A compound can be treated like an element when balancing chemical equations when : A. when there is no change to the atoms in the compound

If they remain together during the reaction, you can treat a compound as a singe atom.

hope this helps

Answer: Option (A) is the correct answer.

Explanation:

When two or more elements combine chemically to each other then it results in the formation of a substance known as a compound.

On the other hand, a substance that contains same atoms is known as an element.

For example, F_{2} is a diatomic molecule and since it contains more than one atom so it is a compound also.

Therefore, we can conclude that when there is no change to the atoms in the compound then a compound can be treated like an element when balancing chemical equations.

How are white blood cells linked to the lymphatic system?
Anon25 [30]

Answer:

The lymphatic system produces white blood cells, known as lymphocytes. There are two types of lymphocyte, T cells and B cells. They both travel through the lymphatic system. As they reach the lymph nodes, they are filtered and become activated by contact with viruses, bacteria, foreign particles, and so on in the lymph fluid.

Solutes dissolve in solvents to form a solution. A saturated solution contains just as must solute as it can normally hold.

The solvent in the coffee solution is water and the rest of the chemicals dissolved in the solvent are called solutes. A solution is formed when a solute is dissolved in a solvent.

A saturated solution contains just as much solute as it can normally hold at a particular temperature while a supersaturated solution contains more solute than it can normally hold at a particular temperature.

A polar molecule contains covalent bonds between atoms having an electronegativity difference above 0.5. Such molecules are polar as electrons of the bond are drawn closer to the atom that is more electronegative.

According to Avogadro's law; 6.02 × 10^23 particles is referred to as one mole of particles.

A strong acid has a pH that may range from 0 - 3. A strong base has a pH of around 10 - 14. Water is a neutral substance and has a pH of 7.

From the information provided;

Number of moles of acid = 0.002 moles

Volume of solution=  2 L

Concentration of solution = number of moles/volume = 0.002 moles/2L = 0.001 M

pH = - log[H^+]

pH = - log[0.001 ]

pH = 3

From;

pH + pOH = 14

pOH = 14 - pH

pOH = 14 - 8.5

pOH = 5.5

pOH = - log[OH^-]

[OH^-] = Antilog[-5.5]

[OH^-] = 3.2 × 10^-6 M

Answer:

<u><em>Pangaea</em></u>

<u><em>Alfred Wegner</em></u>

<u><em>plate tectonics</em></u>

Explanation:

What did Earth look like 250 million years ago? The continents of Earth were clustered together in formation that a scientist named<em> </em><u>Pangaea</u><u><em>.</em></u>The scientist that named "Pangaea" was a German scientist by the name of <u>Alfred Wegner.</u> He theorized that "Pangaea" split apart and the different landmasses, or continents, drifted to their current locations on the globe. Wegener's theories of plate movement became the basis for the development of the theory of <u>plate tectonics.</u>

Which element is most likely to form a cation? <br> sodium, silicon, sulfur, argon
Harrizon [31]
<h3>Answer:</h3>

Sodium

<h3>Explanation:</h3>
  • To answer the question we need to know a few things.

What are cations?

  • Cations are positively charged ions that are formed when an atom of an element loses an electron(s).

What elements form cations?

  • Metallic elements form cations since they react by losing electrons thus forming ions with a positive charge.
  • For example, alkali metals such as sodium form cations with a charge of +1.
  • In this case, sodium will form a cation with a charge of + 1, Na⁺

What are negatively charged ions?

  • Negatively charged ions are known as anions.
  • They are formed by non-metallic elements such as sulfur, argon, silicon, etc.
