Write balanced net ionic equations for the following reactions in acid solution. 

Given the following descriptions of reversible reactions, write a balanced net ionic equation (simplest whole-number coefficients) and die equilibrium constant expression (X) for each. 

Write balanced net ionic equations to explain why a precipitate dissolves in... 

A solution of potassium dichromate is made basic with sodium hydroxide the color changes from red to yellow. Addition of silver nitrate to the yellow solution gives a precipitate. This precipitate dissolves in concentrated ammonia but re-forms when nitric acid is added. Write balanced net ionic equations for all the reactions in this sequence.

K.23 A mixture of 5.00 g of Cr(N03)2 and 6.00 g of C11SO4 is dissolved in sufficient water to make 250.0 mL of solution, where the cations react. In the reaction, copper metal is formed and each chromium ion loses one electron, (a) Write the net ionic equation, (b) What is the number of electrons transferred in the balanced equation written with the smallest whole-... 

Elements and charge are both balanced so this is the fully balanced net ionic equation. 

Ammonium nitrate, a colorless Ionic solid used as a fertilizer, explodes when it is heated above 300 °C. The products are three gases molecular nitrogen, molecular oxygen, and steam (water vapor). Write a balanced equation for the explosion of ammonium nitrate. 

Species present K, Fe, Cl, OH, H2 O other experments show that KCl is a soluble salt, so the only possible precipitate contains Fe cations and OH" anions. We describe this precipitation by a balanced net ionic equation that contains only those species involved in the reaction. The substance that forms contains three OH anions combined with every Fe cation, resulting in a neutral product. Thus, the reactant species are Fe " " cations and OH anions with stoichiometric coefficients of 1 and 3. Here is the net ionic equation ... 

Each side of this balanced equation has a net charge of +2. Remember, however, that the net ionic equation does not show all of the species present in solution, in this example. Cl ions balance out the positive charges of ond H3 O. All solutions...
