for example if hydrogen combines with oxygen to form water, the property of hydrogen differs from oxygen and also both differs chemically when compared to water.
D liquid water turning into caper
Molar mass of CHCl3 is
sum of atomic mass of all the atoms in it.
= C + H + 3 Cl
= 12.0107 + 1.008 + 3 (35.453) = 2.0107 + 1.008 + 106.359
= 119.38 g/mol
Molar mass of CHCl3 is 119.38 g/mol
The nonmetals, as s class of elements contains both solids and gases at room temperature.
Some gases classed as nonmetals are : hydrogen, helium, oxygen, nitrogen, fluorine, neon, or radon and many others. An example of a solid that is a nonmetal is sulfur.
