Question

Which of the following chemical equations depicts a balanced chemical equation?

OA. 2Na₂CO3 + 3HCI-> 3NaCl + 2CO₂ + H₂O
OB. Na₂CO3 + HCl-> 2NaCl + CO₂ + 2H₂O
OC. Na₂CO3 + HCl-> NaCl + CO₂ + H₂O
OD. Na2CO3 + 2HCl-> 2NaCl + CO2 + H₂O

Answer 1

In order to find a balanced equation in this question, we need to look at a reaction that presents the same number of the same elements on both sides of the reaction, and the option that presents this is:

Na2CO3 + 2 HCl -> 2 NaCl + CO2 + H2O
