When maleic acid is heated to 200 degrees C, it loses water and becomes maleic anhydride. Fumaric acid, a diastereomer of maleic acid, requires a much higher temperature before it dehydrates; when it does, it also yields maleic anhydride. Provide an explanation for these observations
1 liter of sodium carbonate 0.4 M is added to 1 liter HCl 0.3 M what is the excess material and how many moles remains?
At a particular temperature and 2.00x10^-2 M, concentration versus time data were collected for the reaction, and a plot of the natural log versus time resulted in a straight line with slope value of -2.97x10^-2 min^-1. Determine the rate law, int..
when a gold nugget with a mass of 521 g is added to 50.0 ml of water the water level rises to 77 ml what is the density of gold
A sample of ethanol (C2H5OH) has a mass of 43.8 g.(a) How many carbon atoms does the sample contain?
calculate the mass of silver chloride and dihydrogen monosulfide formed when 85.6 grams of silver sulfide reacts with excess hydrochloric acid.
What is the boiling point of a 0.800 molal solution of sugar in water? Kb = 0.512C/m for water. Sugar does not dissociate in solution and pure water boils at 100C.
Considering the Heisenberg's uncertainty principle, compute the uncertainty in the position of: a 1.50-mg mosquito moving at a speed of 1.40 m/s (if the speed is known to within a + or - 0.01 m/s)
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.
Heat is lost to the styrofoam calorimeter. Assuming a 6.22 C temperature change for the reaction of HCl(aq) with NaOH(aq), calculate the heat loss to the inner 2.35-g styrofoam cup. The specific heat of styrofoam is 1.34 J/gC.
