Quicklime (CaO) is produced by the thermal decomposition of calcium carbonate (CaCO3). Calculate the volume of CO2 at STP produced from the decomposition of 152 g CaCO3 by the reaction.

CaCO3 —> CaO + CO2

V = 34.1 L

Explanation:

Given data:

Mass of CaCO₃ = 152 g

Volume of CO₂ produced = ?

Solution:

Chemical equation:

CaCO₃   →   CaO  + CO₂

Number of moles of CaCO₃ :

Number of moles = mass/ molar mass

Number of moles = 152 g / 100 g/mol

Number of moles = 1.52 mol

Now we will compare the moles of CaCO₃ with  CO₂

                            CaCO₃             :            CO₂

                                  1                 :              1

                               1.52              :            1.52

Volume of CO₂:

PV = nRT

Standard temperature = 273 K

Standard pressure = 1 atm

R = 0.0821 atm.L/mol.K

Now we will put the value sin formula:

V = nRT/P

V = 1.52 mol × 0.0821 atm.L/mol.K × 273 K /  1 atm

V = 34.1 L

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
