A synthesis reaction takes place when carbon monoxide (CO) and hydrogen gas (H2) react to form methanol (CH3OH). How many grams of
methanol are produced when 7.0 grams of carbon monoxide reacts with excess hydrogen gas? (5 points)

20 grams
7.0 grams
8.0 grams
6.1 grams

Explanation:

Write the balance equation for the reaction taking place:

CO(g) + 2H2(g) ==> CH3OH ... balanced equation

Find the limiting reactant:

Because according to the balanced equation it takes 2 moles H2 for every 1 mole CO, there isn't enough H2, so it is limiting and will dictate how much CH3OH can be made.

Mass of CH3OH produced = 0.75 moles H2 x 1 mol CH3OH / 2 mol H2 x 32 g CH3OH / mol = 12 g CH3OH

its first and third is your answer i did the qustion the fourth isnt right
