Title: Write equations for Bronsted/Lowry Acid-Base reactions
Post by: parth252 on January 18, 2009, 08:45:35 PM

Write the correct equations for the principal Bronsted/Lowry Acid/Base reactions occurring at normal laboratory condition for each of the following.

A). 4 mL of 0.5 M HF is mixed with 2 mL of 0.4 M K2CO3. (One Equation)
B). 459 mL of 0.22 M NH4 HSO4 is treated with 0.20 mols of Na2S (s). (Three Equations)

Go ahead and write the balanced equation for 1.

can anyone give me the chemical equation for:
FeCl3+KSCN=?

NaCl+NH4NO3=?

Na2CO3+HNO3=?

Pb(NO3)2+Na2CO3=?

CuSO4+NH3=?

Well, you worked it out for yourself in your other thread, over here:

Na2HPO4 + HNO3------>   NaNO3 aq + H3PO4 aq(colourless solution)
                                   
  Na2SO4 + HNO3   ------->NaNO3 aq  +  H2SO4 aq(colouless solution)

So can you apply some of that knowledge to a few of these examples of yours?

Everyone is new, to everything, at some point.  You are also new to these forums, so I have to tell you something important -- forum rules specify that you have to show some effort.  We can't just give you answers. 

First off, it's cheating, and your school could very well track us down, and at least complain to Mitch, if not do even worse to him, and end up shutting down the board. 

Second of all, it's better for you, if you learn yourself, so you'll be ready for anything, when exam time comes and, almost important, in your real life chemistry career, when the problems come up again. 

Besides which, answering the same, very simple question, over and over again, is dull for us.  We really don't want to field questions form everyone in your class, "I mixed these, now what.  And these, now what.  And this.  And this.  Oh, and this."  It's just tiring, and in the end, doesn't make this board a better place for others to learn.

Here's something we can all do, click on you name, and see all your posts (even when you post randomly in a different thread, which also isn't very helpful):  http://www.chemicalforums.com/index.php?action=profile;u=24714;sa=showPosts
Print them out, and see, what is your real question, what do you know, and what do you not know.  And how can you pull the knowledge together, to learn what you need to know.
