Students will reinforce predicting and balancing chemical equations AND THEN THEY NEED TO START WRITING THE SKELETON EQUATIONS INTO WORDS. Example: 2NaOH + (1)H2SO4 → (1)Na2SO4 + 2H2O. In words, this is expressed as: Two molecules of sodium hydroxide combine with one molecule of sulfuric acid ( or one molecule of hydrogen sulfate) to yield one molecule of sodium sulfate and two molecules of water.
Note that instead of using the word “combine”, you can also use “react” or “join”. Do not use the word “plus” to describe “+ sign” since you are not adding numbers; you are carrying out a chemical reaction. Furthermore, use the conjunction “and” to represent the “+ sign” in the products since it means “also produced” in a reaction.
Moreover, other terms besides “to yield” can be used to represent the arrow such as “to make”, “to produce”, or “to result in”.
Students will do #’s: 64, 65, & 66 on page 312 as practice on writing word equations.
