Answer:
Below in Bold
✧ 
♨ The word ' acid ' is derived from the Latin word ' acidus ' which means sour. An acid is defined as the substance which gives hydrogen ions or protons ( H+ ) when dissolved in water. For example :
- Hydrochloric acid
- Sulphuric acid
- Nitric acid
- Carbonic acid
- Acetic acid
✎ 
☃ Physical properties :
- Acids have a sour taste. But some acids like steric acid, boric acid , salisylic acid do not have a sour taste. Laboratory acids are more corrosive , so they are dangerous to taste.
- Acid turn blue colour of litmus paper into red and light yellow methyl orange into red. They make phenolphthalein colourless.
☂ Chemical properties :
- Acids have a high dissolving power and dissolve many substances. Some metals like zinc and magnesium react with acids like dilute sulphuric acid and dilute hydrochloric acid to produce salt and hydrogen gas.
- Acid react with base to give salt and water.
- Acid gives H+ ions when dissolved in water.
- Acid react with metallic carbonates to produce carbon dioxide.

Answer:
The advantages of fossil fuels are that they are abundant and accessible, they provide a large amount of concentrated energy, they are relatively low cost and they can be transported relatively easily.
Explanation:
I got it from Google and Google is always right lol
.
Density is defined as the ratio of mass and volume. The formula of density is:
-(1)
Density of milk =
(given)
Volume of milk =
(given)
Substituting the values in formula (1):



Hence, the mass of the milk is
.
