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

 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 : 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,

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

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.

the answers would be

the first one and the second one
