Suppose helium nuclei has exactly the same mass as adding two single protons and neutrons, the Sun's luminosity would be
a. much greater than its current value
b. much lower than its current value
c. roughly the same
react 3-methyl-2-butanol with HBr. Predict the products and explain why the experiment will not be as successful for production of an alkyl bromide as the reaction of 1-butanol with HBr.
It takes 580. J of energy to raise the temperature of 124.5 g mercury from 20.0°C to 53.5°C. Calculate the specific heat capacity and the molar heat capacity of mercury.
The (-) enantiomer of a compound has a specific rotation [a]= -86 degrees. A sample of this pure enantiomer, when measured in a two dm sample tube, gives an observed rotation
calculate the amount of heat necessary to raise the temperature of 53.4 grams of ice at -50.0 degrees celsius to water
The fact that boiling point of a pure solvent is lower than the boiling point of a solution of the same solvent is a direct consequence of the. freezing-point depression of the solution.
The effective nuclear charge, Zeff, for a valence electron can be approximated using the "core charge" of the atom, that is, the total charge of the nucleus and the inner (non-valence) electrons.
