A Formula is Always Neutral

Given : Formula of Compound is X₃Y₂

⇒ The Compound Contains Three X Ions and Two Y Ions

Given : The Charge on Each Y Ion is -3

⇒ The Charge on Two Y Ions = -3 × 2 = -6

As the Formula of Compound is Neutral, The Charge of 3 X Ions should be Equal to +6

⇒ 3X = +6

⇒ X = +2

⇒ The Charge on Each X Ion is +2

B is the Answer

2' A mixture containing 2.75 gof ammonium chloride (NH4cl) in 5.0 g of water was heated to dissolve the solid and then allowed t
Trava [24]

Answer:

55g NH₄Cl / 100g Water

Explanation:

Solubility of a substance define the amount of solute per solvent in a saturated solution. The solution can dissolve additional solute if heated.

In the problem, as the first crystal appears at 61°C the solubility in this temperature is the concentration of the solution, that is:

2,75g NH₄Cl / 5,0g water ₓ 100 = <em>55g NH₄Cl / 100g Water</em>

<em></em>

At a fixed pressure, if the temperature is doubled, the volume of a gas will be
Scrat [10]

Answer:

Doubled.

Explanation:

The relationship between the temperature and the volume of a gas at a constant pressure can be described using Charles' law:

  • V₁*T₂ = V₂*T₁

That means that the temperature and the volume of a gas are directly proportional: The higher the temperature, the higher the pressure. If one of those factors is increased twofold, the other one will be increased twofold as well.

The radii of the atoms become smaller from sodium to chlorine across period 3. This decrease is primarily a result of
Alexxx [7]

Answer:

Nuclear Charge

Explanation:

As we move from sodium to chlorine across, there's increase in atomic number (protons). This also means there is increase in the valence electrons (The valence electrons is denoted by the group).

As the number of protons increases, the nuclear energy also increases. Due to this, the electrons are attracted more strongly and pulled closely to the nucleus.
