A Cu penny can be dissolved in nitric acid however not in hydrochloric acid. Utilizing reduction potentials, show why this is so. Explain what the products are or expected products of each reaction
A student carry out an experiment in which (II) chloride Hexahydrate reacts with ammonia to produce hexamminenickle (II) Chloride (formula = Ni(NH3)6Cl2) as well as water if 6.024 grams of hexamminenicle (II) Chloride are produced, what is the per..
given the following substances, xenon, ammonia, iodine monochloride, and fluorine, and the following statements,
A 25.0 mL sample of a 0.115 M solution of acetic acid is titrated with a 0.144 M solution of NaOH. Calculate the pH of the titration mixture after 10.0, 20.0, and 30.0 mL of base have been added.
Calculate the change in pH when 3.00 mL of 0.100 M HCL(aq) is added to 100.0 mL of a buffer solution that is 0.100 M in NH3 (aq) and 0.100 M in NH4Cl (aq).
Draw the major product for each of the following reactions. Make sure that you draw a major product that could be isolated, not just an intermediate or something that would be present only in low equilibrium population.
Write equations for the folowing seperations. indicate any condition required for the reactions to occur, such as p.H 5. Fe2+ from Cr3+ ions
How might the yield of product be affected by adding twice as much water as is specified, while keeping the quantities of the other reagents the same
