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

Apeak with a retention time of 407 s has a width at half-height (w1/2) of 7.6 s. a neighboring peak is eluted 17 s later with a w1/2 of 9.4 s. a compound that is known not to be retained was eluted in 2.5 s. the peaks are not baseline resolved. how many theoretical plates would be needed to achieve a resolution of 1.5?
