When solid aluminum acetate (Aluminum Ethanoate) is put into water, it dissociates into its constituent ions, resulting in the following reaction:
Aluminum Acetate (solid) → Aluminum ions [tex]\rm (Al^3^+)[/tex] + Acetate ions [tex]\rm (CH_3COO^-)[/tex]
When solid aluminum acetate (also known as aluminum ethanoloate) is added to water, aluminum ions [tex]\rm (Al^3^+)[/tex] and acetate ions[tex]\rm (CH_3COO^-)[/tex]are produced. The attraction between the ions and the polar water molecules causes this separation. Hydration is the process through which water molecules surround these ions.
Due to the presence of freely moving ions that promote the flow of electric current, the resulting solution develops into a powerful electrolyte that can conduct electricity. Aluminum acetate dissociates and ionizes in water, which contributes to its function as a powerful electrolyte in aqueous solution and facilitates a variety of chemical and electrochemical reactions.

"what is the concentration in molarity of the solution formed when"
"at what gas temperature t e would the average translational kinetic energy of a helium atom be equal to that of an oxygen molecule in a gas of temperature 300 k"
The average translational kinetic energy of helium s equal to that of oxygen at [tex]\boxed{300\;{\text{K}}}[/tex] .
Further Explanation:
One of the states of matter is gas. In gases, the atoms and molecules have space between them and can easily move over each other hence gases are compressible. Gases neither have fixed shape nor volume. It occupies the shape and volume of the container. The examples of matter that are gases are nitrogen and carbon dioxide.
The kinetic theory is based on the following postulates:
1. Gas molecules have a large collection of individual particles with empty space between them and the volume of each particle is very small as compared to the volume of the whole gas.
2. The gas particles are in straight-line motion or random motion until they are not collided with the wall of the container or with each other.
3. The collision between the gas particles and the wall of the containers are an elastic collision that means molecules exchange energy but they don’t lose any energy during the collision. So the total kinetic energy is constant.
The formula to calculate the average translational kinetic energy of helium is as follows:
[tex]{{\text{E}}_{{\text{He}}}} = \frac{3}{2}{\text{k}}{{\text{T}}_{{\text{He}}}}[/tex] …… (1)
Here,
[tex]{{\text{E}}_{{\text{He}}}}[/tex] is the average translational kinetic energy of helium gas.
k is the Boltzmann constant.
[tex]{{\text{T}}_{{\text{He}}}}[/tex] is the absolute temperature of helium gas.
The formula to calculate the average translational kinetic energy of oxygen is as follows:
[tex]{{\text{E}}_{{{\text{O}}_{\text{2}}}}} = \frac{3}{2}{\text{k}}{{\text{T}}_{{{\text{O}}_{\text{2}}}}}[/tex] …… (2)
Here,
[tex]{{\text{E}}_{{{\text{O}}_{\text{2}}}}}[/tex] is average translational kinetic energy of oxygen gas.
k is the Boltzmann constant.
[tex]{{\text{T}}_{{{\text{O}}_{\text{2}}}}}[/tex] is absolute temperature of oxygen gas.
Since both gases have same average translational energy. So left-hand side of equation (1) and (2) becomes equal, and therefore right-hand side of both equations can be compared as follows:
[tex]\frac{3}{2}{\text{k}}{{\text{T}}_{{{\text{O}}_2}}} = \frac{3}{2}{\text{k}}{{\text{T}}_{{\text{He}}}}[/tex] …… (3)
Rearrange equation (3) to calculate [tex]{{\text{T}}_{{{\text{O}}_{\text{2}}}}}[/tex]
[tex]{{\text{T}}_{{{\text{O}}_2}}} = {{\text{T}}_{{\text{He}}}}[/tex] …… (4)
The value of [tex]{{\text{T}}_{{\text{He}}}}[/tex] is 300 K. So according to equation (4), [tex]{{\text{T}}_{{{\text{O}}_{\text{2}}}}}[/tex] also becomes 300 K.

