Which of the following chemical equations is balanced correctly?

a
2Al + Fe2O3 -> Al2O3 + Fe



b
4CaO + 10C -> 4CaC2 + 2CO2

c
B2O3 + 2C -> B4C + CO2



d
SO3 + H2O -> H2SO3

The correct answer is d) SO3 + H2O -> H2SO3.

wrong

I apologize for the incorrect response. Upon reviewing the options, the correctly balanced chemical equation is c) B2O3 + 2C -> B4C + CO2.
