The arrangement of the species from best oxidizing agent to poorest oxidizing agent is:

  • Ag⁺
  • Ni²⁺
  • Fe²⁺
  • Al³⁺

<h3>What are oxidizing agents?</h3>

Oxidizing agents are agents which oxidizes other species but are themselves reduced.

Oxidizing agents accept electrons from electron donors.

Non-metals are good oxidizing agents.

The oxidization potential of metals increases with increasing positive values of reduction potential.

In conclusion, oxidizing agents accept electrons are themselves reduced.

Brenda rode a skateboard 95 meters west. It took her 20 seconds. What was
Artemon [7]

Answer:

D. 4.75 m/s west

Explanation:

You can immediately get the answer once you know the formula for<em> velocity.</em>

  • The formula for velocity is: Velocity (V) = \frac{distance (d)}{time (t)}

The distance is 95 meters while the time is 20 seconds. All you have to do is to divide <u>95 meters by 20 seconds</u>.

Let's solve:

  • V = \frac{d}{t}
  • V = \frac{95 meters}{20 seconds}
  • V = 4.75 meters per second

Since Brenda is going west with her her skateboard, then you have to add <em>west </em>as her direction.

Brenda's velocity is 4.75 m/s west.

David is making lemonade he asked you could you some lemon juice and water the sugar starts to dissolve what can we do to speed
suter [353]

We could (a) stir faster and (b) warm the mixture.

<em>Stirring faster</em> moves freshly-dissolved sugar away from the solid and allows new water molecules to contact with the surface,

<em>Warming the mixture</em> gives the water molecules more kinetic energy, so their collisions with the surface of the sugar will be more effective in removing the sugar molecules.

Which atom’s ionization energy is greater than that of phosphorus (P)? A. Ba B. K C. As D. Cl
WINSTONCH [101]

Answer is: D. Cl (chlorine).

The ionization energy (Ei) is the minimum amount of energy required to remove the valence electron, when element lose electrons, oxidation number of element grows (oxidation process).

Barium, potassium and arsenic are metals (easily lost valence electrons), chlorine is nonmetal (easily gain electrons).

Alkaline metals (in this example, potassium) have lowest ionizations energy and easy remove valence electrons (one electron), earth alkaline metals (in this example, barium) have higher ionization energy than alkaline metals, because they have two valence electrons.

Nonmetals (in this example chlorine) are far right in the main group and they have highest ionization energy, because they have many valence electrons.

How the moon surface is visible to an observer on earth
ehidna [41]

The moon surface is visible to an observer on earth due to the gravitational force that attracts the moon to the earth. The more massive the body is, the more the smaller body is attracted to the larger body. We can only see the side of the moon due to the speed at which the moon rotates.

How many atoms are in 4.0 x 10ˉ⁵ grams of Al?
igomit [66]

Answer:

8.9x10¹⁷ atoms of Al are present

Explanation:

To find the number of atoms from the mass of an atom we must convert, as first, the mass to moles using the molar mass of the atom (26.98g/mol For Aluminium).

Then, we must convert the moles to atoms knowing that 1mol = 6.022x10²³ atoms.

<em>Moles Aluminium:</em>

4.0x10⁻⁵g * (1mol / 26.98g) = 1.483x10⁻⁶ moles Al

<em>atoms:</em>

1.483x10⁻⁶ moles Al * (6.022x10²³ atoms / mol) =

<h3>8.9x10¹⁷ atoms of Al are present</h3>
