Answer 6

Is the link working for you

Answer 7

The question that says: 2A + B --> C right? If so.. what is your interpretation of this equation?

Answer 8

and secondly, do you know what the limiting reagent is?

Answer 9

I thought it would be D because I think you have 8 of A and 5 of B. So B is your limiting.

Answer 10

So the most you could make is 5

Answer 11

And you would have 3 red/A left over?

Answer 12

Think about this again: in this chemical reaction you need 2 molecules of A for every molecule of B. can you see why?

Answer 13

Let's count them up

We have 8 atoms A Red
and 5 atoms of B blue right?3

Answer 14

Right

Answer 15

the chemical reaction says that 2 molecules of A react for every molecule of B

Answer 16

You wouldn't multiply the 8 by 2 right and get 16?

Answer 17

let's go back first, we know that one of the reactants is going to run out first.


8 atoms of A
and 5 atoms of B.

2A + B --> C

i'm pretty sure that we need

10 atoms of A to react with 5 atoms of B.

but we only have

8 atoms of A reacting with 5 atoms of B.

so A will be the limiting reactant and we will be left with 1 atom of B left over BLUE.

Answer 18

How exactly did you figure that out?
