Acids in which the amount of water is more are called organic acids​

Answer 1

Answers + Explaination

1. (a) Basic substance

two substances which contains bases are known as basic substances while those which contain acid are known as acidic substances. Of both acis and base are present in equaly amount then such substances are neutral substances

2. (c) H2SO4

Given , about formula belongs to the sulphuric acid. It is highly corrosive in nature as well as very strong acid too.

5. C) Radiation

The most easiest way of transfer of heat is through radiation why other two processes that is conduction and convection requires matter in order to transfer heat.

4.(d) Joule

Heat is the non mechanical form of transfer of energy and it's SI unit is Joule named after a famous scientist.

Answer of T/F

Such acids which contain more amount of water are known as dilute acids. While organic acids are weak acids which basically are made up of carbon and hydrogen. Such acids carbonic acid and formic acid they are very less or almost no corrosive in nature. While strong acids like hydrochloric acid and sulphuric Acid are very dangerous and can cause serious harm if if they come in contact with any substance in their concentrated state.
