Aluminum sulfide will form in a reaction with 7.27 g of aluminum and 8.46 g of sulfur. How many grams of aluminum sulfide was formed with the aluminum? How many grams of aluminum sulfide was formed with the sulfur? What is the limiting reactant? What is the excess reactant?

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.

it would be d. henry moseley

hope this !

and sorry if i'm late. have a good rest of your day! : d
