I was wondering what dead bacteria look like. I took a 1/4 ounce packet of baking yeast and put it in a cup and mixed in one cup of City of Minneapolis tap...
Have a quantitative precipitation of carbonate ion lab. asking to calculate the number of moles and the mass of calcium carbonate that can be theoretically...
First off, the formula of sodium carbonate is Na2CO3, not NaCO3. To find the moles, one must have the molecular weight/formula weight of Na2CO3. Atomic...
Hey Brian, It makes sense that your chances of seeing a bacteria in stream/river water is pretty slim. They concentration alone is low enough that you'd be...
What are you need exactly to help you? In which analysis are you iterested? mametott <no_reply@yahoogroups.com> wrote: Thank you for the help. I have a lab I...
it is due the reaction's pace and also that it is clearly distinguishable.also the oxidizing agent used is weak and it does not decompose the original...
the formula is Na2CO3 and not NaCO3.the molar mass of sodium carbonate is 106gm/mol. therefore the mass of CaCO3 produced will be 100 from 106 hence 0.28 gms...
You cannot tell just from looking that the aldehyde has been oxidised to a carboxylic acid. Tollen's provides you with a clear way to see if there is a...

You are not showing your work. So I must look up acid dissociation constants in CRC Handbook = 1.77 x 10^-4 So [H+]*[Formate-]/[HFormate]=1.77 x 10^-4 ...
Lauri, The pKa of formic acid is 3.74, so from the HH equation, pH = pKa + log ([formate]/[formic_acid]}, we have pH = 3.74 + log ([formate]/[formic_acid]} So,...

Hi Lifechange! You have to tell us what you mean by "stabilized." Do you mean that gold is soluble in/miscible with/forms a solid solution with mercury?...
Steve, thanks for the reply. I work with aqueous solutions. Yes I've seen the solid solution sometimes when I make up my standards. When making up a stock...
