3. Chemical Reactions

The following reaction shows the mineral ilmenite, FeTiO₃, being reacted with chlorine gas and sand in order to extract titanium (IV) chloride. 

FeTiO₃ (s)  +  3 Cl₂ (g)  +  3 C (s) → 3 CO (g)  +  FeCl₂ (s)  +  TiCl₄ (g) 

Assuming a 100% yield, how many grams of titanium (IV) chloride can be extracted when reacting 18.0 g ilmenite, 30.0 g Cl₂ and 40.0 g C?

Lithium solid reacts with oxygen gas to create lithium oxide solid.

4 Li (s)  +  O₂ (g)  →  2 Li₂O (s)

If 131 g of Li are allowed to react with 215 g O₂, how many kilograms of the excess reactant would remain?

Nitrogen and hydrogen combine at a high temperature, in the presence of a catalyst, to produce ammonia. N₂(g) + 3H₂(g) ⟶ 2NH₃(g) there are four molecules of nitrogen and nine molecules of hydrogen present in the diagram. When the reaction is complete, how many molecules of NH₃ are produced?

1 moles of mn reacts with 1 moles of O₂. What is the theoretical yield of the product? 𝗠𝗻(𝘀) + 𝗢₂(𝗴) → 𝗠𝗻𝗢₂(𝘀)
