bobpursley plz check
i m getting 9.77 g for Bi2S3 . no limiting reactant .. both are same .. can u plz conform
Can you repost #1 please. Thanks.
1) How many drops of 12M HCl would you add to 1.00 L of 0.100 M HC2H3O2 to make [C2H3O2-] = 1.0 x 10^-4 M? Assume that 1 drop = 0.050 mL and that the volume of the solution remains 1.00 L after the 12 M HCl is diluted. [Hint: What must be the [H3O+] in the solution?] 2. What m...
I'm sorry I made a typo it goes through a solution of Al(NO3)3 and that's why I mutliplied the m.w. of Al by 3 because you have 3 moles of Al per NO3
What mass of Al can be deposited by the passage of a constant current of 5.00 A through a Al(NO3)2 solution of 2.00 hours? My work: Q= I*t = 5 * 7200sec = 36000 36000/96458= .3732 .3732* 1/3 * (26.98*3) = 10.06g But this is wrong it's suppose to be 3.3.6g. why is that?
thanx alot =)
Consider a system consisting of a cylinder with a movable piston containing 10^6 gas molecules at 298K at a volume of 1L. Consider the following descriptions of this system: 1. Initial system 2. Starting from the initial system, the volume of the container is changed to 2L and...
thanx a tons =)
ok thanks alot... the PartB asks for: What is the percent ionization of ammonia at this concentration?
sorry the 2nd question is the right one
