A polar covalent bond between two atoms results from {Ans: two atoms that do not have similar electronegativities.}All of the following statements help to explain why water molecules form hydrogen bonds except: {Ans: Water is an electronegative molecule.}Which of the following helps most to explain why water has a high specific heat? {Ans: A water molecule can make 4 hydrogen bonds.}Water is a source of ______________ for chemical reactions in cells. {Ans: hydrogen atoms oxygen atoms}The table shown here lists the specific heat of several substances. Substance Specific heat J/g/∘C water 4.18 ethyl alcohol 2.44 benzene 1.80 sulfuric acid 1.40 Based on the information in the table, which of the following statements are true? {Ans: Sulfuric acid is less resistant to temperature change than water. Benzene is more resistant to temperature change than sulfuric acid. More heat is required to raise the temperature of 1 g of water 1 ∘C than to raise the temperature of 1 g of ethyl alcohol 1 ∘C. Water has a high specific heat due to the hydrogen bonding between water molecules.}Though you add heat, the temperature of boiling water remains constant because ... {Ans: it takes energy to
