Water

Question 1

why is water a dipole molecule

Answer 1

Uneven distribution of charge throughout
partially positive oxygen
partially negative hydrogen
ionic substances are attracted to the charges water has forming an ionic bond

Question 2

what bonds are formed between water molecules

Answer 2

hydrogen bonds

Question 3

what is the definition of a dipole

Answer 3

unequal distribution of electrons shared in an atom. has separate charges.

Question 4

what are the properties of water

Answer 4

good solvent (polar molecules can dissolve it it)
high specific heat capacity
liquid at room temperature
can be used in blood and xylem for transport

Question 5

what does hydrophobic and hydrophilic mean

Answer 5

hydrophobic- water hating (lipids/ fats) does not dissolve in water
hydrophilic- water loving ( salts/ ionic compounds) dissolves in water

Question 6

why does water have a high heat capacity and why is that an advantage

Answer 6

high specific heat capacity- large amounts of energy needed to break many hydrogen bonds
large inputs of energy cause small temperature rises
advantage since aquatic animals environments do not rapidly change + avoids body temperature changing rapidly
