Equation for Part A above
1. Write net-ionic equations for the following precipitation reactions: a) The reaction between barium nitrate and sulfuric acid. b) The reaction between calcium nitrate and sodium oxalate. 2. Elements A, B, and C exist as the diatomic molecules A2, B2, and C2. All act as oxidizing agents, i.e., they take electrons from other species. In aqueous solution, A2 is green, B2 is yellow, and C2 is red. When they have gained electrons from other species,...

Name All of the common noble gases are monatomic and low-boiling. Their boiling points in℃are: Ne--245; Ar--186. Kr--152, Xe--107. Using the periodic table, what can you conclude about the boiling point of Rn from these data? 1. 2. Substances A, B, and C can all act as oxidizing agents. In solution, A is green, B is yellow, and C is red. In the reactions in which they participate, they are reduced to A B and C-ions, all of which are...

Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...

Hi,
can anyone please help me with this? i have no clue how to define
if a reaction is Oxidation reduction or not. Thanks a lot
OXIDATION-REDUCTION Introduction Chemists refer to reactions which involve a transfer of electrons from one reactant to another as oxidation reduction reactions of just "redox" reactions. Oxidation is defined as a loss of electron and reduction as a gain of electron by a substance during a chemical reaction. The loss of electrons by one substance...
