in part 2 of the lab you practice balancing chemical reactions which just means making the total number of atoms and each type on both sides of the equation equal. are you allowed to change the coefficients in a chemical reaction?

• yes
• no
• sometimes

Explanation:

Balancing chemical equations requires equalizing atom counts on both sides. Coefficients (numbers before chemical formulas) are adjusted to achieve this, as they represent the number of moles/molecules of each substance, without altering the chemical identity of reactants or products. Changing subscripts would modify the substances themselves, which is not allowed, but coefficients are intended for balancing.

Answer:

Yes
