Propane C3H8(g) can be burned in pure oxygen to give only carbon dixoide and water.?

Question

When the equation is properly balanced with the smallest ratio of integer coefficients, which of the following statements are true ?
(For statement e, assume the amount of given reactant reacts completely.)
a) The coefficient of propane is 1

b) The coefficient of oxygen is 5

c) The coefficient of carbon dioxide is equal to that of oxygen

d) The coefficient of water is four fifths that of oxygen

e) 4 mole of propane produces 16 mole of water

f) 4.5 mole of oxygen reacts with 0.9 mole of propane

Answer 1

Let's see

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

yeah he's ^^ right!

Answer 2

a) True
b) True
c) False
d) True
e) True
f) True

Answer 3

C3H8 -+502 -->3CO2 + 4H20
a. true
b. true
c.false
d.true
e. true
f. this is weird. if you round 4.5 it's 5, which is the coefficient of oxygen. and if you round .9 it's 1 which is the coefficient of the propane. so true?? i guess. dunno.
