Ok, so let me make sure I'm getting these right... -Fe(+3) + 3OH(-) --> Cr(OH)3 -Cr(+3) + 3OH(-) --> Fe(OH)3 -Cu(+3) + 2NH3 --> Cu(NH3)2(+3) -Ag(+) + 6NH3 --> Ag(NH3)6(+) am I on the right track with those?

Homework Statement I need to find net ionic equations for: -Fe(NO3)3 + NH3 -Cr(NO3)3 + NH3 -Cu(NO3)2 + NH3 -AgNO3 + NH3 -Cr(OH)3 + NaOH -Fe(OH)3 +NaOH and a whole bunch of other reactions. I have no problem with writing the balanced equations but I get a little stuck on breaking things...

Ok, lab work... I have to figure out a way to separate out the individual cations from a solution containing Fe(NO3)2, Cr(NO3)2, Ag(NO3), and Ni(NO3)2 and get each one into a particular form and perform a confirmatory test on it. I've think I know how to get started on it. First adding some...

My diagram shows puck A moving in the positive x direction at 40 m/s and colliding with puck B. After the collision puck A is deflected 30.0 degrees relative to the positive x-axis at some final velocity. Puck B moves from rest to some final velocity 45 degrees relative to the negative x axis...

Homework Statement A hockey puck B rests on a smooth surface of ice and is struck by a second puck A , which was originally traveling at 40.0 m/s and which is deflected 30.0 degrees from its original direction. Puck B acquires a velocity at a 45.0 degree angle to the original direction of A...

Homework Statement Ok, this is a lab related question. Given a diluted solution of approximately 1.25M H2SO4, determine the amount of solution needed to use for titration with the base you prepared and standardized. Do not use a volume of battery acid that will require more than 20mL of base...

I tried that and only ended up confusing myself more, I can usually figure out displacement vectors for something that's one direction, then another, but this whole circle thing is throwing me off

Homework Statement A runner jogs around a circular track 160 ft in diameter, what is the magnitude of the displacement vector when the runner has completed 1/4 of a lap? 1/2 a lap? What is the direction of the runner's displacement vector at 1/4 and 1/2 a lap? What is the magnitude of the...
