Question

Lithium and bromine react to form lithium bromide. How many moles of bromine must be used to produce 5.5 moles of lithium bromide?

Answer 1

Step-by-step explanation

Given that

The number of moles lithium bromide is 5.5 moles

Firstly, write a balanced equation for the reaction

`\text{ 2Li + Br}_2\rightarrow\text{ 2LiBr}`

Find the number of moles of bromine using stoichiometry ratio

Let x represents the number of bromine
