How many moles of calcium chloride would react with 5. 99 moles of aluminum oxide?

slega [8]

There are 17.97 moles of calcium chloride would react with 5. 99 moles of aluminum oxide .

The balanced chemical equation between reaction between calcium chloride and aluminum oxide is given as,

$3CaCl_{2} (aq)+Al_{2} O_{3} (s)$ → $3CaO_{2} (s)+2Al Cl_{3} (aq)$

The molar ratio of above reaction is 3:1

It means 3 moles of calcium chloride is require to react one mole of aluminum oxide.

The number of moles of calcium chloride requires to react with 5. 99 moles of aluminum oxide = 3 × 5. 99 = 17.97 moles

The equation in which number of atoms of elements in reactant side is equal to the number of atoms of elements in product side is called balanced chemical equation .
