Answer:

Element

Explanation:

<em>When atoms can't be chemically separated into simpler substances, they are an element.</em>

Alternatively: Oxygen can be found in the Periodic Table of Elements. Thus, it is an element.

All the other options (solution, mixture, compound and colloid) refer to different way in which two or more substances (be it elements or molecules) are together.

andreev551 [17]

Answer:

B. Thicker layer of blubber

Explanation:

For the leopard seals to survives this harsh environment, it must have a thicker layer of blubber

Blubber is a thick layer of fat. It is called the adipose tissues and found in most marine organisms.

  • This layer helps in insulating the body against heat loss.
  • By so doing, the animal is able to conserve internal heat.
  • They have low thermal conductivity and do not easily lose heat or gain heat as such.

The recommended daily allowance (RDA) of the trace metal magnesium is 410 mg/daymg/day for males. Express this quantity in μg/da
Ira Lisetskai [31]

Answer:

410mg/day *\frac{1000 ug}{1 mg}

Recommended daily Amount (RDA) of magnesium is  410,000 μg/day.

Explanation:

There are 1000μg in 1 mg and 1000 mg in 1g

1 mg=1000μg

The Recommended daily Amount (RDA) is 410 mg/day of magnesium. Converting 410 mg/day into μg/day

410mg/day *\frac{1000 ug}{1 mg}

It will become 410,000 μg/day

So Recommended daily Amount (RDA) of magnesium is  410,000 μg/day.

A student compares the boiling point of substances having different intermolecular forces. which dependent variable did the stud
Gwar [14]

A student compares the boiling point of substances having different intermolecular forces. <u>Boiling points of various substances</u> is the dependent variable that student most likely use.

<h3>Does the nature of intermolecular forces present in different substance affect their boiling points?</h3>

The boiling point of a substance is proportional to the strength of its intermolecular forces, the higher the boiling point, the stronger the intermolecular forces. We can compare the strengths of intermolecular forces by comparing the boiling points of different substances.

<h3>What properties are affected by intermolecular forces?</h3>

Intermolecular forces are measured by boiling points.

Intermolecular forces increase as bond polarization increases.

Ionic > hydrogen bonding > dipole dipole > dispersion is the order of the strength of intermolecular forces (and thus their impact on boiling points).

<h3>How can you determine strong and weak intermolecular forces?</h3>

Substances with strong intermolecular forces are very attracted to one another and are held together tightly. These substances require a great deal of energy to separate, whereas substances with weak intermolecular forces are held together very loosely and have weak interactions.
