Answer:
At least 6. You have to look at the chemical formula for cellular respiration and make sure it is balanced!
C6H12O6+6 O2→6 CO2+6 H2O
Explanation:
Without mechanical ventilation to provide fresh air, moisture, odors, and other pollutants can build up inside a home. Mechanical ventilation systems circulate fresh air using ducts and fans, rather than relying on airflow through small holes or cracks in a home's walls, roof, or windows.

Answer:
b. The number of each type of atom is the same for both the reactants and products.
Explanation:
A balanced chemical equation is characterized by each of the atoms of the reactants and the products being equal to each other. The atoms present in the reactants are also present in the products but are just rearranged. The equal number of atoms from both sides of the equation (reactants and products) follow the Law of Conservation of Mass.
