We can say that oxides peroxides and super oxides of groups. One A and two A are reactive compounds. Now, they can react with water to produce hydroxides which are basic in nature and they react with acids to produce salts and water. If we take a look here, if we ever reacting with water, we have lithium oxide reacting with liquid water. It produces lithium hydroxide base. We put a two here to balance it out reacting with acids. Here we have calcium oxide solid reacting with hydrochloric acid that produces our salt in the form of calcium chloride and liquid water. To balance this, we put a two with the hydrochloric acid. So just remember when it comes to these oxides, we can react them with water to create bases as a product or we can react them with wa with acids to create water. And an ionic compound called a salt.

Here, it says complete and balance the following equation. Here, we have lithium oxide reacting with hydrochloric acid. We know that when we're reacting with an acid, we're gonna create water and a salt. So here, lithium oxide is composed of lithium ion and the oxide ion hydrochloric acid is made up of H plus ion and chloride ion. The lithium and chlorine chloride will combine together to give us our salt. So lithium chloride, it's aqueous the oxide and the hydro ion H plus combine to give us our liquid water to balance this, we need to put a two here so that both sides have two lithiums. But now we have two chlorine on the product side. So I put a two here. This here would represent our balanced overall equation between the reaction of lithium oxide solid and hydrochloric acid.
