Answer:
in a chemical reaction, the mass of the products will always be equal to the mass of the reactants.
Explanation:
The choices can be found elsewhere and as follows:
a. mass-mass problems
<span>b. mass-volume problems </span>
<span>c. mass-particle problems </span>
<span>d. volume-volume problems
</span>
I believe the correct answer is option D. It is volume-volume problems that does not require the use of molar mass. <span> Here you are dealing with molarities and volumes to determine concentrations. Molar mass is not part of any calculations.</span>
D) warm and wet.
Water can be a catalyst, and heat speeds up reactions.
