Write the composition of the following materials by means of chemical formulae and classify them accordingly of Brass
Answers
Answer:
1 . Water - H2O - It is in Liquid state .
2 . Carbon - C - It is in Solid state .
3 . Oxygen - O2 - It is in Gaseous state .
4 . Air - There is no molecular formula of air . Therefore , we write chemical composition of air :
i) Nitrogen - 78%
ii) Oxygen - 20.9%
iii) Carbon Dioxide - 0.03%
iv) Inert Gases - 0.98%
v) Water Vapour - 0.1%
5 . Aluminium - Al - It is in Solid state .
6 . Brass - CuPbZn - It is in Solid state .
7 . Carbon Dioxide - CO2 - It is in Gaseous state
