What is the formula of the ionic compound formed between chlorine (Cl) and aluminum (Al)? AlCl, because aluminum loses three electrons and chlorine gains three electrons. AlCl3, because aluminum loses three electrons and chlorine gains one electron. ClAl, because chlorine gains one electron and aluminum loses one electron. ClAl3, because chlorine gains three electrons and aluminum loses one electron.

AlCl3, because aluminum loses three electrons and chlorine gains one electron.

Aluminium chloride is a salt with ionic bonds.  

Aluminium (metal from group 13) lost three electrons and form cation with postive charge 3+.

Chlorine (nonmetal from group 17) gain one electronand form anion with negatove charge.

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.
