Answer:

The answer to your question is d.

Explanation:

Chemical changes happen when the substance changes its original properties to form a new one. So option 1 is incorrect.

Dissolving a new substance does not form new substances as I mentioned before. The second option is incorrect.

The third option is also wrong because dissolving a substance does not separate anything.

The fourth option is correct, dissolving a substance allows us to make solutions.

Answer:

The correct options are:

Option C. separating solute particles from the mass of solute

Option D. making a solution

Explanation:

Dissolving of substances is simply a physical change as no new substance is formed and can easily be reversed.

Dissolving of substances does not create new chemicals, it only produces lesser concentration of the substance dissolved

Dissolving of substance results in the separation of the solute Particles as the particles are now free to move about. This is the reason why ionic compounds conduct electricity when in solution or molten state. E.g NaCl dissolves according to the equation

NaCl <==> Na+ + Cl-

So we can see that the particles (Na+ CL-) have separated from the solute itself

Dissolving of substances results in solution. This is true because the solute(substance that is dissolved) dissolve forming a homogeneous mixture call true solution

So, option C and D are correct.

All chemical reactions have a conservation of(1) mass, only(2) mass and charge, only(3) charge and energy, only(4) mass, charge,
Semenov [28]
All chemical reactions have a conversation of mass and energy. 

Because:- There are only two laws for conversation in a chemical reaction. The conversation of mass, no mass can be created nor destroyed. Also, the law of conversation of mass states that no energy can be created nor destroyed in a chemical reaction. The charge can obviously change because they can bond and change charges.

Calculate the molar concentration of the Cl⁻ ions in 0.65 M CaCl2(aq), assuming that the dissolved substance dissociates complet
alexandr1967 [171]
The question here is solved using basic chemistry. CaCl2(aq) is an ionic compound which will have the releasing of 2 Cl⁻ ions ions in water for every molecule of CaCl2 that dissolves.
CaCl2(s) --> Ca+(aq) + 2 Cl⁻(aq)
            [Cl⁻] = 0.65 mol CaCl2/1L × 2 mol Cl⁻ / 1 mol CaCl2 = 1.3 M
The answer to this question is [Cl⁻] = 1.3 M

Which of the following will most likely happen if you apply unbalanced forces to an object? It will change position. It will bec
Tasya [4]

It will change position.

For example, you are pushing a water bottle. The push is a force that is imbalance because there is no other force pushing the water back. So if you push the water bottle, it will move. When it moves, it is also call, "Changing position" because its location changed.

If ba+2 will reacts with n-3, the formula of the compound formed is:
Ivanshal [37]

If Ba^{+2} will reacts with N^{-3}, the formula of the compound formed is Ba_3N_2.

<h3>What is an ionic compound?</h3>

Ionic compounds are neutral compounds made up of positively charged ions called cations and negatively charged ions called anions.

Barium is a metal element and Nitrogen is a non-metal element, so they form an ionic compound. To make the formula of an ionic compound, first, we need to see the valence of the atoms, that is, how many electrons it can donate or it has to gain to have 8 electrons in the valence layer (octet rule).

Barium is in family 2, so it has two electrons in its valence layer, so it must donate these two electrons; Nitrogen is in family 15, so it has 5 electrons ins its valence layer and must gain 3 electrons.

Writing the ions they must form:

Ba^{+2}N^{-3}

First came the cation (positive charge), then the anion (negative charge), and the charges must change between them, without the signal, and will inform how many atoms are necessary for which element:

Ba_3N_2

Hence, If Ba^{+2} will reacts with N^{-3}, the formula of the compound formed is Ba_3N_2.
