what is the total pressure exerted by a mixture of 2.50g H2 and 4.00g N2 in a sealed 4L vessel at 25 C?-2.50g H2 x1 mol H2/2 g H2 = 1.25 mol H2
4 g N2 x 1 mol N2/ 28 g N2 = 0.14 N2 mol - Limiting reac
please show me how you would solve this problem!

Which of the following distinguishing electrons represents an element with properties similar to an element with a 3p^3 distinguishing electron?
4p^3 3p^2 3d^3 2p^2-4p^3-4p3
For nernst equation, if the reactant is given in partial pressure form. do we need to change it to concentration to calculate Q?-Yes, I think so.You could use PV=nRT to obtain n, molar concentration t
Changing concentrations
The facts
Equilibrium constants arent changed if you change the concentrations of things present in the equilibrium. The only thing that changes an equilibrium constant is a
43 protons, 43 electrons 43 protons, 56 electrons 56 protons, 43 electrons 99 protons, 43 electrons-Technicium has an atomic number of 43, meaning that it has 43 protons, and a neutral atom will have
If my slope is .1343, the y-int is -.0427, and the r2 value is .9772, the absorbance is .376 how would i get the phosphate concentration?
I have already gotten this problem wrong and the answer is su
4, 5 or 6. Depending on the strength of the dilution.
pH7 is neutral and 1,2 and 3 are full acid
Hope this helps:)-Which acid?
What is the concentration?
These have to be known before the pH can b
it is a galvanic cell,
Zn(s) + Cu 2+ (aq)-> Cu (s) + Zn 2+ (aq)-it would be log [Zn++]/[Cu++] in eqn
Ecell = +1.10 - 0.0592/2 log(0.020/0.200)
Ecell = +1.10 - 0.0592/2 log(10^-1)
Ecell = +1.10 +

Can someone give me a detailed explanation, I really dont understand.
I thought Lead has four valence electrons... so why does the charge of 2+ come in?
Im sorry I really dont get in.-Lead has differ
