Does anyone know what steps they are following to get a final answer of 1 x 10-6 for s0 ?

Any help appreciated

Thanks

Here's what I did but I'm not sure if I'm right: So for n=3 (Nickel), there are 16 electrons in the ground state (yes?). and then to find the magnetic quantum number, I must first find l (which is n-1). So since n in this case is 3, I subtracted 1 to get an l of 2. so the magnetic quantum number can be from -2 to +2 (-2,-1,0,1,2).

So i am stuck here, I do not fully understand what the question is asking, though I do understand how to basically find the quantum numbers. Any help? ]]>

im on the look for a Barium Titanate crystal, about eight inches long, double terminated – in other words, a point on each side, sort of an octagon shape. :-)

Anyone know where i can get that? ]]>

Initial p(A) - 10.0 atm

Initial p(B) - 10.0 atm

Initial p(C) - 0.0 atm

What I have so far:

Since total pressure remains the same the amount of pressure taken away from A and B must be same as the increase in C so:

A + B ==> 2C

Other than this I have no clue on how to get a value for equilibrium pressure, HELP! ]]>

I am new here. I have one problem that I would greatly appreciate your help.I have data of citric acid (dominant acid) and two other acids (malic and glutamic)of a certain garden fruit measured by spectrophometric method and they are given in

However for some analytical purposes I would also want the percentage titratable acidity given as

thanks !

I am confused on what formulas to use when answering questions like these:

1. A sample of pond water contained 88.00 µg g−1 of dissolved oxygen gas. Calculate the amount in grams of dissolved oxygen in 4.00 L of pond water.

2. A desirable level of dissolved oxygen in river water is 8 ppm. A sample of river water is found to have less than this, with 5.60 ppm oxygen. If 1.40 µg of dissolved oxygen was actually present in the sample, calculate the mass of water tested.

If someone could help me or give me some steps to solve the problems that would be great. Please explain simply :) ]]>

Im new to this forum and i will be greatful if someone could help me with my questions.

I dont know much about chemistry but my mission is to mix a liquid fuel that burns with a red flame and it cant be too toxic or highly flammable.

So i have to mix a fuel that burns with a non yellow flame with a salt of lithium that is soluble in that fuel.

Maybe i can use one of this as fuel/solvent?

* Propylene glycol

* Tripropylene glycol

* Ethylene glycol (too toxic, can not use)

* Triethylene glycol

* Glycerol

Other?

Maybe i can use one of this as a solute?

* Lithium Nitrate

* Lithium Acetylacetonate

* Lithium Sulfide

* Lithium Iodide

* Lithium Acetate

* Lithium Sulfate / monohydrate

* Lithium Perchlorate

* Lithium Bromide

* Lithium Chloride (can not use, fouling of wick)

I have tried solutions of propylene glycol with lithium chloride but the light went out because the wick got dirty very quickly.

Also tried propylene glycol with lithium bromide but i think it was not very soluble?

Grateful for any help.

Thank you. ]]>

Is there anything else that you guys can think of that would make these lamps go bad?

Thank you :) ]]>

and also balance this equation .....

Can anyone please help me to convert brine flow l/h to kg/h? I just want to compare last year Brine consumption but WTW plant has it in l/h while procurement send me the info in tonne/year.

Thanks in advance for your help. ]]>
