Question

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: A+B→AB 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.) Express your answer as an integer.

Answer 1

5000 molecules of A will needed to react with 5000 molecules of B to gives 5000 molecules of AB.

Step-by-step explanation:

A+B → AB

Given that 100 molecules of A combines with 100 molecules of B to give 100 molecules of AB.

According to reaction, 1 molecule of AB is produced by 1 molecule of A.

Then 5000 molecules of AB will be given by:

`(1)/(1)* 5000 molecules=5000`molecules of A

5000 molecules of A will needed to react with 5000 molecules of B to gives 5000 molecules of AB.
