Answer:
C - LiOH
Explanation:
To balance this, first, you need to put all things in a row.
substances --> products
Li2O + H20 --> products
You know Li is an alkaline metal and with water will form a hydroxide so, LiOH will be the product.
Li2O + H20 --> LiOH
Now, you have to balance this to have the right amount in the equation:
Li2O + H20 --> 2 LiOH
And that's it.
