Answer:

No.

Energy cannot be created nor destroyed, it changes form.

Explanation:

Energy is collected by eukaryotes through chloroplasts which is converted to glucose and goes through ATP.

Answer:

We can see that the energy and mass are transformed in other forms via cellular respiration and photosynthesis. Plants breathe carbon dioxide and expel oxygen.

Explanation:

Photosynthesis is where a plant takes light from the sun, water from the soil, and carbon dioxide from the air, and turns it into two things: glucose, which it uses for energy, and oxygen, which it releases into the air. ... Matter and energy is neither created nor destroyed, so it all has to go somewhere

hehe

If the heating curve is reversed, what describes the boiling point?
GalinKa [24]
Boiling is the process of converting a substance from liquid state to gaseous state. If the heating curve is reversed, the process also is reversed from converting gaseous state to liquid state. In this case, the reverse of boiling is condensation. So the answer is point of condensation.

Calculate the solubility of zn(oh)2(s) in 2.0 m naoh solution. (hint: you must take into account the formation of zn(oh)2−4, whi
Brilliant_brown [7]
When we have:

Zn(OH)2 → Zn2+ 2OH-  with Ksp = 3 x 10 ^-16

and:

Zn2+ + 4OH- → Zn(OH)4 2-  with Kf = 2 x 10^15
 
by mixing those equations together:

Zn(OH)2 + 2OH- → Zn(OH)4 2- with K = Kf *Ksp = 3 x 10^-16 * 2x10^15 =0.6

by using ICE table:

         Zn(OH)2 + 2OH- → Zn(OH)4 2-

initial                     2m              0

change                  -2X                +X     

Equ                       2-2X                 X

when we assume that the solubility is X

and when K = [Zn(OH)4 2-] / [OH-]^2

        0.6 = X / (2-2X)^2    by solving this equation for X

∴ X = 0.53 m

∴ the solubility of Zn(OH)2 = 0.53 M

The energy released from 1 gram of uranium is more than 1 million times greater than the energy released from 3 grams of coal. T
SVEN [57.7K]

The energy released from 1 gram of uranium is more than 1 million times greater than the energy released from 3 grams of coal is True.

<u>Explanation:</u>

Nuclear Fission is the process in which splitting of a nucleus takes place that releases free neutrons and lighter nuclei. The fission of heavy elements like "Uranium is highly exothermic" and releases "200 million eV" compared to the energy that is released by burning coal which gives a few eV.

In the given example, it is obvious that the energy released from 1 gram of uranium is more than that of the energy released from 3 grams of coal because the amount of energy released during nuclear fission is millions of times more efficient per mass than that of coal considering only \frac{1}{10}^{th} part of the original nuclei is converted to energy.
