- Is that writing and balancing chemical equations, Mrs. Reyes?
- Isn't it hard?
- Yes, it is!
- Good morning class! Today we will tackle the important steps in solving the formula mass of a compound.
- It will only get hard when you don't listen to our lesson carefully. So here's our first example. Step 1: Convert the given problem into a word equation. Can you try it, Jobhelle?
- Yes, ma'am! Magnesium + Nitrogen gas -> Magnesium Nitride
- "Magnesium reacts with Nitrogen gas to produce Magnesium Nitride."
- Good job! Next, Step 2: Convert the word equation into a chemical equation. Please try it, John.
- Mg + N2 -> Mg3N2
- Mg= 1x3=3 Mg=3 N=2 N=2
- 3Mg + N2 -> Mg3N2
- Well done! For the last one, Step 3: Balance the given chemical equation written in the Step 2 by adding coefficient after the chemical symbol or chemical formula. Can you guys make it?
- I love balancing. General chemistry is now my favorite!
- I thought balancing chemical equation is difficult because of the series of letters and numbers. But I realized that it is just easy with those simple steps.
- Very good class! Do you have something to say before we end our discussion?
- Me! Yey!!!
- Very well said! I'm happy to know that everyone's learning. Now, who wants ice cream? My treat!
