Question

When calcium carbonate is heated strongly, it decomposes to give calcium oxide ans
carbon dioxide.
a Write a balanced symbol equation for this reaction.
b Write a mass equation (in grams) and include the volume of carbon dioxide,
measured at r.t.p.
c What volume of carbon dioxide, measured at r.t.p., will form when each of the
following masses of calcium carbonate decomposes?
i 1.00 g
ii 25.0 g
iii 40.0 g
​

Answer 1

Answer:

I only know the first part

Caco3-->cao+co2

Answer 2

Answer:

a) Products: Materials present at the end of a reaction. Balanced chemical equation: A chemical equation in which the number of each type of atom is equal on the two sides of the equation. Subscripts: Part of the chemical formulas of the reactants and products that indicate the number of atoms of the preceding element.

b) Calculate the volume of CO2 produced in a chemical reaction by measuring the masses of the reactants (compounds caused to react, often in the presence of a catalyst, to make products) and by calculating, from the reaction equation, the moles (the standard unit to describe the amount of substance) of reactants in the equation. By calculating the moles of reactants, you can figure out the moles produced of products and, subsequently, the volume of product gas produced.

c) I don't know
