Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Achemical equation shows how the combination of elementsand compounds can create different products. According to the law of conservation of matter, which of the followingis true?
A
Thereare no more atoms remaining at the end of the chemical reaction
B
Thechemical reaction can only produce compounds, not individual elements
C
Thenumber of atoms for each element remains the same throughout the chemicalreaction.
D
Thenumber of atoms for each element must increase in order for a chemical reactionto take place.
Explanation: 

Detailed explanation-1: -Matter cannot be created or destroyed in chemical reactions. This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that mass is conserved in chemical reactions.

Detailed explanation-2: -Answer: The principles of stoichiometry are based upon the law of conservation of mass. Matter can neither be created nor destroyed, so the mass of every element present in the product(s) of a chemical reaction must be equal to the mass of each and every element present in the reactant(s) in a balanced equation.

Detailed explanation-3: -The balancing of chemical equations is based on the law of conservation of mass.

Detailed explanation-4: -Answer b: The law of conservation of matter says that in chemical reactions, the total mass of the products must equal the total mass of the reactants.
