The fluoride ion reacts with water to produce HFHF. Part A Write out the chemical equation for this reaction. Express your answer as a chemical formula. Include the physical states.

The chemical reaction is ;

Explanation:

The chemical reaction of formation of hydro fluoric acid  by reaction of fluoride ions and water is given by :

According to reaction, when 1 mole of fluoride ions react with 1 mole of water they give hydro fluoric acid  and hydroxide ions as product.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
