9. Given that the Ksp for calcium fluoride [CaF2] is 3.2 x 10^-15, which of the following describes a solution that is 2.00 x 10^-5 M NaF and 2.00 x 10^5 M Ca(NO3)2? A) Q = 4 x 10^-10 and there will be a precipitate formed B) Q = 8 x 10^-10 and there will be a precipitate formed C) Q = 8 x 10^-15...
1. a) Write the precipitation reaction for sodium hydroxide and silver nitrate. Label the precipitate. b) Write the precipitation reaction for iron (III) nitrate and sodium phosphate. Label the precipitate. c) Write the neutralization reaction for HBr and Ba(OH)2 Please show the right work and explanation to answers for a b c problems.
4. Uranium Mine Extraction (10 points) The owner of a uranium mine hires you as an economist and asks you to determine the optimal number of uranium ore which should be extracted from the mine this year (q0) and next year (q1), after which time no mining will be possible. The owner would therefore like to extract all the uranium ore by the end of the second year. There are 60 tons of uranium ore in the ground. The price...
Please solve. I will upvote.
(, A nuclear reactor uses uranium 235 to produce energy. What is the order of magnitude of the energy equivalent of 6 x 10-4 kg of uranium 235? (A) 105 J (B) 108 J (C) 1014 J (D) 1017 J (E) 1020 J Each of the following nuclei has been stripped of " all electrons and placed the same distance from an alpha particle. Which nucleus exerts the strongest electrostatic force on the alpha particle?...
MgF2(s) <--> Mg2+(aq) + 2 Fâ(aq) In a saturated solution of MgF2 at 18 0C, the concentration of Mg2+ is 1.21 x 10â3 molar. The equilibrium is represented by the equation above. (a) Write the expression for the solubility-product constant, Ksp, and calculate its value at 18 0C. (b) Calculate the equilibrium concentration of Mg2+ in 1.000 liter of saturated MgF2 solution at 18 0C to which 0.100 mole of solid KF has been added. The KF dissolves completely. Assume...

IMPORTANT: I don't need help with "a". However, I do need help
with b&c
IMPORTANT: I understand that there's a walkthrough given bellow.
However, I do not understand the walkthrough given for b&c.
Part B
- Why does E(x)+E(y)=2u (2 mew)?
-What is this?: I honestly have no idea what it
is. Please explain to me what it is and what its significance is
within the problem.
-This may be the same thing as the symbol above, but just in...
1) ~A + (~(A+B))* C + B a.) ~A + ~A + ~ B * C + B b.) ~B c.) ~A + B d.) ~A (~B + C) +B e.) ~A please answer the question with detailed steps and explanation on which boolean identities were used. I know the answer, but don't know how to get it. show all work
IMPORTANT: I realize that the answer/walkthrough is posted. What
I need help with is the point where the derivative of (K/L) is
being taken with respect to MRTS. At that point on I'm totally lost
in what's going on. Please give a very detailed explanation of how
the derivative of (K/L) is taken with respect to MRTS. I have no
idea where the -1/p came from or where the p+1 exponent came from.
Please show me in a detailed way...
Could someone plz help me with this 4 questions
