The balanced equation

6CO₂ + 6H₂O = C₆H₁₂O₁₆ + O₂

Given

Reaction

CO2 + _H2O = _C6H12O16 + _O2

Required

Balanced equation

Solution

Give a coefficient

aCO₂ + bH₂O = C₆H₁₂O₁₆ + cO₂

Make an equation

C, left = a, right = 6⇒a=6

H, left = 2b, right = 12⇒2b=12⇒b=6

O, left=2a+b, right = 16+2c⇒2a+b=16+2c⇒2.6+6=16+2c⇒2c=2⇒c=1

The equation becomes :

6CO₂ + 6H₂O = C₆H₁₂O₁₆ + O₂

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
