Respuesta :
The given degradation reaction of sodium carbonate is balanced equation. Option C is correct.
Balanced Equation:
It is the chemical equation in which the molar ratios are written correctly to balance consumed reactant and product that formed in the reaction.
For example-
[tex]\bold { Na_2CO_3(s)\rightarrow Na_2O(s)+2CO_2(g) }[/tex]
Here, before the reaction, there are 2 sodium atoms, 1 carbon, and 3 oxygen atoms. After the reaction (In product), the number of atoms is also the same.
Therefore, the given degradation reaction of sodium carbonate is balanced equation.

Answer:
D
Explanation:
The first half of the equation has 4 Al and 6 O. The second half has 4 Al and 6 O.
B wouldn't work because the first half has 2 Zn, 2 S, 2H, and 2 Cl, but the second half has 4 Zn, 1 S, 2 H, and 8 Cl. The first and second half of the equation must be equal.
