Compare metals to nonmetals. Include where they are located on the periodic table as well as three properties of each.

Difference between metals and non metals.

1) Metals are good conductors of heat and electricity while non metals are poor conductors.

2) Metals are hard while non metals are soft.

3) Metals have shiny surface while non metals have not.

Examples of metals are sodium and iron while non metals are chlorine and oxygen.

Location in the periodic table.

Metals are present on the left side of the table while non metals are present on the right side of periodic table.

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.

let that person have a turn to speak : )
