Why are almost all ionic compounds solid at room temperature?

Answers

Answer 1

Ions in ionic compounds create a lattice by strong electrostatic forces of attraction. They therefore exist at normal temperature as solids.

A chemical compound known as an ionic compound in chemistry is one that contains ions bound together by the electrostatic forces known as ionic bonding.

Despite having both positively and negatively charged ions, or cations and anions, the molecule is generally neutral.

These can be either polyatomic species, like the ammonium (NH+ 4) and carbonate (CO2 3) ions in ammonium carbonate, or simple ions, like the sodium (Na+) and chloride (Cl) in sodium chloride. Since individual ions in an ionic compound typically have more than one nearest neighbor, they are not thought of as belonging to molecules but rather as components of an ongoing three-dimensional network.

When solid, ionic substances typically have crystalline structures.

which one of the following statements about the wave described in the problem introduction is correct?

Answers

The problem's introduction's description of the wave, which is going in the +x direction, is accurate.

How can you know if a wave is moving left or right?

Due to the particles just on left side of the wave going upward and approaching their peak, the wave is traveling to the left. Alternatively, if the particles just on right are traveling up and the particles just on left are moving down, the wave is moving to the right.

What waves moving to the left and right?

When a wave's disturbance travels perpendicular to the wave's direction, the wave is said to be transverse. While the disturbance swings up and down, you might imagine the wave going from left to right.

Answers

The organic product formed when 1−hexyne is treated with H₂O, H₂SO₄, and HgSO₄ will be 2-hexanone (structure attached).

This reaction is an example of an oxymercuration reaction of the organic product 1−hexyne.

Oxymercuration is shown in three steps to the right. The nucleophilic double bond attacks the mercury ion, releasing an acetoxy group. The mercury ion's electron pair attacks carbon on the double bond, generating a positive-charged mercuronium ion. Mercury's dxz and 6s orbitals give electrons to the double bond's lowest unoccupied molecular orbitals.

In the second stage, the nucleophilic H₂O attacks the highly modified carbon, freeing its mercury-bonding electrons. Electrons neutralize mercury ions by collapsing. Water molecules have positive-charged oxygen.

In the third stage, the negatively charged acetoxy ion released in the first step attacks the hydrogen of the water group, generating the waste product HOAc. The two electrons in the oxygen-hydrogen link collapse into oxygen, neutralizing its charge and forming alcohol.

How does oxidation number work?

The number of electrons that a specific atom or ion has either gained or lost in comparison to a neutral atom is known as the oxidation number. The oxidation number of a free element is always zero. Since the compound loses electrons when it is oxidized, the meaning was enlarged to include further reactions in which electrons are lost, regardless of the presence of oxygen.

A free element's oxidation number is always zero.

A monatomic ion's charge and oxidation number are the same.

Hydrogen (H) has an oxidation number of 1, but when mixed with fewer electronegative elements, it becomes negative.

In most compounds, oxygen (O) has an oxidation number of 2, but peroxides have a -1.

A Group 1 element's oxidation number in a compound is one.

In a compound, a Group 2 element's oxidation number is +2.

A Group 17 element in a binary compound has an oxidation number of 1.

The light observed in a flame test is the emission that occurs when an electron moves from a higher energy level to a lower energy level.

This occurs because the electron loses energy in the form of light as it moves from one energy level to another. The light emitted is dependent on the type of cation that is present in the flame. Different cations will emit different wavelengths of light due to their unique energy levels.

This is why a flame test is used to identify different elements and compounds. Additionally, infrared (IR) radiation is also emitted by the cation in the flame.

if two equilibrium reactions are added together, what is the relationship between the equilibrium constants for the individual reactions and that for the overall reaction?

Answers

The equilibrium constant for overall reaction is the product of the equilibrium constant of the added reaction.

