Which statement about hydrogen bonding is true? select one:
a. hydrogen bonding is the intermolecular attractive forces between two hydrogen atoms in solution.
b. the hydrogen bonding capabilities of water molecules cause ch3ch2ch2ch3 to be more soluble in water than ch3oh.
c. hydrogen bonding of solvent molecules with a solute will not affect the solubility of the solute.
d. hydrogen bonding interactions between molecules are stronger than the covalent bonds within the molecule.
e. hydrogen bonding arises from the dipole moment created by the unequal sharing of electrons within certain covalent bonds within a molecule.

E.

Explanation:

All answers other than E have the incorrect bonding capabilities or other incorrect information.

D. They help water striders walk on water by creating surface tension.

Explanation:

I got a 100% on the unit test review EDG21

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
