Conservation of Matter states that the reactants have to equal the . A. products B. enablers

2. Products and reactants in a balanced chemical reaction have the same number of of each element.
A. atoms B. molecules

3. If the equation on the board had shown 3 atoms of carbon on the reactants side, how many atoms of carbon would need to be represented on the products side?
A.2 B.3

1. A. Products

2. A. Atoms

3. B. (3)

Explanation:

1. Conservation of Matter states that the reactants have to equal the products.

2. Products and reactants in a balanced chemical reaction have the same number of atoms of each element.

3. Three (3) atoms of carbon would need to be represented.

Number of atoms on the left and on the right side of the balanced chemical reaction is the same, for example: Mg + 2HCl → H₂ + MgCl₂. There are two hydrogen atoms, two chlorine atoms and one magnesium atom on both side of chemical reaction.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
