Organic chemistryWhen 2-butene reacts with hydrogen chloride gas, only one product is detected, whereas when 1-butene reacts similarly, two products are usually found. Explain this?
The density of germanium is 5.325 g/cm^3 . If you made a 4 nm quantum dot of germanium, how many atoms would it contain? Assume the dot is spherical.
What is the change in air temperature(, assuming the heat from the steam is all absorbed by air)
The reaction CH3CH2NO2 + OH- → H2O + CH3CHNO2- obeys the rate law d[A]/dt = -k[A][OH-], where A denotes CH3CH2NO2. It takes 0.5 min for one percent of the A to react at 25°C.
In a beaker, I mix 50 ml of 3 M HCl with 100 ml distilled water. Both fluids are at 25 C initially. (Cp mix =. 0.985 cal/g-C) a. what is the final T.
Calculate the voltage of the cell 2Ag+(aq) (0.200 M) + Cu(s) Cu2+(aq) (0.080 M) + 2Ag(s) Eocell = 0.460 V
A sample of gas inside a 150 mL piston has an initial temperature of 550 K and pressure of 8.0 atm. As the piston expands to 650 mL, the pressure decreases to 1.5 atm.
explain Why this separation occur and which solvent will be on top - the temperature of twenty degree Celsius. When hexane is added with H 2 O, there is a separation
Detremine the volume of CO2 produced at the temperature of 23 degree celsius and pressure of 0.985atm?
Elemental exonium (not a real element) consists of two major isotopes
A compound containing only carbon, hydrogen, and oxygen is subjected to elemental analysis. Upon complete combustion, a 0.9294-g sample of the compound
An experiment requires 46.0 of ethylene glycol, a liquid whose density is 1.114 . Rather than weigh the sample on a balance, a chemist chooses to dispense the liquid using a graduated cylinder.
how much heat is absorbed when 63.7g h2o at 100 c and 101.3 kpa is converted to steam at 100 c.
