Question

In the chemical equation wa + xb →yc + zd, if you know the number of moles of a that react, you can determine _____. the number of moles of b, c, and d the number of moles of b only the total number of moles of c and d only the total number of moles of a and b only

Answer 1

Hello!

In the chemical reaction: wA+xB → yC + zD if we know the number of moles of A that react we can determine the number of moles of B, C, and D.

If we know the limiting reactant of any given chemical reaction, we can know the moles of the other reactants and products. For this reaction the conversion factor for determining the moles of the other substance is the following:

$moles A* \frac{x moles B}{w moles A}=molesB \\ \\ moles A* \frac{y moles C}{w moles A}=molesC \\ \\ moles A* \frac{z moles D}{w moles A}=molesD$

Have a nice day!
