Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the law of conservation of matter?
A
The Law of Conservation of Matter states that during a reaction matter can be created and destroyed
B
The Law of Conservation of Matter states that during a reaction no matter is created nor destroyed.
C
The Law of Conservation of Matter states that matter goes through changes called a phase change
D
None of the above
Explanation: 

Detailed explanation-1: -Matter can change form through physical and chemical changes, but through any of these changes matter is conserved. The same amount of matter exists before and after the change-none is created or destroyed. This concept is called the Law of Conservation of Mass.

Detailed explanation-2: -The Law of Conservation of Mass dates from Antoine Lavoisier’s 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.

Detailed explanation-3: -The Law of Conservation of Matter says that the amount of matter stays the same, even when matter changes form. Sometimes it may seem that matter disappears during a science experiment, but this law tells us that matter cannot magically appear or disappear, it simply changes from one form to another.

Detailed explanation-4: -Because the law of conservation of matter states that matter cannot be created or destroyed, in a chemical equation– Group of answer choices. the number of atoms of each element in the reactants must be the same in the products.
