According to the kinetic molecular theory, as the volume of a gas increases: the number of particle impacts per unit area increases the temperature must change the total number of particle impacts increases the number of particle impacts per unit area decreases

As the volume of a gas increases at constant temperature, the number of particle impacts per unit area decreases.

There is the same number of impacts, but they are spread over a larger surface area.

Thus, the number of impacts per unit area decreases.

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.

hope this : -)

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.
