if 1.500 g of solute that has a molar mass of 125.0 g were dissolved in 35.00 g of camphor, what would be the resulting freezing point of the solution?
The vapor pressure at 300 K is 856 torr. If 12.0 g of CCl3F is enclosed in a 1.0 L container, will any liquid be present? How much?
Consider the following reaction at equilibrium: 2CO2(g) 2CO(g) + O2(g) Change in H degree = -514kJ a) increase partial pressure of CO2 at equilibrium
chlorine gas can be prepared in the laboratory by the reaction of manganese dioxide with hydrochloric acid. how much
The burning of ethane produces both CO2 and H2O. If 200 mL of CO2 is produced at 20°C and 750 torr, what volume of water vapor would be produced at 24°C and 790 torr?
Provide a structure for the following compound: UV spectrum: ?max = 272 nm (? = 39,500); EI mass spectrum: m/z = 129 (molecular ion and base peak); IR: 2200, 970 cm-1;
This molecule has a charge of n-. By changing the overall charge, n, from 1- to 2- to 3- we get three different polyatomic ions. For each of these ions a) identify the central atom and b) determine the formal charge of the central atom, X.
Use resonance forms to show the delocalization (over four carbon atoms) of the negative charge of the benzyl and anion
calculate the mass of sodium nitrate required to produce 7.00 grams of oxygen according to the following reaction: 2NaNO3 = 2NaNO2 + O2
What is the theoretical mass of xenon tetrafluoride that should form when 130 g of xenon is reacted with 100 g of F2? What is the percent yield if only 145 g of XeF4 is actually isolated?
