Answer:

The behavior of molecules in different phases of matter represents a balance between the kinetic energies of the molecules and the attractive forces between them. All molecules are attracted to each other. The molecules are in the solid-state. At higher temperatures, the kinetic energy of the molecules is higher.

Molecules are the various elements linked together and are present in the matter. The molecules in different phases of matter are represented by kinetic energies and attractive forces.

The kinetic molecular theory of matter elucidates the composition of the matter of particles of tiny size. The theory explains matter like gas, liquids, and solids.

The different states of matter explain the constant movement and negligible intermolecular force and volume of the particles. The particle matter is said to undergo elastic collision.

The molecules of solids have low kinetic energy whereas the molecules of liquids and gases show high kinetic energy as the particles are placed at larger distances.

Therefore, the state of matter affects the behavior of molecules.

Taking into account the definition of ionization energy, the correct answer is option c: greater than 735 kJ/mol.

Electrons are held in atoms by their attraction to the nucleus, which means that energy is needed to remove an electron from the atom.

Ionization energy, also called ionization potential, is the necessary energy that must be supplied to a neutral, gaseous, ground-state atom to remove an electron from an atom. When an electron is removed from a neutral atom, a cation with a charge equal to +1 is formed.

The further away the electron is from the nucleus, the easier it is to remove it, that is, the less energy is needed.

The second ionization energy represents the energy required to start a second electron. Its value is always greater than the first ionization energy because the volume of a positive ion is less than that of the neutral atom and the electrostatic force is greater in the positive ion than in the atom.

In other words, the energy required to remove a second electron is called the second ionization energy, and due to the difficulty of removing an electron from a positive particle, its value is greater than that of the first ionization energy.

Finally,  the correct answer is option c: greater than 735 kJ/mol.

Answer:

In redox reactions, electrons are transferred from one species to another. If the reaction is spontaneous, energy is released, which can then be used to do useful work. To harness this energy, the reaction must be split into two separate half reactions: the oxidation and reduction reactions. The reactions are put into two different containers and a wire is used to drive the electrons from one side to the other. In doing so, a Voltaic/ Galvanic Cell is created.

Explanation:

When a redox reaction takes place, electrons are transferred from one species to the other. If the reaction is spontaneous, energy is released, which can be used to do work. Consider the reaction of a solid copper (Cu(s)) in a silver nitrate solution (AgNO3(s)).

he AgNO3(s) dissociates in water to produce Ag+(aq) ions and NO­­−3(aq) ions. The NO3-(aq) ions can be ignored since they are spectator ions and do not participate in the reaction. In this reaction, a copper electrode is placed into a solution containing silver ions. The Ag+(aq) will readily oxidize Cu(s) resulting in Cu2+(aq), while reducing itself to Ag(s).

This reaction releases energy. When the copper electrode solid is placed directly into a silver nitrate solution, however, the energy is lost as heat and cannot be used to do work. In order to harness this energy and use it do useful work, we must split the reaction into two separate half reactions; The oxidation and reduction reactions. A wire connects the two reactions and allows electrons to flow from one side to the other. In doing so, we have created a Voltaic/ Galvanic Cell.

Answer:

Brick

Explanation:

Answer:

Explanation:

Brick has a heat capacity of 840 J/kg degree Centigrade.

That means that if you have 1 kg of brick, you will need to add 840 joules of heat to get it to go up 1 degree C.

The heat capacity of iron is 450 J/kg (degree centigrade).

Brick has the higher heat capacity. Undefined in all of this is a joule. It is a work unit. The problem is that to define a joule accurately, you need to bring in a lot of other units. Content yourself by understanding that both the iron and the brick are measured in the same units -- Joules.

Explanation:

Oxygen has atomic number eight. This means that the nuclei of all oxygen atoms have eight protons. A neutral oxygen atom will also have eight electrons. In an oxygen ion with a 2− charge, the number of protons is still 8, but the number of electrons is 10.

Hi, the answer is 3510g

Step-by-step explanation:-

We know that density of a substance tells us the mass of exactly one unit of volume of given substance. In this question,

Aluminium density = 2.70g/mL

So,

V = L x W x H = 1300 cm³ = 1300 mL

m = D x V = (2.70 / 1300) = 3510g

I lil one nice to meet you and how is your day

Answer:500 ml

Explanation:

M1 = 0.5

V1 = 100 ml

M2 = 0.1

V2 =??

M1 * V1 =M2 * V2

0.5 M * 100 ml = 0.1 M *V2

V2 =0.5 M * 100 ml /0.1 M

V2 = 500 ml

Answer:  A, 1.98x10^24 atoms of H

Explanation:  39.0 g of sulfur = (79.0g/32.1 g/mole) = 2.46 moles S

The balanced equation promises we'll get 2 moles H2O for every 3 moles  ofS, a molar ratio of (2 moles H2O)/(3 moles S)

(2.46 moles S)*[(2 moles H2O)/(3 moles S)] = 1.64 moles H2O

(1.64 moles H2O)*(6.02x10^23 molecules H2)/mole H2O)*(2 H atoms/H2O molecule) =  1.97x10^24 atoms of H

Answer:

Density = Mass/Volume

Answer:

Group1 elements will react with groupvi element in the ratio

1:2

Group ( 1 ) elements react with group ( vi ) elements​ in 1 : 2 ratios.  Group ( 1 ) elements are alkali metals and group ( vi ) elements are chalcogens.

A chemical element is a species of atoms, including the pure material made entirely of that species, that have a specific number of protons in their nuclei.

Chemical elements, in contrast to chemical compounds, cannot be reduced by any chemical process into simpler molecules. All living and non-living things are made up of elements, which are fundamental building blocks.

They serve as the universe's center. Elements make up every particle, no matter how little or large. The five primary elements that make up our body are carbon, hydrogen, oxygen, nitrogen, and calcium.

Thus, Group ( 1 ) elements react with group ( vi ) elements​ in 1 : 2 ratios.
