heat produced in the reaction .

To calculate the amount of heat produced, we need enthlapy and energy content which can only be provided by the energy data tables already established.

Amount of heat produced wil be the difference between the heat produced by the products and reactants.
