What is the ratio between coefficients of Fe to Cu in Hypothesis I? Hypothesis I: Fe + CuCl2 --> Cu + FeCl2

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.

the answer is 75.0%.

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

answer; 4 electrons;
