What are the names of the compounds kcio3 and h2so4 respectively

Then name of the compound KCl is Potassium Chlorate and S is Sulfuric Acid.

Explanation:

Here our first compound is KCl  which contains potassium, chlorine and oxygen atoms. It is a white crystalline substance.

                                             S is Sulfuric acid which contains sulfur, oxygen and hydrogen. It is also known as Vitriol.

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.