Which of the two substances would have the higher boiling point ch4 or c?
Two of the substances in part 1 are ionic. which factors will result in a stronger ionic bond overall?
The factors that result in a stronger ionic bond are greater absolute charges and smaller ions. The similarity of ionic sizes can affect the bond's stability but doesn't directly make the bond stronger or weaker.
The following factors often affect an ionic bond's strength:
Greater absolute charges: Ionic bonds are more powerful when the positive and negative charges of the participating ions are greater. For instance, because the charges are higher in the former situation, the connection between a +2 ion (for instance, Ca²⁺) and a -2 ion (for instance, O₂) is stronger than between a +1 ion (for instance, Na⁺) and a -1 ion (for instance, Cl).
Ion bonds formed by smaller ions are frequently stronger. Ions can move closer to one another when they are smaller, which increases the electrostatic attraction between them.
Therefore, higher absolute charges and smaller ions produce an ionic bond that is stronger. Though it doesn't directly strengthen or weaken the binding, the similarity of the ionic sizes can have an impact on how stable the bond is.

A stronger ionic bond is characterized by larger ionic charges and smaller ion sizes, resulting in greater attraction and higher lattice energy. For instance, a 2+ cation would form a stronger ionic bond with a chloride ion than a 1+ cation due to the greater charge.
The factors that will result in a stronger ionic bond overall include the magnitude of the charges and the size of the ions. A stronger ionic bond is formed when the ions involved have larger charges because larger charges result in a greater electrostatic force of attraction. Additionally, smaller ions form stronger bonds since they can get closer together, which increases the attraction between them. The lattice energy is a measure of the strength of ionic bonding.
Sodium chloride is an example of a substance with ionic bonds that result in high melting and boiling points due to the strong attractions. The strength of an ionic bond is directly proportional to the quantity of the charges and inversely proportional to the distance between the charged particles. For instance, a cation with a 2+ charge would form a stronger ionic bond with Cl− than a cation with a 1+ charge because of the greater charge magnitude.
How many of the following species are paramagnetic? sc3+ br- mg2+ se?
Paramagnetic can be detected by the unpaired electrons in the electron configuration. In this case, out of Sc³⁺, Br⁻, Mg²⁺, and Se, only Se (Selenium) is paramagnetic because it has unpaired electrons.
Explanation:The substances in question are Sc³⁺ (Scandium ion), Br⁻ (Bromide ion), Mg²⁺ (Magnesium ion) and Se (Selenium). To determine if these species are paramagnetic, we need to look at their electronic configurations.
Sc³⁺ (Scandium ion) has an atomic number of 21. When it loses 3 electrons to form the cation Sc³⁺, it has the same electron configuration as Argon, with all shells filled, therefore it is diamagnetic, not paramagnetic.
Br⁻ (Bromide ion) is the ion formed when Bromine (atomic number 35) gains one electron. This results in a complete electron shell, and so bromide ion is diamagnetic, not paramagnetic.
The Mg²⁺ (Magnesium ion) is formed when Magnesium (atomic number 12) loses 2 electrons. This results in a complete electron shell, making this species diamagnetic as well.
Lastly, Se (Selenium) with an atomic number of 34 has 4 unpaired electrons in its ground state and therefore is paramagnetic.
So, out of Sc³⁺, Br⁻, Mg²⁺, and Se, only Se (Selenium) is paramagnetic.

Breaking solvent-solvent attractions and breaking solute-solute attractions : endothermic process
Forming solute-solvent attractions : exothermic process
Further explanationIn mixing the two solutions, it will require energy to break the attraction of each solution and create a new attraction that produces energy.
If both are equal then there will be no heat released or received so that the delta H solution is 0, which indicates that the solution is ideal
The ideal solution occurs if the attractive force between the molecules is the same as the attractive force of each solute and solvent
There are 2 kinds of deviations from Raoult's Law,
1. Positive deviation
Occurs if the attractive strength between each mixture forming agent is stronger than the attractive in the mixture
(X-X, Y-Y> X-Y)
This deviation produces a positive enthalpy of solution (ΔH +) which is endothermic
2. Negative deviationOccurs if the attractive force in the mixture is stronger than the attractive force of each substance
(X-Y> X-X, Y-Y)
This deviation produces an enthalpy of a negative value solution (ΔH -) which is exothermic
So that breaking solvent attractions and breaking attraction solutes require energy so it is called an endothermic process
While forming solute-attraction attractions will release heat so-called exothermic process
