Calcium carbonate decomposes on heating to form calcium oxide and carbon dioxide. If 0.5g of calcium carbonate is heated in this way.
a)What mass of calcium oxide is formed
b)The mass and volume of carbon dioxide formed at RTP

(a) calcium forms the Molar mass of CaO is 40+16 g=56g.

Mass of CaO obtained 56x3 g= 168 g CaO

(b)

2b2t

explanation:

2b2t

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
