Question

Helpppppppppp!!! the law of conservation of mass states that during a chemical reaction, mass/matter is not __________________________ or ________________________. because of this law, there must be exactly the same number and kind of _____________________ on each side of a chemical equation. to check if an equation is balanced or not, simply count the number of atoms of each element on the reactant side of the equation and check to see if there are the same number of atoms of each element on the ______________________ side of the equation. if so, it is balanced.

Answer 1

Answer: created, destroyed, element, product

Explanation: The law of conservation of mass states that matter can neither be created nor destroyed but is transferred from one form to another. In other words, the mass of one element at the beginning of the reaction must be equal to the mass of the element at the end of the reaction.
So...the law of conservation of mass states that during a chemical reaction, mass/matter is not CREATED or DESTROYED and because of this law, there must be exactly the same number and kind of ELEMENTS on each side of a chemical equation.
To check if an equation is balanced or not, simply count the number of atoms of each element on the reactant side of the equation and check to see if there are the same number of atoms of each element on the PRODUCT side of the equation. If so, it is balanced.
