Question

6) Which of the following chemical reactions is well balanced?
a) C8H16 + 16 O2 - 8 CO2 + 8 H2O
B) 3 HCl + Fe(OH)3 - 2 FeCl3 + 3H2O
C) Na2CO3 + 2 HCl - 2 NaCl + CO2 + H2O

Answer 1

Answer:

c) Na2CO3 + 2HCL ==> 2NaCl +CO2 + H2O

Explanation:

We count number of atoms

in reactants side :

Na = 2

C = 3

O = 3

H = 2

Cl = 2

in products side:

Na = 2

C = 1

O = 3

H = 2

Cl = 2
