As ocean depth increases, _____. temperature increases density decreases salinity increases pressure decreases
Rufina [12.5K]

Answer:

The correct option is: salinity increases  

Explanation:

Ocean is a large water body that is a division of the World Ocean. An ocean is divided into various vertical zones based upon the physical and biological conditions.

The halocline zone is characterized by a <u>rapid increase in the salinity with the increase in the depth.</u> Thus resulting in decrease in the temperature of maximum density with the increase in salinity.

A chemist examines an ionic compound that contains magnesium and one other element. She
Igoryamba

Group 7

Explanation:

The unknown element belongs to the seventh group on the periodic table of elements.

Ionic bonds are usually formed between metals and nonmetals. They formed by the transfer of electrons from the less electronegative specie to the more electronegative one.

The metals usually lose electron because they are highly electropositive species.

  • If we have a magnesium atom with two valence electrons.
  • To form ionic bonds, it must transfer the two electrons to another atom.
  • The other atom, a nonmetal must be ready to accommodate and receive the donated electrons.
  • This ensure that its own octet is complete.
  • Group 6 elements requires 2 electrons to have a complete octet.
  • They can receive the two electrons

But we were told that there are two atoms of that element for each of the magnesium atom;

  the atom must have a capacity of collecting one electron each to be stable.

Such atoms are found in Group 7 on the periodic table.

Jill is studying the temperature output of an ammonium chloride hand warmer with a calorimeter. What change should she expect to
ANEK [815]

Answer:

The water will continue to heat up as the experiment progresses.

Explanation:

When a person's fingers are cold or has a muscles ache, one can use chemical hand warmers to heat them up. There are two types of chemical hand warmer products, and they all depend on exothermic chemical reactions to work.

However, ammonium chloride dissolution is endothermic but its crystalization is exothermic. When used as a hand warner with a calorimeter, it is found that the temperature of the water increases steadily due to the crystalization of the ammonium chloride. Hence the answer.
