In general terms, why do functional groups impart more chemical reactivity to families that have them? Why don't the alkanes display as many reactions as, say, the amines? Select all that apply:
Amines are Lewis bases and can be protonated.
Amines are Lewis bases and can be de-protonated.
Functional groups typically impart polarity to what would be an otherwise nonpolar hydrocarbon.
As the site of polarity, a functional group is a likely site of attack in polar or ionic reactions.
using a sample of gas having 1.47 mol at the temperature of twenty five degree celsisu exerts a pressure of 398 torr
Calculate the pH of a solution with the following: 5.12 moles of HCl are placed in a 3.00 L of water 4) Given the acid pKa is 4.76. Calculate the pH of a 0.35M acetic acid solution:
Uric acid dissociates as shown in the figure at the right with a pKa of 5.80, and can be treated as a simple monoprotic acid in this pH range. Its solubility in urine depends on the relative amount of protonated and unprotonated forms. A urine sam..

How many grams of butane must be burned to provide the heat needed to melt a 85.0-g piece of ice (at its melting point) and bring the resulting water to a boil (with no vapourization)? Assume a constant pressure of 1 bar and use the following data
2 NaHCO3(s) Na2CO3(s) + CO2(g) + H2O(g) Heating a 1.7184-g sample of impure NaHCO3 gives 0.196 g of CO2. What was the mass percent of NaHCO3 in the original 1.7184-g sample?
A 5.50 g sample of an unknown is dissolved in 251. g of benzene. The freezing point of the solution is 1.02 C below the normal freezing point of pure benzene.
The "air bags" in automobiles contain sodium azide, NaN3, which decomposes when activated by an electronic igniter to produce nitrogen gas that fills the bag.
what will be the equilibrium temperature when a 245 g block of lead at 300oc is placed in 150-g aluminum container
A 4.50-g sample of liquid water at 25.0 C is heated by the addition of 133 J of energy. The final temperature of the water is __________ °C. The specific heat capacity of liquid water is 4.18 J/gK.
