Explain in your own words, what is happening with the ions in the precipitate reaction shown in the video example. Potassium Iodide is added to Lead Nitrate. -Write an equation

-Write a net ionic equation

- Discuss and identify cations, anions, precipitates, and spectator ions from the reaction in the video

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.

the answer is d.) potassium
