- Hey Marie, do you still remember our lesson yesterday? About the physical and chemical changes in matter?
- Yes! I love it. I', quite amused by these changes in matter.
- In connection to yesterday's lesson, our lesson to today is about Writing and Balancing different Chemical Equations
- In conclusion, The method of representing a chemical reaction with the help of symbols and formula of the substances involved in it is known as a chemical equation.
- Marie, do you know how to solve example 5? The situation is Magnesium reacts with Nitrogen gas to produce magnesium nitride.
- Sure I can help you with that. Convert the situation into a chemical equation first.
- Balance the given chemical equation by adding coefficient after the chemical symbol or chemical formula.
- So if I consider the coefficient of the product and the reactant, I would only get a 3 in the Magnesium?
- Yup, that's about it. Three molecules of Magnesium react with a Nitrogen gas yields 1 molecule of Magnesium Nitride. Do you know it now? Come on, I'm hungry.
- It's clear to me now. Thank you. By the way, lunch will be my treat.
