Below is the equation of sucrose and sulfuric acid-producing carbon, water vapor and sulfur dioxide.

c12h22o11(s) + h2so4(aq) + 1/2 o2(g) → _c(s) + co2(g) + 12h2o(g) + so2(g)

what coefficient of _c(s) would balance this equation?

11 is the coefficient for C to balance the equation

Explanation:

C₁₂H₂₂O₁₁(s)  +  H₂SO₄(aq)  +  1/2 O₂(g)   → 11C(s) + CO₂(g) + 12H₂O(g) + SO₂(g)

12 Carbons in left side   →   12 Carbons in right side

12 in sucrose → 11 in solid C + 1 in the CO₂

24 Hydrogens in left side → 24 Hydrogens in right side

22 in sucrose + 2 in sulfuric → 24 in water vapor

1 S in left side → 1 S in right side

1 S in sulfuric → 1 S in sulfur dioxide

16 O in left side → 16 O in right side

11 O in sucrose + 4 in sulfuric + 1 O at ground state → 2 O in carbon dioxide + 12 in water vapor + 2 in sulfur dioxide

elements make up everything, and they combine to make compounds.

the answer is c

i think it's c. if you look search electronic symbol on google and then click on wiki it shows you a
