balance the following chemical equations: li + o₂ → li₂o
balance the following chemical equations: li + o₂ → li₂o
Answer
Explanation:
Step1: Balance oxygen atoms
On the left - hand side, we have 2 oxygen atoms in $O_2$, and on the right - hand side, we have 1 oxygen atom in $Li_2O$. To balance the oxygen atoms, we put a 2 in front of $Li_2O$: $Li + O_2\rightarrow2Li_2O$.
Step2: Balance lithium atoms
Now, on the right - hand side, we have 4 lithium atoms in $2Li_2O$. So, we put a 4 in front of $Li$ on the left - hand side. The balanced equation is $4Li+O_2\rightarrow2Li_2O$.
Answer:
4, 2
