HAVE FUN LEARNING!!!( sorry im just to lazy to get the number so...)
Answer:
hey how are you
are these points for free or something
Answer:
It shows the same number of atoms of each element on both sides of the equation
A balanced equation demonstrates the conservation of mass by having the same number of each type of atom on both sides of the arrow.
Explanation:
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.
Answer:
passes
