Will give brainliest + 60 points ! professor bothwell determined from the wrapper the number of calories in a candy bar. he then burned the entire candy bar and measured the amount of heat released. his experiment was most likely designed to demonstrate a the law of conservation of matter b the law of disorder c the law of conservation of energy d the law of constant composition

His experiment was most likely designed to demonstrate the law of conservation of energy, which states that energy the total energy of an isolated system remains constant; it is said to be conserved over time. This law means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another. So, he was trying to demonstrate that the amount of heat energy released was equal to the number of calories (amount of energy) stated to be in the candy bar.

explanation:

dasdad

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.
