In this experiment we assume the single nonbonding electron on the N atom in the NO2 molecule occupies a hybridization ORBITAL resulting in a bent molecule if we assume this electron remains in the unhybridized atomic orbital what is the prediction shape of the NO2 molecule? Which structure correctly predicts in N02 to be a polar a molecule
determine the melting point of an aqueous solution containing 147mg of saccharin c7h5o3ns added to 1.00ml of water
If I burn 0.315 moles of hexane (C6H14) in a bomb calorimeter containing 5.65 liters of water, what's the molar heat of combustion of hexane is the water temperature rises 55.4 ºC? The heat capacity of water is 4.184 J/g ºC .
Draw the structure of the alkoxide and the alkyl bromide needed to produce 2-ethoxy-2-methylpropane
Carbon oxide (carbon (II) oxide) can be purified of oxygen impurities by having it react with cobalt (II) oxide. If the impure carbon oxide contains a volume of 1.5% oxygen, and if it reacts with cobalt (II) oxide at 250 °C and 500 kPa.
The best design for rockets is one in which both fuel materials run out at the same time to minimize excess mass. If the total mass of both components in a decaborane/oxygen rocket must be 3.011E+6g, what mass of liquid oxygen should be used
Calculate the molarity of S2O32- if 3.0 mL 0.10 M K2S2O8, 2.0 mL 0.10 M K2SO4, 1.0 mL 2% starch, 2.0 mL 0.010 M Na2S2O3, and 5.0 mL 0.20 M KI are mixed.
Explain how Le Chatelier's Principle affects the extent of the dissociation of acetic acid in a buffer that is 0.10 M acetic acid and 0.10 M acetate ion
Calculate the total concentration of lead dissolved ([Pb]total) in a solution saturated with PbI2(s) and containing dissolved I- with a concentration of [I-] = 0.294 M. The solubility of lead is governed by the reactions shown below.
A Raman spectrum is measured with a 630nm Laser. Stokes lines are collected. The Raman spectrum has a peak at 1700cm-1 what is the wavelength of this peak. Planck's constant = 6.626x10-34 Js
Predict that it was dissolved in HCl then mixed into the diethyl ether because diethyl ether is a base and since the benzoate contains an amine group they would remain unreactive with one another.
Mt. Kilimanjaro in Tanzania is the tallest peak in Africa (19,340 ft.). On a particular day, the barometric pressure at the top of the mountain was 330 torr. On that day, at what Celsius temperature did water boil on the top of the mountain?
A ground-state H atom absorbs a photon of wavelength 94.91 nm, and its electron attains a higher energy level. The atom then emits two photons: one of wavelength 1281 nm to reach an intermediate level, and a second to return to the ground state.
