What best explains the formula unit for a compound made from fluorine and hydrogen? 1. HF, because fluorine is short of one electron, and hydrogen is in excess of one electron
2. HF, because both fluorine and hydrogen are capable of forming only one covalent bone
3. H2F, because fluorine is short of two electrons, and hydrogen is short of one electron
4. H2F, because fluorine is capable of forming one, and hydrogen is capable of forming two covalent bonds

2)HF bcz both fluorine and hydrogen are capable of forming only one covalent bond

Explanation:

flourine is short one electron to become stable while hydrogen has only one electron.Hydrogen cant give out its one electron fully thus it will share its one electron with flourine

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
