"These structures are sometimes described as "cellular power plants" because they generate most of the cell's supply of adenosine triphosphate (ATP), used as a source of chemical energy.[2] In addition to supplying cellular energy, mitochondria are
okay so then Q = [5.69x10^-9]^2/1.3405 = 3.238x10^-9/1.3405 = 2.42x10^-9 ΔG = 42.20 + (.00833145)(298) ln (2.42x10^-9) = 42.40 + (2.477) (-19.84) = 42.40 + -49.144 = -6.74 rounded to 7 which is correct. Thank you sir!
I agree with Carls. France didn't become an ally until much later in the war.
It's definitely not A or B. Ionic compounds share electrons, I keep thinking of NaCl and KBr which are both ionic compounds. I've drawn both in lewis dot structures multiple times, so A is out, as well as B. C is out because ionic compounds share
I usually convert it (especially in ΔG = ΔGº + RTlnQ ) because it will confuse me other wise and I will get wrong numbers. I usually keep kJ because that's usually what I need, unless specified otherwise. I suppose I don't need to convert it for ΔG =
Looking at laws of log: log(a+b) 3- log x + log 2 = 5 3- log x + .30103 = 5 Combining like terms, and moving log to the other side so we can stay positive 3- log x + .30103 = 5 + log x -5 3+.30103-5 = log x you can continue doing this and isolate x by
grapefruit juice is considered acidic. So the question becomes what part of the pH scale is acidic?
Usually informants have a agreement with the government so that they have a lesser sentence or freedom while their gang mates get caught
Did you try doing the Stoichiometric equation? Mg - 24.31 g Cl - 35.45 g Total Mass - 59.76 g 29g MgCl (1 mol MgCl/59.76g)= the answer.

I'm using .0083145 for R because the -10.31 is in kJ
I'll even try the inverse -2.478/-10.33 =lnK .2399 = lnK e^(.2399)= 1.27 = incorrect
I think I tried that. Let me show u my notes: -10.30 kJ = -(.0083145)(298) lnK -10.30 kJ = -2.478 lnK -10.30/-2.478 = lnK 4.157 = lnK e^(4.157) = 63.88 = Incorrect.
Nope. That gives me .0156621, and when I input that I got the response "Incorrect. The standard free energy change is negative." I changed it to a negative and it still didn't work.
