sulphur is accompanied by
O evolution of light
O absorption of heat
O release of heat
O Both (a) and (c)​

Answer 1

Answer:

c

Explanation:

The equation for the reaction that produces the iron sulfide is: Fe + S → FeS (heat) Page 2 Maine Geological Survey | 2 One atom of iron (or a million atoms of iron) and one atom of sulfur (or one million atoms of sulfur) react with heat to make one molecule of iron sulfide (or a million molecules of iron sulfide).

Answer 2

A reaction in which heat is absorbed is called an endothermic reaction.N
