Burn propane c3h8 write the balanced equation

C3H3 is the molecular formula of propane.

When it is burned with oxygen result in the production of CO2.

Reaction is given as follow

C3H8 + 5O2 ---> 3CO2 + 4H2O.

The balance equation shows that 1mole of propane reacts with 5mole of oxygen results in the formation of 3 mole of carbon dioxide and 4 mole of water.

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.
