Look at the CHEMICAL EQUATION below... 6H2O + 6CO2 → C6H12O6 + 6O2

Identify the elements used and how many atoms of element are present in the equation.

ELEMENTS # OF ATOMS ELEMENTS # OF ATOMS

1. 1.

2. 2.

3. 3.

H=12

O=6+12=18

C=6

and the equation is balanced

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 number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
