Question

When asked to balance the equation:
C2H6 + O2 = CO2 + H2O
the following suggestions were made:
C2H6 + 5O2 = 2CO2 + 3H2O
C2H6 + 5O = 2CO + 3H2O
2C2H6 + 7O2 = 4CO2 + 6H2O
Which answer is correct and what is wrong with the others?

Answer 1

In the first answer, how many carbon atoms on the left side?

Answer 2

2

Answer 3

@Mertsj

Answer 4

how many carbon atoms on the right side?

Answer 5

the number of each atom must be equal on each side of the equation remember law of conservation of mass

Answer 6

ok

Answer 7

so..which one of these answers is correct?

Answer 8

@1stwilight before I help you out can you tell me which one you think it is and why?

Answer 9

@15Twilight

Answer 10

It looks like all of them are correct

Answer 11

but I know that's not right

Answer 12

@15Twilight follow this

to see whether an equation is balanced make a chart. and count up the number of each atom in both the reactants and the products.

C2H6 + O2 = CO2 + H2O



based of of this is the equation balanced?

Answer 13

no

Answer 14

good. for your reference always do that in the future

Answer 15

we need to balance this now, this takes time and there's no real i guess strategy you just have to try your best to put coefficients infront of the reactants+ products to balance them.

Answer 16

C2H6 + 4O2 = 2CO2 + 3H2O

Answer 17

2 atoms of carbon
6 atoms of hydrogen,
8 atoms of oxygen

products:
2 atoms of carbon
4 atoms of oxygen,
and 6 atoms of hydrogen

..am I right?
