Answer:

The nucleus has an overall positive charge as it contains the protons.

Explanation:

Every atom has no overall charge (neutral). This is because they contain equal numbers of positive protons and negative electrons. These opposite charges cancel each other out making the atom neutral.

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).

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.

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.

1. Atomic Radius:

  Atomic radius increases down a group and decreases across a period. Lithium (Li) has a larger atomic radius than beryllium (Be) due to Li's additional electron shell. Be has fewer shells, resulting in a smaller radius.

2. 2nd Ionization:

  Second ionization energy is the energy needed to remove a second electron. Potassium (K) has higher second ionization energy than calcium (Ca) due to K's electron configuration ([Ar] 4s¹), requiring breaking into a filled shell.

3. C-C Bond:

  Carbon-to-carbon bond energy differs based on bond type. Ethene (C₂H₄) has a stronger double bond, requiring more energy to break, while ethane (C₂H₆) has a weaker single bond.

4. Boiling Point:

  Boiling points relate to intermolecular forces. Chlorine (Cl₂) has lower boiling point due to weaker dispersion forces compared to bromine (Br₂), with stronger dispersion forces leading to higher boiling point.

Answer:

Un par solitario o par de electrones no compartidos es un par de electrones de valencia que no se encuentra formando un enlace, ni compartido con otros átomos. Cuando un átomo se agrupa con otros para formar una molécula, sus electrones más externos -también conocidos como electrones de capa de valencia- dejan de pertenecer únicamente al átomo del que provienen, pasando a pertenecer a la molécula formada. Los orbitales atómicos de valencia dejan de existir como tales y pasan a formar orbitales moleculares con características diferentes a las originales. Como los pares solitarios se encuentran en la capa más externa de los átomos, cuando estos átomos forman moléculas pasan a formar parte del conjunto de electrones de valencia de la molécula. De esto se deduce que los pares solitarios son, de hecho, un subconjunto de los electrones de valencia de la molécula a la que pertenecen.

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.

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:

Explanation:

To solve for number one we must follow these steps:

m = 703.55 g − 345.8 g

m = 357.75 g

Then we solve for the density-

d = 357.75 g / 225 mL

d = 1.59 g/mL

Answer for number 5) 1.59 g/mL

Density= Mass/Volume

therefor- Mass = 65.14g and Volume = 35.4mL

Density = 65.14g/35.4 mL = 1.84 g/mL

Answer for number 6) 1.84 g/mL

Question 7-

g = (0.8765 g/mL)(250.0 mL) = 219.1 g

Answer: 219.1 g

Question 8-

Density = mass/volume

Mass = 1587g

4.5cm x 5.2cm x 6cm = 140.4 cubic-cm

Volume = 140.4 cubic-cm

Mass/volume = 1587/140.4 = 11.3 g/cm^3

Answer: 11.3 g/cm^3

Question 9:

First calculate the volume of iron

49.10mL − 45.50mL = 3.60mL

Density = mass/volume;

density = 28.5g/3.60 mL= 7.92 g/mL

Answer: 7.92 g/mL

Question 10:

Volume = 2500.0g / 10.5g/cm3 = 238.095cm^3

Now we round up the answer to 238cm^3

Answer: 238cm^3

The correct statement which has the same empirical formula as molecular formula is "CH3COOH".

A chemical compound's empirical formula is a representation of the simplest whole number ratio between its constituent parts.

The molecular formula is a depiction of the compound's actual whole number ratio between its constituent parts.

To put it another way, molecular formulas tell you how many atoms of each element are in a compound, whereas empirical formulas tell you the simplest or most reduced ratio of components.

Acetic acid has the molecular chemical formula CH3COOH. In the order C: H: O, the true whole number ratio is 2: 4: 2. In the order C: H: O, the smallest simple whole number ratio is 1: 2: 1. As a result, acetic acid's empirical formula is CH2O.

Hence, the correct option is A.
