Explain as thoroughly as possible, because I seriously don't get ionizing very much When copper and silver nitrate oxidize/reduce, how does copper lose 2 electrons? Why not just one? Or three for that matter? Cu (s) + 2 Ag+ (aq) --> Cu^2+ (aq) +2 Ag (s)
This is for two dimensional arrays with both positive and negations ions alternating in a square pattern. I am given the hint to select an area with boundries through the middle of the outermost ions-ie the edge ions count as 1/2
When a 18.5 g piece of copper originally at 99.5C is placed in 58.5 g of water at 24.0C, the temperature of the water rises to 26.1C. If the specific heat of water is 4.180 J , calculate the specific heat of copper. can you show work and the anser..
A .483 mol sample of graphite was heated with 2.14 mol oxygen gas to form carbon dioxide. Graphite is the limiting reagent in this reaction. Calculate the total moles of gas present after the reaction?
Compute the volume of the tank if the total pressure of the mixture is 44.08 psi at 86°F. What is the partial pressure of each constituent and the average molecular weight of the mixture
Sodium bicarbonate decomposes to form the final solid product sodium oxide. Using a balanced equation, you are to convert the grams of sodium bicarbonate, one number is 5.213, to moles.
a) What is the structure of biacetyl? b) Indicate the hybridization of each carbon atom. c) How many pi bonds are present? d) Do the four carbon atoms lie in a plane or do they lie in a straight line?
Chloropropionic acid, ClCH2CH2COOH is a weak monoprotic acid with Ka = 7.94 x 10-5 M. Calculate the pH at the equivalence point in a titration 38.2 mL of 1.05 M chloropropionic acid with 0.90 M KOH
Identify the likely kinds of intermolecular forces in the following substances: HCL , CH3CH3, CH3NH2, Kr
What gas escaped during the sodium bicarbonate washing? Write balanced equations for two reactions that took place during this operation. Experiment: Preparation of synthetic banana oil
how do you know weather it undergoes the E1 mechanism or the E2 mechanism?
A sample of a gas in a piston/cyclinder apparatus occupies 33.1 mL at 1.14 atm and 23.3°C. If the volume of the sample is increased to 77.4 mL and the temperature changes to 39.9°C, what is the new pressure, in atm, of the sample
