Explanation:

1) When phosphoric acid reacts with calcium hydroxide neutralization reaction takes place in which calcium phosphate is formed along with formation of water.

The balanced chemical equation is give as:

$2H_3PO_4+3Ca(OH)_2\rightarrow Ca_3(PO_4)_2+6H_2O$

2) When calcium oxide acid reacts with phosphorus pentoxide addition reaction takes place in which calcium phosphate is formed.

The balanced chemical equation is give as:

$3CaO+P_2O_5\rightarrow Ca_3(PO_4)_2$

An intravenous saline drip has 9.8 g of sodium chloride per liter of water. by definition, 1 ml = 1 cm3.

ELEN [110]

Missing question: Express the salt concentration in kg/m³.
Answer is: the salt concentration is 9.8 kg/m³.
m(NaCl) = 9.8 g ÷ 1000 g/kg.
m(NaCl) = 0.0098 kg.
V(solution) = 1 L = 1 dm³.
V(solution) = 1 dm³ ÷ 1000 dm³/m³.
V(solution) = 0.001 m³.
d(solution) = m(NaCl) ÷ V(solution).
d(solution) = 0.0098 kg ÷ 0.001 m³.
d(solution) = 9.8 kg/m³.
