: Modeling Chemical Reactions

Due 02/01/21 11:59
Keesha performed a chemical reaction, and the products looked quite different from the reactants She knew the amount of matter had not changed due
to the law of conservation of mass According to the law or conspivation of mass, what happens in a chemical reaction?
A Matter is not created or destroyed and the same amount of mass remains
B A new kind of matter is created and the amount of mass either increases or decreases
C Matter is not created or destroyed and the amount of mass may change after the reaction
D. New matter is created and changes form so that the mass of the reactants and the products will almost be equal
no

Answer 1

A Matter is not created or destroyed and the same amount of mass remains

Step-by-step explanation:

In a chemical reaction, according to the law of conservation of matter, "matter is neither created nor destroyed and the same amount of mass remains in such a process".

• New kinds of products are formed in a chemical reaction because they undergo chemical changes.
• The chemical changes results in energy changes and formation of new kinds of substances.
• Based on the law of conservation of matter, mass is constant.
• Mass is not lost or gained.
