How does the law of conservation of matter apply to chemical equations?
A. The sum of the coefficients on each side of the equation must be the same.
B. The sum of the atomic masses on both sides of the equation must be the same.**
C. The sum of the atomic numbers on both sides of the equation must be the same.
D. The total number of atoms of each element on both sides of the equation must be the same.
B is correct!
Thank you ^-^
do you balance chemical equations by atoms or mass?
D may be more appropriate
R_Scott is right on. Sophia missed the boat.
Whew, Someone (R Scott and Dr Bob) caught it before I saw it.
The correct answer is D. The total number of atoms of each element on both sides of the equation must be the same.
The law of conservation of matter states that matter cannot be created or destroyed in a chemical reaction. This means that the total mass and number of atoms must remain constant before and after a reaction.
In a chemical equation, you have reactants on the left side and products on the right side, separated by an arrow. Each element is represented by its chemical symbol, and the number of atoms of each element is indicated by a coefficient placed in front of the symbol or formula.
To determine if the law of conservation of matter is satisfied in a chemical equation, you need to balance it. Balancing involves adjusting the coefficients in front of the reactants and products to ensure that the total number of atoms of each element is the same on both sides of the equation.
So, in this case, the correct answer is D because the law of conservation of matter is applied by making sure that the total number of atoms of each element is the same on both sides of a chemical equation.
