Answer:
1CO + 2H₂ —> 1CH3OH
Step-by-step explanation:
When balancing any chemical equation given, you identify the amount of reactants and amount of products.
From our given equation;
__CO +__ H₂ —> __CH3OH
Reactants
C = 1
O = 1
H = 2
Products
C = 1
O = 1
H = 3 + 1 = 4
This shows that Hydrogen is not balanced we require 2 to balance it. Thus giving us;
1CO + 2H₂ —> 1CH3OH,
Which is balanced.
