Some water dissolves in liquid methane at -161 degrees C, the boiling point of liquid methane, to give a solution in which the mole fraction of water is 6*10^-5. Determine the mass of water (in units of grams) dissolved in 115L of this solution if the density of the solution is 0.78g/mL. Explain thoroughly please.
Calculate the final pressure of a gas if a 953-mL sample of the gas at 1.25 atm and 50.0 degrees Celsius is changed to 1.55 L at 75.0 degrees Celsius.Be sure to include units and correct significant figures
determine the initial concentration - Constant rate is 3.20×10-4 M/s for a zero-order reaction. concentration has dropped to 9.00×10-2 M after 60.0 seconds
the growth rate drops 6 orders of magnitude and effectively reduces the crystallization rate to zero. Calculate the self-diffusion of this alloy system.
liquid nitrogen has a density of 0.807 g/ml at -195.8 C, if 1.00 L of N2 is allowed to warm to 25 C at a pressure
Mark the True statement A. In carbon containing compounds, carbon usually forms four bonds, nitrogen usually forms three bonds, oxygen usually forms two bonds, and hydrogen only forms one bond.
explain why a less reactive halogen is isolated in the dichloromethane
Why isn't sodium hydroxide? In the reaction of Aldol reaction to form ethyl trans-cinnamate. Reactant are Benzaldehyde and ethyl acetate.
what products would expect to obtain in the reaction of alpha-naphthaldehyde with KOH? write a detailed reaction mechanism.
What is the concentration of the vitamin C standard solution? Using a balance, 125mg of Vitamin C was weighed out and was added to a 100-mL beaker and dissolved in 50mL of DI water.
When cyclopentane is exposed to Br2 in the presence of light, reaction occurs. Write the formulas of all possible monobromination products. Draw molecule by placing atoms on grid.
a 12.6 g sample of NH4NO3 is dropped into a constant-pressure calorimeter containing 175 g of water at 23.5 C. What temperature will the water reach, assuming that the calorimeter container does not gain or lose any heat?
Two of the isomers have C-C-C bond angles that deviate significantly from those predicted by VSEPR theory. On this basis, which isomer would you predict is the least stable one? the second least stable?