If two equilibrium reactions are added together,  the relationship between the equilibrium constants for the individual reactions and overall reaction is the equilibrium constant for overall reaction is the product of the equilibrium constant of the added reaction.

the reaction is given as :

A + B ⇄ AB

K1 = [AB] / [A] [B]

AB + A ⇄ A₂B

K2 = [A₂B] / [AB] [A]

now the addition of two equation is given as :

2A + B  ⇄ A₂B

K overall = [ A₂B] / [A]² [B]

this means : equilibrium constant for overall reaction :

K overall = K1 K2

a chemist measured the amount of hydrogen bromide produced during an experiment. she finds that of hydrogen bromide is produced. calculate the number of moles of hydrogen bromide produced.

Answers

Molar mass of HBr  is 80.91194 g/mol.

Molar mass of Br = 79.904

molar mass of H = 1.00794

Molar mass of HBr = 79.904 + 1.00794 = 80.91194

The mass of a sample of a chemical compound divided by the quantity, or the number of moles in the sample, expressed in moles, is known as the compound's molar mass. The molar mass is a bulk property of a material rather than a molecular one. The compound is present in many different forms, each with a different mass as a result of the isotopes. The molar mass is the average of these masses. The molar mass is most frequently calculated using the standard atomic weights and is a function of the relative abundance of the constituent atoms' isotopes on Earth. It is thus a terrestrial average. The conversion between a substance's mass and amount can be done using the molar mass.

specify the number of protons, neutrons, and electrons in the neutral atom copper-64.

Answers

The neutral atom copper-64 has 29 protons, and 35 neutrons and 29 number of electrons.

The number of electrons, protons, and neutrons of an atom is known from the atomic notation. Atomic notation represents showing the atomic symbol, atomic number, and atomic mass. In some periodic tables of elements, the position of the mass number and atomic number can be written differently, but generally the mass number is written at the top and the atomic number is written at the bottom before the atomic symbol.

The mass number is the number of protons to the number of neutrons. The atomic number indicates the number of protons and the number of protons in a neutral atom equals the number of electrons.

The atom has the atomic symbol Cu (copper) with atomic number 29 and mass number 64. So, it can be concluded that Cu has 29 protons. The number of electrons is the same as the number of protons, namely 29. Meanwhile, the number of neutrons:

Mass number = number of protons + number of neutrons

64 = 29 + number of neutrons

Number of neutrons = 35

So, the number of electrons, protons, and neutrons in the atom is 29, 29, 35.

what would be the final pressure in a 5.0 l reaction vessel if 6 mol hydrogen gas completely reacts with phosphorus at 298 k?

Answers

If 6 mol of hydrogen gas completely reacts with phosphorus at 298 k, the final pressure in a 5.0 l reaction vessel is 20 atm. When a reaction occurs, P4(s) + 6H2(g)  => 4PH3 (g).

The force perpendicularly applied to an object's surface divided by the area over which it is dispersed is known as pressure. The gauge pressure, also known as gauge pressure, is the pressure in relation to the surrounding air pressure. To express pressure, a variety of units are employed. The chemical element phosphorus has the atomic number 15 and the letter P in its name. Phosphorus is an element that exists in two main forms, red and white phosphorus, but is never found on Earth as a free element due to its strong reactivity.

What is the oxidation number sulfur in H2S?

Answers

The oxidation number sulfur in H₂S is -2.

A compound's total number of oxidations must be zero.

The two hydrogen atoms in the chemical hydrogen sulfide, H₂S, each have an oxidation number of +1, making a total of +2. As a result, the compound's sulfur has an oxidation number of -2, and the total number of oxidations is 0.

Assume that the sulfur atom in H₂S has an oxidation number of x.

S be x.

Now,

2+x=0

⇒x=−2

What is oxidation number?

The total number of electrons that an atom either receives or loses in order to create a chemical connection with another atom is known as the oxidation number, also known as the oxidation state.

Depending on whether we are taking into account the electronegativity of the atoms or not, these phrases can occasionally have a distinct meaning. Coordination chemistry commonly makes use of the phrase "oxidation number."

What distinguishes an oxidation number from an oxidation state?

In contrast to the oxidation state, which indicates how oxidised an atom is in a molecule, the oxidation number describes the charge that the core metal atom will retain once all ligands have been removed.
