Molecules are mobile in a gas and some reactions can be run in the gas phase. Give several reasons solutions are preferable for synthetic reactions.
A sample of mercury(II) oxide is placed in a 5.00 L evacuated container and heated until it decomposes entirely to mercury metal and oxygen gas
Concentrated acetic acid is 17.5 M; vinegar is 0.87 M acetic acid. How much concentrated acid do you need to make 24 L of vinegar? Use the equation c1V1=c2V2 (where c = concentration and V = volume)
Assume that the heat required for the vaporization of the alcohol comes only from the aluminum block and that the alcohol vaporizes at 25°C.
The isomerization of cyclopropane follows first order kinetics. The rate constant at 700 K is 6.20*10^-4 min-1, and the half life at 760 K is 29 min. Calculate the activation energy for this reaction.
