Answer:
X₃Z₂
Explanation:
A metal ion (X) with a charge of 2+ = X²⁺
nonmetal ion (Z) with a charge of 3- = Z³⁻
In a neutral compound, the charges but balance each other to remain neutral. However in this case, the charges are not balanced.
A simple way to make the charges balance is by tweaking the number of the ions present in the compound.
We do this by multiplying the metal ion with 3 and the non metal ion by 2.
That way we have;
Metal ion = 3X2⁺ (Total charge - 6⁺)
Non metal ion = 2Z3⁻ (Total charge - 6⁻)
The charges are now balanced. The formular of the compound is;
X₃Z₂
Answer:
- <u><em>Sodium fluoride</em></u>
Explanation:
A <em>solution </em>is constituted by two parts: the solute and the solvent (there may be more than 1 solute and more than 1 solvent, but that is not the key of the answer).
<em>Solute</em> is the substace that is dissolved and it is in less amount than the solvent.
<em>Solvent</em> is the substance that can dissolve the solute and it is a greater amount than the solute.
In the given solution:
- <em>sodium fluoride</em>, <em>85.0 mL</em>, is the solute,
- <em>water</em>, <em>350.0 mL</em> is the solvent, and
- the mixture of both substances is the solution.
The answer is gas and it involves the Kinetic molecular theory which is a model used to predict gas behavior. Molecules or atoms
Answer:
Desertification
Explanation:
Desertification is the process by which land becomes more desertlike and unable to support life. This happens when to many livestock overgraze an area.
True... atoms contain what are called electrons and protons. the protons being possitively charged and the elctrons being negatively charged
