Question

When the following equation is balanced with the lowest whole number coefficients possible, what is the coefficient in front of \(O_2\)?

\(C_3H_{8~(g)} + O_{2~(g)} \rightarrow CO_{2~(g)} + H_2O_(g)\)

1
3
5
8

Answer 1

So u know how to balance?

Answer 2

kind of

Answer 3

So first try to balance the equation..

Answer 4

???

Answer 5

sorry my mom got home and she wanted me to try something one

Answer 6

*on

Answer 7

\(\sf C_3O_{2~(g)}+H_8O_{(g)}\)?

Answer 8

C3H8 + 5 O2 = 3 CO2 + 4 H2O

Answer 9

Can u find the correct option now?

Answer 10

Where is the \(\sf 5~O_2\) from?

Answer 11

O2 is given in the equation.

Answer 12

yeah but you have 5 O2
