| A | B |
|---|
| a reaction that can go in both directions | reversible reaction |
| reversible reaction equations use this sort of arrow | double arrow |
| a reaction that gives out energy | exothermic |
| a reaction that takes in energy | endothermic |
| what happens to the temperature in an endothermic reaction? | it decreases |
| What happens to the temperature in an exothermic reaction? | it increases |
| The energy transfer in a reversible reaction | is the same in both directions |
| Pink cobalt chloride crystals are | hydrated |
| White copper sulphate powder is | anhydrous |
