Answer:

The answer to your question is below

Explanation:

Elements Compounds

1.- Cu (Copper) NaCl (sodium chloride)

2.- Ag (Silver) HNO₃ (nitric acid)

3.- Al (aluminum) KOH (potassium hydroxide)

They are similar because that are composed by elements, they are different because elements are composed by only 1 element and compounds are composed by 2 or more elements.

Elements are simple and compounds are more complex structures.

Answer: elements are gases: hydrogen (H2), nitrogen (N2), oxygen(O2), fluorine (F2), chlorine (Cl2), helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) and radon (Rn).

Explanation:identify three elements and three compounds. ... They are similar because they are both pure substances but they are different because compounds have two or more different types of atoms while elements have the same exact type of atoms.

Answer : The ratio of the mass ratio of S to O in SO to the mass ratio of S to O in SO₂ is 2.

Explanation :

Law of multiple proportion : It states that when two elements can combine to form two or more different compounds then the mass of one element compared to fixed mass of the other will always be in a ratio of small whole numbers.

As we know that,

Mass of oxygen = 16 g

Mass of sulfur = 32 g

Mass of sulfur in SO = 32 g

Mass of oxygen in SO = 16 g

Mass ratio of Sulfur to oxygen in SO = $\frac{\text{Mass of sulfur}}{\text{Mass of oxygen}}=\frac{32g}{16g}=2$ .....(1)

and,

Mass of sulfur in SO₂= 32 g

Mass of oxygen in SO₂ = (2 × 16)g = 32 g

Mass ratio of Sulfur to oxygen in SO₂ = $\frac{\text{Mass of sulfur}}{\text{Mass of oxygen}}=\frac{32g}{32g}=1$ .....(1)

Ratio of S and O in SO = 2 : 1

Ratio of S and O in SO₂ = 1 : 1

Taking ratio of 1 and 2, we get:

$\frac{\text{Mass ratio of Sulfur to oxygen in SO}}{\text{Mass ratio of Sulfur to oxygen in }SO_2}=\frac{2}{1}=2$

Hence, the ratio of the mass ratio of S to O in SO to the mass ratio of S to O in SO₂ is 2.

You are given both the energy level, n = 4, and the subshell, l = 3 on which the electrons reside.

The subshell is given to you by the angular momentum quantum number, l which can take value that ranges from 0 to n − 1

l = 0 → the s-subshell

l = 1 → the p-subshell

l = 2 → the d-subshell

l = 3 → the f-subshell

<u>For n = 4 and l = 3, ml can be -3, -2, -1, 0, +2, +2, and +3. </u>

<u>Each of these can have 2 electrons (+1/2 and -1/2 spin) for a total of 14 electrons.</u>
