The compound with the presence of higher inter-molecular forces has been Acetic acid. Thus, option A is correct.

The boiling point has been the temperature, at which the liquid has been started to convert to steam. The boiling has been mediated with the application of the energy to the substance for the breaking of the inter-molecular forces.

The higher the inter-molecular forces in the compound, the higher will be the boiling point of the compound. The higher concentration has also resulted in a higher boiling point.

In the following compounds, acetic acid has the highest boiling point of 118 degrees Celsius. Thus, it has been constituted of the higher inter-molecular forces. Hence, option A is correct.

The 3-dimensional orientation of a sublevel is known as atomic orbital.

In quantum mechanics, Atomic orbitals are locations around an atom's nucleus where electrons are most likely to be at any particular time(specific orbits). These specific orbits exist in levels and can be broken down into sublevels.

Each sublevel has an orbital and it is oriented differently in 3-dimensional space.

The atomic orbital is a mathematical function that depicts how one or two electrons in an atom behave as seen in waves.

Not every earthquake has a(n) Foreshock, but every earthquake has an Aftershock that occurs in the Same place as the mainshock.

An earthquake is defined as a natural disaster in which there are tectonic plates that are present on the earth's crust collides with each other.

An Earthquake can be minor as well as natural depending upon the frequency it causes the damage. Earthquake is the Shaking of Earth and was much destruction of the economy and manpower.

Surroundings are being disturbed like trees will fall, and buildings will collapse which will cause damage to the economy as well as to human life.

Foreshock is the before shop which happens before the earthquake and aftershock is the other socks that happen after the earthquake

Thus, the correct options are 1. Foreshock, 2. Aftershock, 3. The Same place as.

Explanation:

this will explain everything

Answer:

The first ionization energies (I1) of the alkaline earth metals are not as low as the alkali metals. The alkaline earth metals are therefore less reactive than the alkali metals (Be and Mg are the least reactive of the alkaline earth metals). Several physical properties of these elements are compared in Table 7.7.

Answer:

1. LiCi is formed by the treatment of lithium carbonate with hydrochloric acid

2. A combination reaction (also known as a synthesis reaction) is a reaction where two or more elements or compounds (reactants) combine to form a single compound (product).  

3. Chemical decomposition, or chemical breakdown, is the process or effect of simplifying a single chemical entity into two or more fragments.

4. A single-displacement reaction, also known as single replacement reaction or exchange reaction, is a chemical reaction in which one element is replaced by another in a compound

5. Double replacement reactions have two ionic compounds that are exchanging anions or cations.

6. The most electronegative elements are found on the top right of the periodic table.

7. cesium

8. Electronegativity describes the degree to which an atom attracts electrons in a chemical bond. But the electronegativity of two atoms would determine their bond type.

Answer:

136000 J or 136 kJ

Explanation:

Formula

Heat = m * c * deltaH

Givens

m= 0.5 kg

c = 3400 J / (kg * oC)

Deltat = (100oC – 20oC)

deltat = 80oC

Solution

Heat = 0.5 kg * 3400 J/(kg* oC) * 80oC

Heat = 136000 Joules

Heat = 136 kg

Answer:

Arrange them in order of greatest to least Molar Mass to get most dense to least dense at a given temperature and pressure.

Explanation:

"Given Temperature and Pressure" just tells you that those two variables are being held constant. The Ideal Gas Law (PV = nRT) shows that n (the # of moles) and V (the volume) are variable still. To keep pressure constant, we need to increase the volume so that the force per area is the same which would unfortunately lower the density. The only way for a gas to have the greatest density would be to have the least average kinetic energy to keep the pressure constant at a smaller volume. This is because kinetic energy is equal to KE = 1/2 m v^2, where m is mass in kilograms and v is the velocity. IT IS CRUCIAL TO NOTE THAT ACCORDING TO KINETIC MOLECULAR THEORY, ALL GASES HAVE THE SAME AVG. KINETIC ENERGY WHEN AT THE SAME TEMPERATURE. So since the avg. KE is also constant across these answers due to the temp. being constant, our only way to decrease the velocity (the rate at which the particles are moving per second) and in turn the number of collisions (to repeat, a smaller number of collisions is desired because they are equal to the pressure that must maintained at a constant value at the smallest volume possible to achieve highest density possible) is to increase the molar mass. This is also pretty intutive for the other part of the issue: since Density is a broken heart (m/v), a higher molar mass would ensure a smaller pressure (due to decreased velocity) and smaller volume (due to constant pressure). Okay, now order the gases heaviest to lightest in terms of molar mass and you got your answer. Please gimme brainliest if this helped bc it took 15 minutes to type out. Hope this helped you! :D

Density is an intensive property as it does not depend on the quantity of the substances Whereas mass and volume are extensive property. The order of density is carbon dioxide>Neon >argon>carbon-12> hydrogen.

Density tells about the compactness of the substances, how much dense is the substances in other words. Object that is more denser than water they just sink in the water.

Mathematically,

Density of gas  = Molar Mass of the gas  ÷volume occupied by the given gases

Density is directly proportional to molar mass of the gases.

Molar mass of argon = 18g/mole

Molar mass of Neon = 20g/mole

Molar mass of carbon dioxide=44.01 g/mol

Molar mass of hydrogen=1g/mol

Molar mass of carbon-12=12g/mol

The order of gases from most dense to least dense at a given temperature and pressure is carbon dioxide>Neon >argon>carbon-12> hydrogen.

Therefore, the order of density is  carbon dioxide>Neon >argon>carbon-12> hydrogen.

There are 1.9926 * 10 ^24 atoms.

Explanation:

M ( Mg ) = 80.45 g

We can find the molar mass of magnesium in the Periodic table:

M ( Mg ) = 24.31 g / mole

n = 80.45 g : 24.31 g/mole = 3.31 moles

N a ( Avogadro`s constant ) = 6.02 * 10 ^23

N = Na * n = 6.02 * 10 ^24 * 3.31 = 19.926 * 10 ^23

Explanation:

[tex]\Large \boxed{\sf by \ their \ properties}[/tex]

Every element has a set of particular characteristics. Each has a unique atomic and mass number because they contain a different ratio of protons and neutrons. The number of protons in an element mirrors the element's atomic number. The mass number equals the sum of the element's protons and neutrons.

According to increasing atomic numbers, chemical elements get organized. Periods and groups are the names of the horizontal rows and vertical columns, respectively. The chemical characteristics of elements within the same group are comparable due to their similar valency and number of outer electrons.
