What is the correct positions of the methyl group and the isopropyl group in the most stable chair confirmation of cis-1-isopropyl-2-methylcyclhexane
Show the boiling point of pure liquid A and B vapor curve, liquid curve The region where only liquid is present The region where only vapor is present The region in which an equilibrium between liquid and vapour exists.
A gas stream that contains 1.50 mole% CO2 flows through a pipeline. 20.0 kg/min of CO2 is injected into the line. A sample of the gas is drawn from a point in the line 10 meters downstream of the injection point and found to contain 2.3 mole% CO2.
Exactly 313.5J of heat energy will raise the temperature of 10.0 g of a metal to 60.0 C. IF the specific heat of the metal is 0.896J/gC, what was the initial temperature of the Metal

Consider two hypothetical elements, W and Z. Element W has an electron affinity of ?150 kJ/mol, and element Z has an electron affinity of ?38 kJ/mol.
A 12-gram mixture of methane, CH4, and ethane, C2H6, is completely combusted in oxygen. If the total mass of H2O produced is 23.4 grams, what was the approximate mass of the methane in the original mixture?
The Born-Haber cycle is a series of steps that represent the formation of an ionic compound from a metal and a nonmetal. For example, the steps in a Born-Haber cycle for the formation of NaCl(s) consist of sublimation of the metal Na atom
A 3.0 x 10-2 mg sample of a protein is dissolved in water to make 0.25 ml of solution. The osmotic pressure of the solution is 0.56 torr at 25C. What is the molar mass of the protein
Combustion of a 0.1000 g sample of a compound containing only carbon, hydrogen, and oxygen in excess yields 0.1953 g CO2, and 0.1000 g H2O. A separate experiment shows that the molar mass is 90 Daltons. Calculate the mass percent composition.
