One molecule of calcium oxide, CaO, and one molecule of carbon dioxide, CO2, combine in a chemical reaction to form one substance. Given that matter is neither created nor destroyed, which chemical formula is the product of this reaction?(1 point)
Answers
Answer:
CaCO3 is the product of the of this reaction
Given info : one mole of calcium oxide , CaO and one molecule of carbon dioxide CO₂ combine in a chemical reaction to form one substance.
To find : the chemical formula is the produced of this reaction..
solution : According to Antoine Lavoisier's law of conservation of mass. the mass is neither created nor destroyed. which means, mass of of an element at the beginning of the reaction will equal the mass of the element at the end of the reaction.
here, one molecule of calcium oxide and one molecule of carbon dioxide combine in a chemical reaction to form one substance and that substance is calcium carbonate.
in chemical reaction,
CaO + CO₂ ⇒ CaCO₃
here, you see, one of Ca element in reactants = no of Ca in product
no of O element in reactants = no of O in product.
no of C in reactants = no of O in product.
hence, it follows the law of conservation of mass. so the chemical formula of product is CaCO₃
