Where do I find acids and alkalis?
Lots of everyday substances contains acids or alkalis:
Acids are found in:
citrus fruits (lemon juice, orange juice)
vinegar
car batteries (sulphuric acid)
your stomach (hydrochloric acid)
Rainwater is a little acidic, but pollution (e.g. sulphur dioxide) from burning fossil fuels may make it even more acidic, forming acid rain.
When acids are present in food, they usually taste sour (think of the taste of lemon juice or vinegar). Strong acids are very dangerous.
Alkalis are found in:
oven cleaner (sodium hydroxide)
soap
cleaning fluid e.g. spray-and-wipe (ammonia)
Notice the connection between these substances? Alkalis are often found in substances for cleaning.
Strong alkali substances are just as dangerous as strong acidic substances, causing very serious burns if they come into contact with your skin.

Acid - vinegar, citric fruit juices - and of course, cola. Just look at what it does to copper coins or pieces of meat!
Alkalis - Bleach, soap and detergents^^

It is an exothermic reaction. FYI: A reaction that takes in heat and causes the beaker to become cooler would be an endothermic reaction.
