Look at the following chemical equation 4FeS + 702 - 2Fe2O3 + 4502

What is true about this chemical equation?

A. It is unbalanced because the sum of the coefficients of the reactants is greater than the sum of the coefficients of the products.

B. It is balanced because the mass of the reactants is equal to the
mass of the products.
C. It is balanced because the sum of the coefficients of the reactants is greater than the sum of the coefficients of the products.
D. It is unbalanced because the mass of the reactants is greater than
the mass of the products.

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 yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.
