A. Release energy
....................................
Answer:
A. it is the lowest at low temperatures
Explanation:
At low temperature the kinetic energy of a molecule is low. The kinetic energy is directly proportional to the temperature of the molecule. The kinetic energy of a molecule increases with the increase in the temperature that energize the molecules of a substance and makes them to move faster than before.
As the kinetic energy is proportional to temperature so it does not increase with decrease in the temperature (low temperature). The kinetic energy varies with the change in the temperature and it is not same at all temperature. The kinetic energy is highest at high temperature. Thus, option A is correct.
Answer:
A:The reproductive system produces hormones.
B:The reproductive system transports reproductive cells.
C:The reproductive system produces reproductive cells.
Explanation:
A:The reproductive system produces hormones. : The reproductive organs ovaries in females and testes in males produces hormones. The ovaries produce estrogen and progesterone and testes produce testosterone.
B:The reproductive system transports reproductive cells. : The ovaries in females transfers an egg into the fallopian tube and testes in males secrete sperms at the time of copulation the fertilization of egg and sperm leads to the development of zygote the precursor of new life.
C:The reproductive system produces reproductive cells.: The ovaries undergo oogenesis and in testes spermatogenesis takes place to develop egg and sperms respectively.
Explanation:
<u>Answer:</u> The solubility product of magnesium phosphate tribasic is 
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:
Given mass of magnesium phosphate = 1.24 g
Molar mass of magnesium phosphate = 262.85 g/mol
Volume of solution = 1 L
Putting values in above equation, we get:
The equation for the ionization of the magnesium phosphate is given as:
Expression for the solubility product of 
will be:
![K_{sp}=[Mg^{2+}]^3[PO_4^{3-}]^2](https://tex.z-dn.net/?f=K_%7Bsp%7D%3D%5BMg%5E%7B2%2B%7D%5D%5E3%5BPO_4%5E%7B3-%7D%5D%5E2)
We are given:
![[Mg^{2+}]=(3\times 4.72\times 10^{-3})=1.416\times 10^{-2}M](https://tex.z-dn.net/?f=%5BMg%5E%7B2%2B%7D%5D%3D%283%5Ctimes%204.72%5Ctimes%2010%5E%7B-3%7D%29%3D1.416%5Ctimes%2010%5E%7B-2%7DM)
![[PO_4^{3-}]=(2\times 4.72\times 10^{-3})=9.44\times 10^{-3}M](https://tex.z-dn.net/?f=%5BPO_4%5E%7B3-%7D%5D%3D%282%5Ctimes%204.72%5Ctimes%2010%5E%7B-3%7D%29%3D9.44%5Ctimes%2010%5E%7B-3%7DM)
Putting values in above expression, we get:
Hence, the solubility product of magnesium phosphate tribasic is
