If 500,000g of limestone is heated up, what is the mass of CaO? CaCO3 = CaO + CO2

Answer 1

Well we have the stoichiometric equation........and we get over #280# #"kg"# of calcium oxide..........

#CaCO_3(s) + Delta rarr CaO(s) + CO_2(g)#

Furthermore, it is evident that the calcium oxide product and limestone have a 1:1 molar relationship.

#"Moles of calcium carbonate"=(500xx10^3*g)/(100.09*g*mol^-1)=5.00xx10^2*mol#

The formula for "Mass of calcium oxide" is 5.00x10^3molxx56.08g*mol^-1.

#=280.1xx10^3*g-=280# #"kg"#
For what would we typically use this quantity of #"quicklime"#?

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
