5. What mass calcium oxide can be made when 4.72 g of limestone (calcium carbonate) is decomposed by heating? __CaCO3(s) →__CaO(s) +
__CO2(g)

What volume of carbon dioxide will be formed from decomposing 356 g of calcium carbonate?

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.

um i think it might be a car?
