Question

How many cao will be produced by decomposition of 5gcaco3

Answer 1

Answer:

the amount of CaO produced from g grams of Calcium carbonate is 2.8 grams

Explanation:

The chemical equation of decomposition of CaCO₃ is

CaCO₃→CaO + CO₂

we know that:

The molar mass of CaCO₃ = 100$g/mol$

The molar mass of CaO = 56 $g/mol$

From the balanced chemical equation, one mole of CaCO₃ gives one mole of CaO.

That means 100 grams of calcium carbonate on decomposition gives 56 grams of calcium oxide.

So one gram of Calcium carbonate will give = $\frac{56}{100} = 0.56 gram$ of calcium oxide.

Therefore, the amount of CaO produced from g grams of Calcium carbonate = 0.56×5 = 2.8 grams
