How many grams of carbon are In 25 g of CO2?

44 grams of carbon dioxide contains 12 grams of carbon 1 gram of carbon dioxide contains 12/44 grams of carbon 25 grams of carbon dioxide contains 300/44 grams of carbon •Hence, 25 grams of carbon dioxide contains 6.818 grams of carbon

Explanation:

d. temperate deciduous forest

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.
