Answer:
3.50*10^-11 mol3 dm-9
Explanation:
A silver rod and a SHE are dipped into a saturated aqueous solution of silver oxalate, Ag2C2O4, at 25°C. The measured potential difference between the rod and the SHE is 0.5812 V, the rod being positive. Calculate the solubility product constant for silver oxalate.
Ag2C2O4 --> 2Ag+ + C2O4 2-
So Ksp = [Ag+]^2 * [C2O42-]
In 1 L, 2.06*10^-4 mol of silver oxalate dissolve, giving, the same number of mol of oxalate ions, and twice the number of mol (4.12*10^-4) of silver ions.
So Ksp = (4.12*10^-4)^2 * (2.06*10^-4)
= 3.50*10^-11 mol3 dm-9
<span>These elements are red. They are typically gaseous at normal temperatures: some examples can include oxygen, hydrogen, and the noble gases (neon, argon, krypton). These elements all use the concept of STP (standard temperature and pressure) as their baseline: 1 atmosphere of pressure and 0 degrees Celsius.</span>
Answer:
A
Explanation:
B is incorrect because asexual reproduction produces an offspring exactly the same as it's parent. Thus the probability does not need to be calculated.
C and D logically do not make sense since B is incorrect and A is correct. I provided the explanation why it is incorrect above.
Thus A is the correct answer.

When a liquid absorbs heat energy without increasing its temperature is because it is using the absorbed heat for the change of phase from liquid to vapor. This is call vaporization. Vaporization requires energy because the molecules have to overcome the interaction that keeps them close to their neighbors in the liquid.So, <span>the answer is the option B.) it vaporizes.</span>
