 $ (a){C_6}{H_{12}}{O_6} \\
  (b){H_2}S{O_4} \\
  (c)HN{O_3} \\
  (d)CaC{O_3} \\ $
Also name these compounds.

Answer 1

Hint: The atom is the tiniest unit of matter that may be divided without releasing electrically charged particles. It's also the smallest unit of matter with chemical element properties.

Complete answer:
 $ (a){C_6}{H_{12}}{O_6} $ ​ : This compound has atoms of $ C $ which represents carbon, $ H $ which represents hydrogen and $ O $ which represents oxygen. It has $ 6 $ atoms of the element Carbon, $ 12 $ atoms of the element hydrogen and $ 6 $ atoms of the element oxygen.
The name of this compound is Glucose.
 $ (b){H_2}S{O_4} $ : This compound has atoms of $ H $ which represents hydrogen, $ S $ which represents sulphur and $ O $ which represents oxygen. It has $ 2 $ atoms of the element hydrogen, $ 1 $ atom of the element sulphur and $ 4 $ atoms of the element oxygen.
The name of this compound is Sulphuric acid.
 $ (c)HN{O_3} $ : This compound has atoms of $ H $ which represents hydrogen, $ N $ which represents nitrogen and $ O $ which represents oxygen. It has $ 1 $ atom of the element hydrogen, $ 1 $ atom of the element nitrogen and $ 3 $ atoms of the element oxygen.
The name of this compound is Nitric acid.
 $ (d)CaC{O_3} $ ​ : This compound has atoms of $ Ca $ which represents calcium, $ C $ which represents carbon and $ O $ which represents oxygen. It has $ 1 $ atom of the element calcium, $ 1 $ atom of the element carbon and $ 3 $ atoms of the element oxygen.
The name of this compound is Calcium Carbonate.

Additional Information:
Protons, neutrons, and electrons are the three fundamental subatomic particles that make up an atom. The nucleus of each and every atom is made up of protons and neutrons, with electrons orbiting around it.

Note:
The simplest chemical substances are elements, which are made up of identical atoms. Compounds are chemical compounds made up of two or more elements linked together chemically in a certain ratio.
