Shown below is a chemical reaction. fe + cucl2 mc009-1.jpg fecl2 + cu which pair of substances are the products?

The products are and

Explanation: The chemical reaction is written in terms of chemical formulas by writing the reactants on the left hand side and the products on the right hand side separated by an arrow.

This is an example of single displacement reaction where a more reactive element displaces a lesser reactive element from its salt solution.

Thus the reactants are iron and Copper chloride and the products are iron chloride and copper .

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
