3. Nickel replaces silver from a solution of silver nitrate according to the following reaction: 1 Ni + 2 AgNO3 → 2 Ag + 1 Ni(NO3)2

If you have 22.9 grams of Ni and 112 grams of AgNO3 which reactant is the limiting and
excess reactant? How many grams of nickel (II) nitrate are formed?

Limiting Reactant -

Excess Reactant -

Mass of Ni(NO3)2 -

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.
