32. Which of the following chemical equations is balanced correctly?

A) C6H6 + O2 - 2CO2 + 3H2O
B) Cs2 + 3CI2 - CCI4 + S2CI2
C) B2O3 + 2C - B4C + CO
D) CI 2 + NaI - 2NaCI + I2

1 answer

To determine which of the provided chemical equations is balanced correctly, let's analyze each one:

A) C6H6 + O2 → 2CO2 + 3H2O

  • Reactants: 6 C, 6 H, and 2 O (from O2)
  • Products: 4 C (from 2CO2) + 6 H (from 3H2O) + 4 O (from 2CO2) + 3 O (from 3H2O) = 4 C + 6 H + 7 O

This equation is NOT balanced.

B) Cs2 + 3Cl2 → CCl4 + S2Cl2

  • Reactants: 2 Cs and 6 Cl
  • Products: 1 C + 4 Cl (from CCl4) + 2 S + 2 Cl (from S2Cl2) = 1 C + 2 S + 6 Cl

This equation is NOT balanced.

C) B2O3 + 2C → B4C + CO

  • Reactants: 2 B, 3 O, and 2 C
  • Products: 4 B (from B4C) + 1 O (from CO) and 1 C (from CO) = 4 B + 1 O + 1 C

This equation is NOT balanced.

D) Cl2 + NaI → 2NaCl + I2

  • Reactants: 2 Cl and 1 I (from NaI)
  • Products: 2 Na (from 2NaCl) + 2 Cl (from 2NaCl) + 2 I (from I2) = 2 Na + 2 Cl + 2 I

This equation is NOT balanced.

From the analyses, none of the provided equations are balanced correctly. If further corrections or clarifications about each equation are needed, please let me know!
