I will give Brainliest please help. :( The given equation represents a chemical reaction occurring in plants. Does this chemical equation show Conservation of Mass?

Conservation of mass occur when your chemical equation is balanced.

So let's see if it is balanced:

6CO₂ + 6H₂O > C₆H₁₂O₆ + O₂

You need to have the same quantity of atoms of each element on the product side and reactant side.

Reactant side: 6CO₂ + 6H₂O

Product side: C₆H₁₂O₆ + O₂

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.

if you're asking what comes out, it's steam.
