On Thursday, we began looking at how we can use our knowledge on reaction types to predict the products of a chemical reaction. Knowing what the reactants are, we can then identify what type of reaction will occur and use that to predict the likely products. Sometimes however, reactions don't occur. This only happens in specific situations with single replacement and double replacement reactions.
In a single replacement reaction, in order for a reaction to occur, the element doing the replacing has to be more active than the element that is being replaced. Activity is determined by looking at where the element is located on an activity series. We finished the lesson on Thursday by working on Assignments C13 and C14.
On Friday, we started looking at double replacement reactions and determining whether or not a reaction will occur. This involved using another table called a solubility table to determine whether or not a compound was soluble in water. We went through how to use this table and did a couple of examples to determining solubility. We didn't quite get to assignment C15, but we will on Monday.
