Question

1.Carbonate of metal x is abundant in earth crust and its hydroxide is usen in white washing .identify metal x
2.how will u convert this carbonate into its oxide . name the process and write its equation.

ANY SMART guys.. can answer....
plz help me

Answer 1

Answer:

• The metal X is Calcium.
• Its chemical formula is $CaCO_{3}$.
• It is taken as a supplement in cases of calcium deficiency.
• It is also known as limestone.
• When calcium carbonate is heated strongly, it decomposes to give out calcium oxide. This reaction is endothermic because bonds are broken.
• $CaCO_{3}$ $+$Δ → $CaO + CO_{2}$
• The process of burning the limestone is called calcination.
• Calcium oxide formed is called quick lime.
• Calcium hydroxide is called slaked lime and it is used for whitewashing.
