I think I might be on the right track, if someone could let me know if this is correct I would greatly appreciate it. A 51 kg diver is spinning forward in a tuck position at 1.9 rev/s, as shown in Fig. 13-38a. In this position, the diver's rotational inertia is 3.3 kg&midd...

you know the pH of HNO3 to be 3.4 use pH=-log [] 10^-3.4= ?
biochemistry
the equation will look like this: pH=7.20+log 0.4/0.2 = 7.50 Yes?
biochemistry
Sorry the final pH of the mixture is 7.50, is that correct DrBob222?
biochemistry
pH=7.20+log 0.2M/ 0.4M pH=7.20+(-0.30) pH=6.69 I'm heading in the right direction?
biochemistry
pH=7.20+log0.1M/0.1M pH=7.20
biochemistry
pH= pKa + log 0.1M/0.1M what's the pKa value?
biochemistry
what's the pKa?

if 4 volumes of 0.1M monobasic potassium phosphate, KH2PO4, are mixed with 2 volume of 0.1 M dibasic sodium phosphate, Na2HPO4, what will be the pH of the mixture? What if 4 volumes of 0.1 M KH2PO4 are mixed with 8 volumes of 0.1 M ethanolamine base(pka=9.44) what will be pH o...

CO (g) + Cl2 (g) ↔ COCl2 (g In one experiment, 0.93 bar of CO was combined with 1.01 bars of Cl¬2 in a reaction vessel at 700K. After the system reached equilibrium, the total pressure was 1.24 bars. Calculate Kp0 for the system.
