Question

Which word equation shows lithium oxide being formed from the reaction between oxygen and lithium?

1.)oxygen + lithium oxide to lithium

2.)lithium + oxygen to lithium oxide

3.)oxygen + lithium to lithium + oxide

4.)lithium oxide to lithium + oxygen

Answer 1

 The correct answer is the second option. The word equation that would represent the formation of lithium oxide from lithium metal and oxygen is:

lithium + oxygen to lithium oxide

In chemical symbols, the balanced chemical equation is expressed as:

Li + O2 = Li2O

Answer 2

Answer : The correct option is, (2) lithium + oxygen to lithium oxide

Explanation :

When the lithium react with the oxygen to give lithium oxide as a product.

The balanced chemical reaction will be,

$2Li+O_2\rightarrow Li_2O$

This reaction can be represented in words as,

Lithium react with oxygen to give lithium oxide.

or,

lithium + oxygen to lithium oxide

Hence, the correct option is, (2) lithium + oxygen to lithium oxide
