32
what is a base
a metal oxide is known as a base
33
what is an Alkali
the opposite of an acid and it is also the solution that is formed when a soluble metal base is dissolved in water
34
what is a salt
a compound formed when a metal reacts with an acid
35
what is an exothermic reaction and what will happen
a reaction which gives out energy and so the temp goes up, it will be hot
36
what is the Law of conservation
energy cannot be created or destroyed
37
what is an endothermic reaction and what will happen
a reaction that takes in energy and so the temp goes down, it will be cold
