The total mass of the original tissue were from the source which are the pig ovaries. But first, convert 5.6 tons to mg.
5.6 tons × (1000 kg/1 ton) × (1000 g/1kg)×(1000 mg/1g) = 5.6 x 10^9 mg
Thus, the percentage of estrone in the original tissue is
(12.0 mg /5.6 x 10^-9 mg) x 100 = 2.14 x 10^-7 %
Answer:
0.0300 moles of H₂
Explanation:
The original equation is PV = nRT. We need to change this to show moles (n).
n =
It's important to convert your values to match the constant (r) in terms of units.
30.0 kPa = 0.296 atm
2500 mL = 2.50 L
27 °C = 300 K
Now, plug those values in to solve:
n = - for the sake of keeping the problem clean, I didn't include the units but you should just to make sure everything cancels out :)
Finally, you are left with n = 0.0300 moles of H₂
The answer is (4) solid to gas. The entropy is the measurement of disorder. The entropy of CO2 under different status will increase from solid to liquid to gas. So the answer is (4).
Answer:
50 C?
Explanation:
90 - 40 = 50 So 50 degrees celsius is your answer
Answer:
During the uncoupling of electron transport chain energy that is generated by the transport of electron along with proton, is released as heat.
Explanation:
The proton motive force generate energy for the phosphorylation of ADP with inorganic phosphate to form ATP an energy rich molecule during the process called oxidative phosphorylation.
There are some chemical agents knowns as uncouplers for examole thermogennin,2'4-dinitophenyl.They does not interfere with the transport of electrons through various electron carriers which generate energy,but uncouplers blocks the phosphorylation step.
As a result the energy that is released during transport of electron, is liberated as heat.
