An engineer investigated the synthesis of titanium chloride by reacting pure titanium metal with chlorine gas.

The word equation for the reaction is: titanium+chlorine→titanium chloride\text{titanium} + \text{chlorine} \rightarrow \text{titanium chloride}titanium+chlorine→titanium chloride

The results of the masses recorded during the reaction are shown in the table below:

a.

Calculate the simplest whole number ratio of: moles of titanium atoms:moles of chlorine atoms\text{moles of titanium atoms} : \text{moles of chlorine atoms}moles of titanium atoms:moles of chlorine atoms

b.

Determine the balanced chemical equation for the reaction.

Relative atomic masses (ArA_rAr​): Cl=35.5\text{Cl} = 35.5Cl=35.5, Ti=48\text{Ti} = 48Ti=48
