<u><em>Displacement reactions:
</em></u><em>it is the type of reaction in which reaction starts with the help of two compounds,,, but in the product the reactant that was initially with 1st compound joins with the 2nd compound..
</em><em>                     A+BC</em>⇒<em>AC+B
<u>example:
</u>Fe+CuSO4
</em>⇒<em>Cu+FeSO4</em><em>
</em><u><em>Double displacement reactions:
</em></u><em>while it is the type of reaction in which one product is obtained parts of both reacting compounds interchange with each other..
</em><u><em></em></u><em>             AB+CD</em>⇒<em>AD+BC</em><em>
<u>example:
</u>AgNO3+NaCl
</em>⇒<em>AgCl+NaNO3.....:)</em><em><u>

<u>Given:</u>

Mass of calcium nitrate (Ca(NO3)2) = 96.1 g

<u>To determine:</u>

Theoretical yield of calcium phosphate, Ca3(PO4)2

<u>Explanation:</u>

Balanced Chemical reaction-

3Ca(NO3)2 + 2Na3PO4 → 6NaNO3 + Ca3(PO4)2

Based on the reaction stoichiometry:

3 moles of Ca(NO3)2 produces 1 mole of Ca3(PO4)2

Now,

Given mass of Ca(NO3)2 =  96.1 g

Molar mass of Ca(NO3)2 =  164 g/mol

# moles of ca(NO3)2 = 96.1/164 = 0.5859 moles

Therefore, # moles of Ca3(PO4)2 produced = 0.0589 * 1/3 = 0.0196 moles

Molar mass of Ca3(PO4)2 = 310 g/mol

Mass of Ca3(PO4)2 produced = 0.0196 * 310 = 6.076 g

Ans: Theoretical yield of Ca3(PO4)2 = 6.08 g
