How many molecules of Carbon
Dioxide (CO2) are there in 2 CO2?

There are 2 molecules of Carbon dioxide(CO2)

Given

Molecules of CO2

Required

The number of molecules

Solution

The coefficient of a molecule shows the number of that molecule, while the subscript after the name of the atom indicates the number of that atom in the molecule

Because there is a coefficient of 2 in front of the CO2 molecule, then the number of CO2 molecules is 2

relative humidity is a measure of the amount of moisture in the air relative to the total amount of moisture the air can hold.

so d

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
