Which statement best represents the law of conservation of matter with regard to chemical reactions
1. The reactants and products have the same number and type of atoms, but the atoms may be recombined.
2.It shows how many molecules there are of a particular substance.
3. NaOH + HCl → NaCl + H2O
4.Atoms always remain intact during chemical reactions.
5. Ans: (4, 4) for q's Which numbers balance this equation?
gabs is right 5/5
The law of conservation of matter states that in any chemical reaction, mass is neither created nor destroyed. This means that the total mass of the reactants must be equal to the total mass of the products. Therefore, the statement that best represents the law of conservation of matter with regard to chemical reactions is:
"The total mass of the reactants is always equal to the total mass of the products in a chemical reaction."
To determine if this statement is correct, one can balance the chemical equation by adjusting the coefficients of the reactants and products. The coefficients represent the number of molecules or moles involved in the reaction. By ensuring that the same number of atoms of each element is present on both sides of the equation, the law of conservation of matter is upheld.
