Question

The circle below represents a mixture of A2 and B2 before they react to form AB3.

How many molecules of product can form?

Step-by-Step Solution

Answer

The circle containing a mixture of A₂ and B₂ before reacting to form AB₃.

In this case we know that A₂ is the limiting raegent.

Therefore 2 moles of products has formed from 1 moles of A₂ and 3 moles of  B₂  

Step 1. Finding the limiting reactant.

In this case, we know that A₂ is the limiting reactant.

${\mathrm{A}}_2+3{\mathrm{B}}_2\to 2{\mathrm{AB}}_3$

The circle containing a mixture of A₂ and B₂ before reacting to form AB₃.

Step 2. Final result

${\mathrm{A}}_2+3{\mathrm{B}}_2\to 2{\mathrm{AB}}_3$

Here we have to write how many molecules of product can form

The amount of product formed from the raection between A₂ and B₂ can be known from balanced equation:

${\mathrm{A}}_2+3{\mathrm{B}}_2\to 2{\mathrm{AB}}_3$

Therefore, 2 moles of products has formed from 1 moles of A₂ and 3 moles of  B₂.
