Can someone explain why these answers are correct? I don't understand this. Thanks. 4) What is the effective pH range of buffers formed with the following acids? a) Hydrofluoric acid pka = 3.17 effective buffer range 2.17 to 4.17 b) Acetic acid pKa = 4.74 effective buffer range 3.74 to 5.74 c) Ammonia pKb = 4.75 pKa = 9.25 effective buffer range 8.25 to 10.25
I'm confused and don't understand this very well. Can someone please explain why we do the computations to arrive at these numbers? I know that this is easy math, I just don't understand it conceptually. Therefore, I don't know when to do what computations and why. Thanks Show computations & answers. # of dividend shares = (5), *.2) # of dividend shares = computation: 150,00 X.1) ) answer: 5, $ 10% stock dividend value (FMV = $25/share) (D, 20% stock...

Can someone please explain the last point as I don't quite understand? Thanks! li m2[T2 – T3] – m1[T3 – T1] = 0 Q2 01 Experiment 1 Watch the experiment 1 video and extract measurements of T1, T2,T3 and m = mı + m2. Find the mass of each quantity of water without using CAL = 4184J/kg°C. value Please show your working below m = 0.1540 kg m2 (55.6 – 18] – m1 [18 – 3.4] = 0 m2 =...

I don't quite understand how to answer this question can someone please explain it? You perform a conjugation experiment using Hfr lys+his+gly + amp with F-lys-his-gly -amp and you observe the following Minimal Medium with lysine and glycine ampicillin 40 CFU Minimal Medium with histidine and glycine ampicillin 410 CEU Minimal Medium with lysine and histidine ampicillin 150 CFU 14) not let buti la n What is the order of gene transfer? lysine, glycine, histidine What is the purpose of...
Can someone explain Carbonate for me? CO3 what I don't understand: visualizing the loss of electrons, when I see other ionic compounds like PO4 I just count backwards along the periodic table to account for the charges of the oxygen atoms, yet when I attempt to do that with C, you end up in the grey area of the periodic table where no element exists (the d block next to the He atom). Furthermore since Carbon loses all of its...
2x^2+10x+12=0 Can someone please explain this to me with steps. I don't understand it quite yet, steps and an explanation would be very helpful. I'm very, very new to this. Factor
