andie

yes i do have a diagram for it, but now I need to know how to attempt solving the problem.

I need help answering this question:

A chage +q is located at the origin, while an identical charge is located on the x-axis at x= +0.50m. A third charge of +2q is located on the x-axis at such a place that the net electrostatic force on the charge at the origin doubles, its direction remaining unchanged. Where should the third charge be located?

I need some pointers on how to answer the question.

PLEASE HELP!

Hey!

I need some help balancing the equation:

C2O4 2-(aq) + MnO4 -(aq) --> Co2 (g) + MnO2(s) in a basic solution. I am not getting it right so i need some help determining it. I can do the reduction half- reaction , but not the oxidation half-reaction.

PLEASE HELP!

excellent thank you!

Okay i understand what you are saying. So then then solution contains the Ag+, and Fe3+. Right?

Hey!

I have to answer this question about and unknown solution: The unknown solution could be Ag+, Ba2+, or Fe 3+.To find which cations are in the solution you add the following solutions. No precipitate is formed when NaCl or Na2So4 is added to the solution. When NaOH is added a precipitate forms. Which cations are present of the 3 mentioned above?

I answered the question that the cations present are Ag+, and Fe3+ because they are more insoluble thatn Ba2+ which produces Ba(OH)2 (aq).

Am I right with the explanation or totally wrong?

PLEASE HELP!!!!!

Thank you!

I am doing a first year chemistry pre-lab and I was wondering what the net ionic equation would be for : adding solid silver nitrate to aqueous hydrochloric acid. I know it produces solid silver chloride and aqueous nitric acid.

Please Help!!!!
