The observation of reaction can be determined from the nature of products formed in the reaction. The products would be written using the solubility rules. 2.) In this given reaction , we can see that CO2 gas is produced in the product. So observation would be : Colorless gas evolved. 3.) In this given reaction , we can see that CO2 gas is produced in the product. So observation would be : Colorless gas evolved. 4) In this given reaction , we can see that HCl gas is produced in the product. So observation would be : Colorless gas evolved. 5.) NaCl (s) + AgNO3 (aq) The solubility rules used here are : 1.) All nitrates are soluble . 2.) The Chloride of Ag+ is insoluble . So, the reaction would be given as : NaCl (s) + AgNO3 (aq) ----> AgCl (s) + NaNO3 (aq) As we can see precipitates of AgCl are formed in this reaction which are white in color. So the observation would be : White precipitate formed. 6) MgSO4 (s) + BaCl2 (aq) The solubility rules used here are : 1.) All chloride of Mg2+ is soluble . 2.) The sulfate of Ba2+ is insoluble . So, the reaction would be given as : MgSO4 (s) + BaCl2 (aq) -----> BaSO4 (s) + MgCl2 (aq) As we can see precipitates of BaSO4 are formed in this reaction which are white in color . So the observation would be : White precipitate formed. 7) The reaction is : Cl2 (aq) + 2 NaI (s) ----> 2 NaCl + I2 (s) In this reaction precipitates of Iodine are formed which are brown in color, so the observation would be : Brown precipitate formed. 8) NaI (s) + AgNO3 (aq) The solubility rules used here are : 1.) All nitrates are soluble . 2.) The iodide of Ag+ is insoluble . So, the reaction would be given as : NaI (s) + AgNO3 (aq) -----> AgI (s) + NaNO3 (aq) As we can see precipitates of AgI are formed in this reaction which are yellow in color, so the observation would be : Yellow precipitate formed.

Hi there, can someone please help me solve for the products of the following reaction? Please make sure to clarify all steps taken to go about solving for the products and explain various terms and rules that should be known or correlate with the question. I'm using these questions to study for our final exam and need some extra clarification on rules and steps. Thank you very much in advance!
You are given the following reactions to complete in lab. However, you recognize an issue with the reaction. 1. Determine why the reactions will not work or why the reactions will give a poor yield? 2. How can you resolve the issues and run the reactions to obtain a better yield? Fix the reactions by redrawing each reaction with the solution (corrected starting materials/reagents/products/etc.).
