And also find the molality of Na+ and S2O32- IONS
PLs explain and solve-Molecular weight of sodium thiosulphate penta-hydrate = 248 ;
1000 ml of3M solution contains 248 X 3 g thiosulphate ;
1 ml of
So what do you guys think is more reliable for identifyig an uknown liquid, its boiling point or molar measurement. I also need reasons as to which one leads to the least errors during calculations.-i
The following is the question:
If 45.5ml of 0.200 M AgNO3 is mixed with 35.8ml of 0.436 M Na2CrO4, what is the theoretical yield of the precipitate silver chromate?
So I thought I was supposed to cal
lower alkanes are slightly soluble in water but as carbon number increase solubility decrease coz non polar property increases.the are more soluble in non polar solvents like ether carbon tetrachlorid
how much heat can be produced if you use 450g of lead in the following reaction:
Pb + 2Cl2 ---> PbCl4ΔH = -330 KJ-Divide 450 g between the molecular weight of the Lead... that will the moles oflead!
Probably just the end of a ponytail, but that would look super cool. Or can you only gold plate metal items?-Yes, but you wouldnt like it.Not the process, nor the expense.It is not possible to gold pl
suppose a solution containing 3.50 g of sodium phosphate is mixed with a solution containing 6.40 g of barium nitrate. how many grams of barium phosphate can be formed?-2Na3PO4+ 3Ba(NO3)2 ------------
Hi there, I am having a bit of trouble understanding the implied meaning of these terms: Overall Redox Equation and Balanced Overall Redox Reaction. Is there any difference between these two terms?
I
Can some one please help me work this out. Many thanks.
The solubility of lead(II) fluoride in water is 0.0175%(w/v) at 29 degrees C. Calculate the Ksp of this salt at this temperature.
a) 1.46 x 10^-
What volume of .035 M sodium hydroxie, in ML, contains 4.24g of solute?
I think the answer is 303 mL but can some one show me how to the steps properly?? its too difficult to grasp..-(4.24 g) / (39.99
above the temperature of 4 degrees Celsius. Is this just some fact were supposed to accept? Im just curious.-Accept???Sure.As long as you accept the basic concepts of density and molecules and the kin
80 mL of water are added to 20 mL of a 1.5 M (concetration) of potassium bromide. What is the final molarity?
I did M1 x V1 = M2 x V2 but the answer I got is 0.375M ...its supposed to be 0.30 M /:-Yo
And or are these nitrates bad for you 10 points for best answer-Nitrates are an impurity that are allowed under 10mg/liter adopted by the usepa as a standard.
higher conc might cause blue baby syndrom
I would really appreciate if you would be able to answer one of these questions.
1. Explain how an electron can be released from the nucleus of an atom.
2. Explain- in general what happens during be
