Answer:
B&C
Explanation:
Atoms combine in whole number ratios to form compounds.
and
Atoms cannot be created or destroyed during a chemical reaction.
Answer: False
Explanation: the masses of reactants are always the same as the products in order to conform to the law of conservation of mass.
<span>The enthalpy of an intermediate step when used to produce an overall chemical equation should be manipulated in this way:
</span><span>Multiply the enthalpy by –1 if the chemical equation is reversed.
If the forward reaction requires energy, the reverse will produce energy.</span>
