What is the density of carbon dioxide gas if 2g occupies a volume of 10ml?

Molar mass=2×Vapour density

Given, Vapour Density=11.2

Molar mass=11.2×2=22.4g/mol

No.of moles of gas=

22.4

10

​

≅0.45moles

At STP, 1 mole occupies 22.4L volume.

0.45 moles occupy 22.4×0.45=10 L volume.

∴ Volume occupied is 10 litres.

Explanation:

a electronegativity decreases beacuse the size of nucleus is bigger.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
