Which of the following is a product when Li2O and H2O react together?

A - Li2O

B - O2

C - LiOH

D - H2

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.

Just LiOH, i also think Li2O + H2O = LiOH
