Question

Calcium carbonate decomposes on
heating to form calcium oxide and
carbon dioxide. If 100 g of
calcium carbonate decomposes
completely to form 56 g of
calcium oxide. calculate the
amount of carbon dioxide formed.
Which law of chemical
combination helped you to solve
it.

Answer 1

$\huge\mathbb{\underline{Solution:-}}$

Calcium carbonate decomposes on heating to form calcium oxide and carbon dioxide.

• If 100 grams of calcium carbonate is decomposed completely,
• it forms 56 grams of calcium oxide.

Answer 2

Explanation:

Calcium carbonate is strongly heated until it undergoes thermal decomposition to form calcium oxide and carbon dioxide. The calcium oxide (unslaked lime) is dissolved in water to form calcium hydroxide (limewater).

When Calcium Carbonate Is Heated, It Produces Calcium Oxide And Carbon Dioxide. The Equation For The Reaction Is CaCo,(s) → CaO(s) + CO. (g). How Many Grams Of Calcium Carbonate (100.09 G/mol) Must Be Decomposed To Produce 5.00 L Of Carbon Dioxide At STP?

When solid calcium carbonate is strongly heated. It undergoes thermal decomposition and forms calcium oxide and carbon dioxide.
