At high temperatures, calcium carbonate (CaCO3) decomposes to form calcium oxide (CaO) and carbon dioxide (CO2) gas. The average

mass of 1 calcium oxide molecule is 56.079 amu, and the average mass of 1 carbon dioxide molecule is 44.009 amu.
CaCO3 CaO + CO2
Which is the total mass of the 1 calcium carbonate molecule?
A. 12.070 amu
B. 44.009 amu
C. 56.079 amu
D. 100.088 amu

Answer:

Option D is correct

Explanation:

The individual mass of reactants in the reaction are

Calcium Oxide (CaO) =  56.079 amu

Carbon dioxide (CO2) = 44.009 amu

Since this reaction is a simple addition reaction in which no mass of the reactants is wasted. Also, no energy is released accompanied by conversion of mass into energy.

Hence, total mass of reactants would be equal to the mass of the product.

Thus, mass of calcium carbonate i.e CaCO3  is

= 56.079 + 44.009 \\

= 100.08 amu

Hence, option D is correct

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 .
