Deadline: June 15th. ( School closes on that day, and I can't submit my Chemistry Study Journals for Extra Credit, afterward. ) Hi, I'm studying in a Chemistry journal, and got stuck on a practice question:
If 5 moles of carbon monoxide react with 2.3 moles of hydrogen gas, how many moles of methanol can be produced?
CO + 2H2 → CH3OH

So I was wondering if I would use a balanced equation, or like, solve it like one, or something like that. I dunno, I'm kinda lost, stuck I guess...

Read it CAREFULLY: It's a balanced equation, so your gonna have to solve it like one.

We have 5 moles of carbon monoxide, reacting to 2.3 moles of hydrogen gas.

So the answer would be from a balanced equation.

Use a periodic element table to figure out the rest.

It should be easy from here.

I hope this helps. :D

Explanation:

From the equation:

CO + 2H2 → CH3OH

Adding 1 to CO and CH3OH

1 CO + 2 H2 → 1 CH3OH

So the ratio of CO, H2 and CH3OH is 1:2:1

That means: 1 mole of CO will react with 2 moles of H2 to form 1 moles of CH3OH

With 5 moles of CO and 2.3 moles of H2, there are more CO than H2. So H2 is the limiting factor.

Going with the 2:1 ration, there will be 2.3/2 = 1.15 moles of CH3OH produced.

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
