Write the reaction equations: Calcium – Calcium oxide – Calcium hydroxide –

Write the reaction equations: Calcium – Calcium oxide – Calcium hydroxide – Calcium nitrate – Calcium carbonate – Calcium oxide – Calcium silicate

2 Ca + O₂ = 2 Cao;

CaO + H₂O = Ca (OH) 2;

Ca (OH) + 2 HNO₃ = Ca (NO₃) ₂ + 2 H₂O;

Ca (NO₃) ₂ + CO₂ + H₂O = CaCO₃ + 2 HNO₃;

CaCO₃ = CaO + CO₂ (heating 900 – 1200 C);

CaO + SiO₂ = CaSiO₃ (heating 1100 – 1200 C);
