3 Quantitative chemistry

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

The word equation for the reaction is:

\text{titanium} + \text{chlorine} \rightarrow \text{titanium chloride}

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

	Mass in $g\text{g}$
Crucible and lid	$18.40$
Crucible, lid and titanium	$19.60$
Crucible, lid and titanium chloride	$23.15$

Calculate the simplest whole number ratio of:

\text{moles of titanium atoms} : \text{moles of chlorine atoms}

[4]

Determine the balanced chemical equation for the reaction.

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