Answer:
16G = 1 mole ; then 4G = how many moles? 4/16 = 0.25 mole; That means 4 grams of oxygen is 0.25 moles.
It would be C, 6.2 x 10^23.
Avogadro's number, or, the mole, is 6.02 x 10^23. Although the grams and molar mass of an element may be different, every element must have the same amount of atoms to obey avogadro's number.
Since no choices are given, I will describe the reactivity of the element chlorine. A halogen is example of
nonmetal. When compounds containing halogens they are
called salts thus the name “salt – former”. Halogen consists of Fluorine,
Chlorine, Bromine, Iodine, Astatine. An example of is reactivity is the monochlorination of
an alkane, which involves substituting one of the hydrogen atom in the alkane and
exchange it with a chlorine atom.
CH₄ + Cl₂ → CH₃Cl + HCl
The H in methane is substituted with the
Cl in chloride.
