When calcium carbonate is heated, it breaks down into calcium oxide and carbon dioxide. CaCO3(s) →CaO(s) + CO2(g)

You heat 2.0 moles CaCO3.

How many moles of carbon dioxide(CO2) will you make?

Question options:

a.) 2 moles CO2

b.) 0.50 moles CO2

c.) 1 mole CO2

d.) 4 moles CO2

What is the typical rotational frequency frot for a molecule like n2 at room temperature (25∘c)? assume that d for this molecule is 1å=10−10m. take the total mass of an n2 molecule to be mn2=4.65×10−26kg. you will need to account for rotations around two axes (not just one) to find the correct frequency. express frot numerically in hertz, to three significant figures.
