What happens when sodium reacts with fluorine to produce sodium

Balanced chemical reaction: 2Na(s) + F₂(g) → 2NaF(s) + energy.

This is exothermic reaction (energy or heat is released), because reactants have higher energy than products of reaction.

In ionic salt sodium fluoride (NaF), fluorine has electronegativity approximately χ = 4 and sodium χ = 1 (Δχ = 4 - 1; Δχ = 3), fluorine attracts electron and it has negative charge and sodium has positive charge.

i believe the answer is 5,000

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.
