Balance the following reaction. Leave the box empty if no other coefficient is needed. C2H5 + O2 → CO2 +H2O
Mariulka [41]

Answer: -

4C₂H₅ + 13 O₂ → 8 CO₂ + 10 H₂O

Explanation: -

The given equation is

C₂H₅ + O₂ → CO₂ + H₂O

Balancing for H,

2C₂H₅ + O₂ → CO₂ + 5H₂O

Balancing for C

2C₂H₅ + O₂ → 4CO₂ + 5H₂O

Now right hand side we are getting 13 O which is an odd number.

In order to balance O, we first try to even out the number of O on right side by multiplying whole equation by 2.

4C₂H₅ + 2O₂ → 8CO₂ + 10H₂O

Now balancing for O

4C₂H₅ + 13 O₂ → 8 CO₂ + 10 H₂O

Describe the steps used to create Lewis dot structures to represent covalent bonds.
antiseptic1488 [7]
1)Identify the atoms that are participating in a covalent bond.
2)Draw each atom by using its element symbol. The number of valence electrons is shown by placing up to two dots on each side of the element symbol, with each dot representing a single valence electron.
3)Predict the number of covalent bonds each atom will make using the octet rule.
4)Draw the bonding atoms next to each other, showing a single covalent bond as either a pair of dots or a line representing a shared valence electron pair. If the molecule forms a double or triple bond, use two or three lines to represent the shared electron pairs, respectively.
