Consider the following generic chemical equation. 2a+4b→3c what is the limiting reactant when each of the following amounts of a and b are allowed to react? part a 2 mola; 5 molb 2 ; 5 b a submitrequest answer part b 1.8 mola; 4 molb 1.8 ; 4 b a submitrequest answer part c 3 mola; 4 molb 3 ; 4 b a submitrequest answer part d 22 mola; 40 molb 22 ; 40 b a

A. Limiting reactant is A.

B. Limiting reactant is A.

C. Limiting reactant is B.

D. Limiting reactant is B.

Explanation:

It is possible to find the limiting reactant for a reaction taking the moles of a reactant that will react and using the chemical equation find the moles of the other reactant you will need.

For the reaction:

2A + 4B → 3C

A. 2 moles A requires:

2molA×= 4moles of B

As you have 5 moles of B, limiting reactant is A.

B. 1,8 moles A requires:

1,8 molA×= 3,6 moles of B

As you have 4 moles of B, limiting reactant is A.

C. 3 moles A requires:

3 molA×= 6 moles of B

As you have just 4 moles of B, limiting reactant is B.

D. 22 moles A requires:

22 molA×= 44moles of B

As you have just 40 moles of B, limiting reactant is B.

I hope it helps!
