How do you balance C2H6 O2-CO2 H₂O?

Answer 1

First balance Carbon (add 4 at right side, 4=4)

C4H10 --> 4 CO2 + H2O

Then balance Hydrogen (add 5 at right side, 10=5*2 )

C4H10 --> 4 CO2 + 5 H2O

Then balance Oxygen (add 6.5 O2 at left side, (4*2 + 5)right = 13 = (6.5*2)left

C4H10 + 6.5 O2 --> 4 CO2 + 5 H2O

Multply both siide by 2 to prevent halved quantities

2 C4H10 + 13 O2 --> 8 CO2 + 10 H2O

Answer 2

There is no way to balance that, because no matter how you group the molecules you're either creating oxygen atoms or destroying hydrogen atoms.We can fix that problem by assuming there's also oxygen present as a reactant and the water and carbon dioxide are products.
This is an extremely simple equation to balance, by the way, you should be able to do it trivially by accounting for the carbon and hydrogen and then working out how much oxygen you need.

Each butane (C4H10) has 4 carbon atoms, and will produce four CO2 molecules (using four O2 molecules to do so).

Each butane has 10 hydrogen atoms, and will produce five H2O molecules, using ... er ... okay, it's a LITTLE more complicated ... two and a half O2 molecules to do so. To fix this "half molecule" problem, we just multiply everything by two, and come up with

2 C4H10 + 13 O2 -> 10 H2O + 8 CO2

Checking, that's 2x4 = 8 carbon on the left and 8x1 = 8 carbon on the right, so that's good.

Hydrogen: 2 x 10 = 20 and 10 x 2 = 20 ... also good.

Oxygen: 13 x 2 = 26 and (10 x 1 = 10 plus 8 x 2 = 16) = 26.

Everything balances, so that must be the right equation.

Answer 3

The balanced chemical equation for the combustion of ethane (C2H6) with oxygen (O2) to form carbon dioxide (CO2) and water (H2O) is:
C2H6 + 7O2 -> 2CO2 + 3H2O

Answer 4

the balanced equation is 2_C7H6O2+15_O2-->14_CO2+6_H2O

Answer 5

2 C2H6 + 7 O2 → 4 CO2 + 6 H2O

Every thing balanced first but O2. Leave that for last.

Answer 6

2C2H6 + 7O2 -> 4CO2 + 6H2O

Watch the carbohydrate and balance oxygen last.

Answer 7

(C4H10O)l + 6(O2)g = 4(CO2)g + 5(H2O)l

Answer 8

c3h6+o2---co2+h2o

Answer 9

2c2h6 + 7o2 -> 4co2 + 6h2o

Answer 10

2C2H6 + 7O2 -> 4CO2 + 6H2O
