19. a geologist tests a rock containing calcium oxide by reacting it with hydrochloric acid. water and calcium chloride form.
which bonds break?
ca-o bonds in calcium oxide and h-o bonds in water
ca-o bonds in calcium oxide and h-cl bonds in hydrochloric acid
oh-o bonds in water and ca-cl bonds in calcium chloride
ca-cl bonds in calcium chloride and h-cl bonds in hydrochloric acid break

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.
