Mg(NO_{3})_{2} + K_{2}CO_{3} -> MgCO_{3} + KNO_{3} Mg(NO_{3})_{2} + K_{2}CO_{3} -> MgCO_{3} + 2KNO_{3} 2Mg(NO_{3})_{2} + K_{2}CO_{3} -> 2MgCO_{3} + KNO_{3} Mg(NO_{3})_{2} + 2K_{2}CO_{3} -> MgCO_{3} + 2KNO_{3}
I am hesitating between 4 options to answer the following question, which option should I choose?
Question: Examine each of these chemical equations to determine which equation is correctly balanced.
Possibilities:
- Mg(NO_{3})_{2} + K_{2}CO_{3} -> MgCO_{3} + KNO_{3}
- Mg(NO_{3})_{2} + K_{2}CO_{3} -> MgCO_{3} + 2KNO_{3}
- 2Mg(NO_{3})_{2} + K_{2}CO_{3} -> 2MgCO_{3} + KNO_{3}
- Mg(NO_{3})_{2} + 2K_{2}CO_{3} -> MgCO_{3} + 2KNO_{3}

Mg(NO_{3})_{2} + K_{2}CO_{3} -> MgCO_{3} + 2KNO_{3}
