Question

lisa is investigating a chemical reaction involving carbon compounds. which of these results could not occur, according to scientific laws about chemical reactions, matter, and energy? (c) the mass of carbon in the products is greater than the mass of carbon in the reactants. (d) the mass of carbon in the products is equal to the mass of carbon in the reactants. (e) the reaction occurs faster in the presence of a certain protein. (b) the reaction absorbs energy from the environment. (a) the reaction releases energy to the environment. which of the following are true about cellulose? (2) it is a major component of plant cell walls it is soluble

Explanation:

According to the law of conservation of mass, in a chemical reaction, the mass of each element in the products must equal the mass of that element in the reactants. So, the mass of carbon in the products cannot be greater than the mass of carbon in the reactants. Proteins can act as enzymes (biological catalysts) to speed up reactions. Reactions can be endothermic (absorb energy) or exothermic (release energy). Cellulose is a major component of plant cell walls and is insoluble.

Answer:

C. The mass of carbon in the products is greater than the mass of carbon in the reactants.
