Answer:

C. NaHCO3 → Na2CO3 + H2O + CO2

Explanation:

» For a balanced equation, the number of atoms of reactants and products must be equal.

» In equation C, the reactant side has one sodium atom while ptoduct side has 2 sodium atoms.

» The balanced equations mus be;

[tex]{ \rm{ 2NaHCO _{3(aq)} → Na _{2}CO _{3(s)}+ H _{2} O _{(l)} + }CO _{2(g)} }[/tex]

Answer:

Option C

Explanation:

Let's balance that

[tex]\\ \tt\hookrightarrow 2NaHCO_3\longrightarrow Na_2CO_3+H_2O+CO_2[/tex]

On reactant side

  • Na=2
  • H=2
  • O=6
  • C=2

On products side

  • Na=2
  • H=2
  • O=6
  • C=2
