Question

Give the name of the elements present in the following compounds.
A.Quick lime
B.Hydrogen bromide
C.Baking Bromide
D.Potassium sulphate

Answer 1

Hint: We have to write the name of elements present in the compound which is given in the question. Therefore, we must know the chemical formula of the given compounds. Also, we can distinguish these compounds by discussing their uses and properties.

Complete step by step solution:
a) We must know that quick lime is known as calcium oxide with chemical formula $CaO$. It has calcium and oxygen as its main elements. Quicklime has a wide range of uses in many industries like it is used in the production of metal and steel, pulp and paper. It is also used in the treatment of water and harmful gases and in the mining industry to suffice the dust.
 b) We can write the hydrogen bromide as \[HBr\] in terms of its chemical formula. It has hydrogen and bromine elements as clearly seen in its formula at equal constant. Hydrogen bromide and hydro bromic acid together is produced by combining hydrogen atoms and bromine atoms at temperatures between 200 and 400 °C approximately. The reaction is initially catalysed by platinum or asbestos.
c) We must know that the baking powder is sodium carbonate, which can write as \[NaHC{O_3}\] in its chemical formula. There are many elements present in it which are sodium, hydrogen, carbon and oxygen. We know that baking powder is used to increase the volume and maintain the structure and texture of baked eatables.
d) We can write the chemical formula of Potassium sulphate as \[{K_2}S{O_4}\] in chemical formula. Potassium, sulphur and oxygen are the naturally occurring elements found in \[{K_2}S{O_4}\].hence it is one of the plant growth regulators. Potassium sulphate is the suitable compound for specific kinds of crops. Thus, it is used to help in growing some types of fruits, vegetables, and tobacco.


Note: We must understand that quicklime $CaO$ is used in daily household works and with the demand increasing in its production; industrial revolution is taking place with proper enumeration using it.
