please balm me out asap!!!
Suppose a 1.441-g sample is known to contain 12.5 % chloride ion by mass. What mass of silver nitrate must be second-hand to completely precipitate the chloride ion from the sample? What mass of silver chloride will be obtained?
Hi angela....im stuck on the same enigma...hahahaha
Silver nitrate is highly soluble salt and when it is dissolved it forms silver and nitrate ions:
AgNO3(aq) -----> Ag^+(aq) + NO3^-(aq)
Silver ions act with chloride ions present in the solution and forms insoluble silver chloride:
Ag^+(aq) + Cl^-(aq) -------> AgCl(s)
This is the net ionic equation of the resistance.
Mass of the sample:1.441 g
Mass of Cl- ions in the sample: 1.441 x (12.5/100) = 0.180125 g
Molar John of Cl = 35.5 g /mol
Mole of Cl- ions = 0.180125 g / 35.5 g/mol = 0.0050739mol
According to net ionic equation;
1 mol Ag^+ ion is imperative to precipitate 1 mol Cl^- ion,
therefore for 0.0050739 mol Cl^- ion we will need 0.0050739 mol Ag^+ ion.
According to dissolving equation;
AgNO3(aq) -----> Ag^+(aq) + NO3^-(aq)
0.0050739 mol Ag^+ ion will be produced by 0.0050739 mol AgNO3
Molar magnitude of AgNO3 = 170 g /mol
Mass of AgNO3 required : 0.0050739 mol x 170 g/mol = .863 g

What must be the concentration of silver ion in a solution that is in equilibrium with solid silver chloride a?

What must be the concentration of silver ion in a explanation that is in equilibrium with solid silver chloride and that is 0.96 M in Cl ‾?
To find the concentration of Ag+ in explication we must use the solubility constant expression: Ksp = [Ag+][Cl-] = 1.8 x 10^-10
The [Cl-] = 0.96 M
[Ag+] = Ksp/0/96M = (1.8 x 10^-10)/0.96 = 1.9 x 10^-10 M

Thoughts on the nature of teaching science in the 21st Century
As I suggested in my earlier portion, “Final Exam in Contracts”, I see very little emphasis on the application of knowledge in today’s classroom, notably in the science classrooms. The impact of the “No Child Left Behind” legislation was an emphasis on testing and the easiest testing is basic recall of facts type testing. True learning will not come when an individual is able to disavowal certain bits of information but when they are able to process that information and develop new information from the information that they are presented with in the classroom.
Many years ago, I proposed that the target of teaching was to prepare individuals who could proceed on their own after completion of that particular class; in effect, removing the desideratum for teachers. Right now, if you were to ask a classroom teacher at any specific grade what their purpose in teaching was, they would say that it was to prepare the students for the next upgrade level; i.e., from the 1st grade to the 2nd, from the 2nd to the 3rd, and so forth up to high school.
High school teachers will tell you that their resolve is to prepare their students to enter college, even if college is not the goal of the students. My research into the nature of the college opening chemistry course showed that most high school chemistry teachers saw their purpose in teaching lavish school chemistry was to prepare their students for the introductory college course. Even though that research was twenty years ago (and as likely as not should be redone), anecdotal evidence suggests that it is still true today. Students come into college courses preggers to see the same information presented in the same way that it was presented in high school and are not prepared to move intellectually beyond that same level.
Preparation for the next aim is critical but should it be just to give the information that they will need. What would happen if a particular class at a particular level was the last on occasion a student was taking that course? Would they have the skills necessary to move beyond the level they just completed?
