For each of the following molecules, offer a Lewis structure, including resonance as well as formal charge. Forecast the electron-domain geometry, the molecular geometry as well as the hybridization of the central atom. For each nonionic species define whether it will be polar or non-polar.
a) SeO2 b) XeF4 c) PCl5 d) BrF2- determines methyl cyanide, H3CCN.
a) Depict the best possible Lewis structure of methyl cyanide. b) Forecast the geometry and hybridization of each carbon atom. c) Explain the bonding in this molecule in terms of sigma (s) and/or pi (p) bonds and the orbitals
An oligomeric protein has a molecular weight of 168000. A 420 mg sample was treated with an excess of 1-fluoro-2,4-dinitrobenzene (Sanger\'s reagent) until the reaction was complete
A solid mixture consists of 51.0 g ofKNO3 (potassium nitrate) and 9.0 gofK2SO4 (potassium sulfate). The mixture is added to 130g of water. If the solution described in the introduction is cooled to 0 degrees celsius
A cylindrical gas chamber has a piston at one end that can be used to compress or expand the gas. If the gas is initially at 928.1 Torr and when the volume is 7.351 L, what will the pressure be in mmHg if the volume is adjusted to 3.570 L
Determine the reaction when aqueous solutions of aluminum acetate and copper(II) bromide are combined. The net ionic equation for this reaction is
Carbon-dating evaluates the ratio of radioactive carbon-14 to stable carbon-12. Given the amount of carbon-12 contained a measured sample cut from the document, there would have been about 1.3 × 10-12 grams of carbon-14 in the sample when the parc..
The gas remaining in the first container shows a pressure of 1.710 atm. Calculate the volume of the spherical container.
The freezing point of pure benzene is 5.5 Celsius and its freezing point constant is 5.12 C/m. Calculate the molecular weight of the unknown.
A tank of oxygen holds 20.0 L of oxygen (O2) at a pressure of 15.0 atm. When the gas is released, it provides 300. L of oxygen. What is the pressure of this same gas at a volume of 300. L and constant temperature
