1.0000 grams of an unknown alloy is dissolved and diluted to 1 liter. Oxygen is bubbled through the solution
to oxidize each of the metals to their highest oxidation state. The sample is known to contain only Fe, Al, Ni,
Co, and Cu. 100.00 mL aliquots are taken for each of the following...
[SOLVED] Mircoscale techniques
how could it be possible to filter a reaction mixture and wash/recover the product without exposing it to air using microscale techniques, but without using a glove bag or glove box
Homework Statement
A solution is to be buffer at pH = 3:35 with formic acid and formate.
(a) How many moles of formic acid and sodium formate are needed if the solution is to change pH by < 0:02
for the addition of 0.02 moles of strong acid?
i need help how to set up a problem like...

Show that the Joule-Thompson experiment is an isenthalpic process. (ΔH=0). The experimentally determined quantity is (Partial derivative T)/(Partial derivative P)H . Starting with the total differential for H, show that:
(Partial deriv H)/(Partial deriv P)T = -...
so would be something like this if iam understanding right
and this is what i got when i sloved it
P=(.007308Kg of CO2)(450m/s)*2
P= 6.57738
so then
F= 6.57738/1sec
F= 6.57738
and fianlly
P= 6.57738/.0001m^2
i converted the area of 1.00cm^2 to .0001m^2 and used this as area...
well since its a gas it would bounce of the wall and this is the question again
"If 1.0 x 10^23 carbon dioxide molecules strike 1.0 cm2 of wall per second at a 90o angle to the wall when moving toward it with a speed of 45,000 cm/s, what pressure (in atm) do they exert on the wall?"
and...
Calc 1, 2 or 3 ?
Calc one is pretty streight forward since all you do is take derivatives like
f(x)= 2x^2 + 3x - 8
f'(x)= 4x + 3
but its not all like this, this is just a very simple example, like the power rule, chain rule, product rule, qoutient rule are all calc 1 and more but as far...
ok well i can't use F=ma since the problem has a velocity and not acceleration, but momentum can be used in this way, i hope iam right :)
so F = P/t
So for P =(CO2 in Kg * 450m/s) then F= (CO2Kg*450m/s)/(1sec) then when i get Force put it bake into P=F/A
so then
P=...
well if infinity is not a number but a concept how do you explain where numbers don't end
like if you draw a circle and start to draw lines from the center accros, and so on until you can't draw them anymore, but you can take a sharper pencil and draw even more lines, there will always be a...
