The following information is given for ether, c2h5oc2h5, at 1atm: boiling point = 34.6 °c hvap(34.6 °c) = 26.5 kj/mol specific heat liquid = 2.32 j/g°c at a pressure of 1 atm, what is h in kj for the process of condensing a 22.0 g sample of gaseous ether at its normal boiling point of 34.6 °c?

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
