There are 8 hydrogen atoms.
4H2 actually means
A chemical bond is the force of attraction between atoms which results fro either sharing of electrons by the involved atoms or transfer of electrons. Ionic bond (involves metal and non metals and covalent bonds ( involves non metals) are the main types of bonds. Carbon-nitrogen bond involves sharing of electrons between the two atoms forming three bonds by three pairs of electrons. Bond energy is the energy that is required to break a chemical bond therefore the strength of the bond determines the amount of bond energy that can be used to break the bond.Thus as the number of electrons pair increases in the chemical bond then the bond energy increases. Therefore, the number of electrons involved in bond formation increases then the bond energy also increases

D. NH3(AQ)- base pH>7
Answer:
1386g
Explanation:
Solubility of a solute is the ability of the solute to mix into a liquid (the solvent). It measures the highest amount of substance mixed into a liquid solvent while they are both at equal amounts.
if 14g dissolved in 100cm3
the amount that will dissolve in 1000cm3 = 14 x 1000/ 100
=1400g
To form a saturated solution, 1400 - 14 = 1386g must be added.
