Which property determines whether a substance is a solid or liquid at room temperature?

Answers

Answer 1

Answer:

1. The kinetic energies of the particles (atoms, molecules, or ions) that make up a substance. Kinetic energy tends to keep the particles moving apart.

2. The attractive intermolecular forces between particles that tend to draw the particles together.

The statement "it is not the union that organizes the employees; it is management " means that :

The management creates the climate which allows the union to convince employees to accept union representation.

This excerpt shows that although the union helps in the organization of employees for better and easy management of staffs by the management, the management creates an enabling environment by creating stipulations which allows the u ions to convince staffs to join and accept union representation in staff welfare matters.

Hence we can conclude that, the management creates the climate which allows the union to convince employees to accept union representation.

Would you expect the shielding effect to be greater in bromine than in chlorine?
A. Yes, because there are more filled orbitals in bromine.
B. Yes, because bromine has a higher atomic number.
C. No, because they are both in the same family.
D. No, because chlorine has a higher electronegativity than bromine.

Answers

The shielding effect of bromine is greater than chlorine because there are more filled orbitals than in chlorine.

Shielding Effect

This is the process where by electrons are protected by the pull attraction of the nucleus with the use of electron shells. The shielding effect increases down the group of the periodic table and increases across the period. This is because when you move down the group, there's an increase in the number of shell by 1 and it helps to reduce the effect of nuclear attraction on the electrons. However when you move across the period, there's an increase in the numbers of electron with the same shielding electrons from group 1(a) across the period to group 7(a).

Factor that affect the shielding effect of an electronThe numbers of electrons on the inner shells.Type of orbital which the electron is located.

Shielding effect is primarily dependent on the numbers of electrons in the inner shells as well as the type orbitals.

Would an alkaline earth metal make a good replacement for tin in a tin can?

Answers

Answer:

Definitely not. This is because the alkaline earth metal [basically group 2 elements] are reactive and will react with the contents of the can, contaminating it.

No, alkaline earth metals would not be a good replacement for tin in a tin can because alkali from alkaline earth metals react with tin and release hydrogen.

What are alkaline earth metals?

Alkaline earth metals are present in group 2 of the periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).

They are called alkaline earth metals because their hydroxide and oxides are highly alkaline. Their metal oxides are found in the earth's crust.

These metals have 2 electrons in their outer shell, and they are highly reactive, so they will react with the tin in a tin can.

Thus, alkali from alkaline earth metals react with tin and generate hydrogen, hence they would not make an acceptable replacement for tin in a tin can.

What are non-renewable energy sources?

Non-renewable energy sources are sources of energy that come from finite resources that cannot be replenished on a human timescale. They are called non-renewable because their reserves are being depleted faster than they can be replenished. These energy sources include:

Fossil fuels: Coal, oil, and natural gas are the three main types of fossil fuels. They are formed over millions of years from the remains of plants and animals that lived long ago. Fossil fuels are currently the most widely used sources of energy for electricity generation, transportation, and industrial processes.

Nuclear energy: Nuclear energy is produced through the process of nuclear fission, which involves splitting atoms of uranium or plutonium to release energy. Nuclear power plants generate electricity using this process.

Non-renewable energy sources are a major contributor to greenhouse gas emissions, which contribute to climate change. As a result, there is a growing need to transition to renewable energy sources that are sustainable and have a lower environmental impact.

Looking at the table, Silver is definitely the most conductible metal there. It has the lowest electrical resistivity which means it allows for an easier flow of electrons, and it also has a higher thermal conductivity which means it would exhibit a higher conductivity. Diamond has the highest thermal conductivity, but the electrical resistivity is extremely high and due to its giant covalent/tetrahedral molecular structure (being an allotrope of Carbon), electrons can't necessarily jump around. Diamond wouldn't be a conductor at all.

The most simplest composition and structures provide a higher thermal conductivity. For example, with Diamond, we know that it is a structure made of covalent bonds of carbon, so its thermal conductivity is high.

Answer:

Q1

Copper

Explanation:

Copper is a good conductor of electricity, its resistance is high, and its chemical activity is weak

Q2

The thermal conductivity of a specific material is highly dependent on a number of factors. These include the temperature gradient, the properties of the material, and the path length that the heat follows.

as the atoms of the elements from atomic number 3 to 9 are considered in sequence from left to right on the periodic table, the atomic radius of each successive atom is

Answers

Answer:

decreasing

Explanation:

from left to right the nuclear effective charge is increasing, attracting with a greater force the electrons and making the atom to reduces itd atomic radius

The atomic radius decreases along a period in periodic table.  Thus, from the third element Li to the 9th element fluorine, atomic radius decreases and F has the lowest radius among them.

What is atomic radius?

Atomic radius is the distance from the  nucleus to the valence shell. The atomic radius decreases from left to right in periodic table. Thus, the higher atomic radius is exhibited by metallic elements.

The horizontal rows in the periodic table is called periods. Along a period , atomic radius decreases and electronegativity increases. When moving to the right there is no increase in the number of shells and the filling of electrons does not achieve octet except for group 18. Hence, they are electronegative.

From atomic number 3 to 9 atomic number is decreasing. Hence, among these elements, the smallest one is fluorine (Z = 9).

How many grams of CO2 are produced using 0.29 moles of O2?

Answers

The mass of CO2 produced using 0.29 moles of O2 is 12.76 grams.

The reaction between carbon and pxygen atom is exprssed as:

C + O2 -> CO2

From he balanced equation, we can see that 1 mole O2 reacted to produce 1 mole of CO2.

Hence if 0.29 moles of CO2 was used in the reaction, the number of moles of CO2 produced will be 0.29 moles as well.

Mass of CO2 = number of moles * molar mass

Mass of CO2 = 0.29 * (12 + 32)

Mass of CO2 = 0.29 * 44

Mass of CO2 = 12.76grams

Hence the mass of CO2 produced using 0.29 moles of O2 is 12.76 grams.
