Answer:
1) acid + base = salt + water its neutralization reaction
2)A solution that is neither acidic nor basic is neutral and has a pH of 7. The pH scale, which ranges from 0 to 14, indicates how acidic or basic a substance is. A substance that has a pH below 7 is and acid and a substance with a pH above 7 is a base.
3)Self raising flour rises due to the baking powder inside.
Self raising flour is different from normal flour as it has baking powder mixed inside already. Baking powder is usually made up of a chemical called sodium carbonate, when mixed with water this will releases the gas carbon dioxide. So when you mix a cake together and pour it into a tin, the heat plus the water in the mixture will cause the baking powder to release small amounts of carbon dioxide which produces bubbles. These bubbles try to rise up and so the mixture starts to rise with all the tiny bubbles. The reason the air does not escape is because the heat from the oven is making the cake solid. Once is it solid the carbon dioxide slowly leaves the bread or cake, so don’t worry you’re not eating loads of carbon dioxide
4) They react/break down organic chemicals like oil/grease without attacking the metals that they are attached too which is better than acids which do react with metals as well
5) it is because when you vomit due to acidity in stomach
the harsh acid creates a burning sensation in the back of your throat and chest, and can also give you a sour or bitter taste in your throat and mouth
