Compound Y dissolves in ethanol but not water what type of bond is Y ?
Covalent Bond.
Explanation: Covalent compound are soluble in organic solvents (non polar) but insoluble in water (polar).
Ethanol being both polar and non polar can dissolve covalent compound.
If a car is moved 10 meters and 3 Newton's of force is needed to move the car, what amount of workhas
been done?
Work required = 30J
This is because work = F * x
F (Newton's force) = 3N
x (car moved) = 10m
Work = 3 * 10 = 30J

Chlorine and oxygen form many different compounds, including CIO, and Cl2O3. How do the names of these compounds differentiate one chlorine oxide from another?
Answer:
We can mix two compounds and create a third that bears little resemblance to its parents. For instance, by mixing two parts of hydrogen gas with one of oxygen - liquid water is formed. We should not be misled by the fact that chlorine and chlorine dioxide share a word in common. The chemistries of the two compounds are completely different.
Chlorine and chlorine dioxide are both oxidizing agents (electron receivers). However, chlorine has the capacity to take in two electrons, whereas chlorine dioxide can absorb five. This means that mole for mole, ClO2 is 2.6 times more effective than chlorine.
If equal, if not greater importance is the fact that chlorine dioxide will not react with many organic compounds, and as a result, ClO2 does not produce environmentally dangerous chlorinated organics. For example; aromatic compounds have carbon atoms arranged in rings and they may have other atoms, such as chlorine, attached to these rings, to form a chlorinated aromatic - a highly toxic compound that persists in the environment long after it is produced.
Chlorine dioxide's behaviour as an oxidizing agent is quite dissimilar. Like ozone, the predominant oxidation reaction mechanism for chlorine dioxide proceeds through a process known as free radical electrophilic (i.e. electron-attracting) abstraction rather than by oxidative substitution or addition (as in chlorinating agents such as chlorine or hypochlorite). This means that chlorinated organic compounds such as THMs and HAAs are not produced as a result of disinfection using chlorine dioxide
Hope this helps, have a nice day! :D
The way that the names of these compounds show that the Chlorine oxides are different is by making reference to the number of individual molecules in the compound.
How are the chlorine oxides differentiated?The number of chlorine and oxygen molecules in each compound are used to name the compounds which ensures that they are differentiated.
ClO₂ is called "Chlorine Dioxide" which shows that there are two Oxygen atoms.
Cl₂O₃ is called "Dichlorine Trioxide" which shows that there are two Chlorine molecules and 3 Oxygen molecules.

A chemist has dissolved a certain substance in water. The chemist knows that more of the substance could be dissolved into the water before it stops dissolving. Therefore, the current solution is
.
Answer is: the current solution is unsaturated.
Unsaturated solution means that more of a substance can be dissolve.
For example:
Solubility of potassium chlorate (KClO₃) at 100 grams of water at 80°C is 37.5 g, that means that all 37.5 g is completely dissolves, this is the saturated solution.
If we add 20 grams of potassium chlorate in 100 grams of water, there is less solute than the saturated solution, so this is unsaturated solution.

Answer:
Copper
Explanation:
Copper has this electronic configuration.
You can count the total number of electrons
= 29
Cu is the 29 th in the periodic table.( atomic number = 29)
Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Therefore, the given electronic configuration represents copper element.
What is element?Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.
The systematic distribution of electrons in the various atomic orbitals is called its electronic configuration. The atomic number of copper is 29. The electronic configuration of copper is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹ 3d¹⁰. 1,2,3 represents the number of shells and s and represents the orbitals. The superscripts represents the number of electrons in each orbitals.

What element is being reduced in the following redox reaction? Cr(OH)4-(aq) ClO-(aq) → CrO42-(aq) Cl-(aq).
The element that is being reduced in the given redox reaction is Cl (Chlorine)
The given redox reaction is
Cr(OH)₄⁻(aq) + ClO⁻(aq) → CrO₄²⁻(aq) + Cl⁻(aq)
First, we will define the terms oxidation and reduction
Oxidation can be defined as an increase in oxidation number
Reduction is defined as a decrease in oxidation number
This means the element that is being reduced in the reaction would have a decrease in oxidation number.
Oxidation number of Cr in Cr(OH)₄⁻ is +3; and the oxidation number of Cr in CrO₄²⁻ is +6. This is an increase in oxidation number and it means Cr is being oxidized.
Oxidation number of Cl in ClO⁻ is +1; and the oxidation number of Cl in Cl⁻ is -1. This is a decrease in oxidation number and it means Cl is being reduced.
Hence, the element that is being reduced in the given redox reaction is Cl (Chlorine).

The first stage of the experiment is focusing only on the physical properties of acidic property.
What is physical property?A physical property would be any quantifiable attribute whose value describes the condition of a physical system. Changes in a system's physical attributes are able to characterize its transitions between brief states. Physical attributes are sometimes known as observables.
Physical characteristics are frequently classified as intense or extensive. An intense property is independent of the system's size or extent, as well as the amount of material in the item, whereas an extended property has an additive link. The first stage of the experiment is focusing only on the physical properties of acidic property.

1. Describe what happens when two substances at different temperatures come into contact. Describe how the
law of conservation of energy applies to this system.
Answer:
Explanation:
When two substances at different temperatures like into contact, the substance that is at higher temperature will transfer energy, in the form of heat, to the substance that is at lower temperature, until their temperatures get equal.
In this case, if the two substances are isolated of the rest of the universe, the law of conservation of energy states that the heat released by the substance initially at higher temperature is the same amount of heat gained by the substance originally at lower temperature.
