<span>(15.0 g) / (150.0 g) x (100 g) = 10.0 g/100 g H2O </span>
<span>The answer is "D" where the number of collisions per unit area is reduced by one-half. Drawing back on the piston means the volume is increased. The pressure is reduced. There are fewer collisions when the pressure is reduced.</span>
Answer:
C) the relative number of moles taking part in the reaction
Explanation:
From a balanced chemical equation, it is always possible to determine the relative number of moles taking part in a chemical reaction.
The number of moles is the amount of the reacting specie that makes up a chemical reaction.
- In balanced chemical equation, the number of moles of reactants and products must be the same.
- From this understanding, we can determine the amount of reactants and products needed for a chemical reaction to take place.
