ph
amt of (nh4)2so4 to be added to 500 ml 0.1M nh4oh to prepare a buffer of ph 9.56. pka of nh4+ is 9.26
where am i going wrong...
WPE+ Circular
in this question Tmax = 5 Tmin
so Tmin = mg/5
at highest position T is giving centripetal acc
mg/5 = mv2/r
v2 = gr/5 = 2...
ionic
in which of the following case(s) solubility of ch3cooag would be less than that in pure water at 25 deg celsius
WPE, Potential Energy , EQM
sir said when putting -du/dr = 0 we get condition for eqm , can anyone tell why?
Basic com doubt
how is momentum conservation applied as there is a constant force(gravity) acting on the two particles>?
chemistry -i order doubt
@iTeachChem can you please help me combine these both the order
The 1st one I found on internet
And the second is what is in my notes...
Combination of Resistors
why is C option wrong
There will be n-1 sides left with all of them in series , eq resistance = (n-1)R
one R will be in parallel (btw corners)
...
Equivalent resistance
I don't understand how the circuit will be simplified here. Please give a solution for this.
