A student needs to conduct a reaction that combines chemicals A and B to synthesize product AB. If we write this as a chemical equation it looks like:
[tex]A+B \rightarrow AB[/tex]
If this student combines 100 molecules of A and 100 molecules of B, the student obtains 100 molecules of AB.
How many molecules of A would this student need to make 5000 molecules of AB? (Assume the student had enough of molecule B to make 5000 molecules of AB.)

Respuesta :

Answer:

5000 molecules of A

Explanation:

This is the reaction

A + B → AB

If

100A + 100B → 100AB

then

5000A + 5000B → 5000AB

because both reactants are required in equal amounts to give the same amount of product.
