Answer:

Its a mixture.

Answer:

If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid.

The distance between the particles increases tremendously the attraction doesn't change.

Whilst water is boiled, the heat energy is transferred to the molecules of water, which begin to pass extra quickly. ultimately, the molecules have an excessive amount of power to stay connected as a liquid. while this takes place, they shape gaseous molecules of water vapor, which go with the flow to the floor as bubbles and tour into the air.

On heating, their kinetic electricity pushes neighboring atoms or molecules other than each different. This pushing of atoms or molecules outcomes in a slightly accelerated distance among molecules and the volume of stable additionally increases.

A sample of oxygen gas at STP is depicted in the diagram in the picture (4) of the image attached.

An oxygen molecule is a diatomic molecule, which is a molecule made up of just two atoms of the same element. The oxygen molecule in this instance is made up of two oxygen atoms.

If you have a lot of oxygen atoms at STP, they will spontaneously combine to produce O₂ because double bonds between oxygen atoms make their structure more stable.

If we carefully examine the figure in the attached image, we will see that it depicts a molecule made up of two atoms of the same element, which perfectly matches the definition of the oxygen molecule.

Therefore, this is shown in diagram (4), spontaneously combine to produce O₂  because double bonds between oxygen atoms make their structure more stable.

Answer:

The lattice energy decreases down the group and increases across the period, therefore, the lattice energy of LiF > lattice energy of LiI, and the lattice energy of NaCl < the lattice energy of AlCl₃

Explanation:

The given parameters are;

Compound [tex]{}[/tex]                                    Lattice Energy (kJ/mol)

LiF  [tex]{}[/tex]                                                     1030

NaCl  [tex]{}[/tex]                                                  788

MgCl₂  [tex]{}[/tex]                                                2326

LiI  [tex]{}[/tex]                                                       730

AlCl₃   [tex]{}[/tex]                                                  5376

Lattice is the energy that must be added in order to split one mole of a ionic solid compound into gaseous ions

Given that the force of attraction between charges is inversely proportional to the square of the distance separating the charges, we have that as the atomic radius increases progressively down the group, the lattice energy decreases, therefore, LiF which has a shorter inter nuclear distance than LiI due to fluorine, F, being higher up on the periodic table than iodine, I, has a greater lattice energy than LiI

Similarly, given that the atomic radius decreases across the period, and that sodium, Na, comes before aluminum, Al, as we move across period 3, of the periodic table, the inter nuclear distance between atoms of in NaCl is larger than the internuclear distances between the atoms of AlCl₃, as well as the presence of more chlorine atoms in AlCl₃ than in NaCl, the lattice energy of NaCl is smaller than the lattice energy of AlCl₃.

Explanation:

The problem basically wants you to find a way to convert between the number of atoms present in the sample and the number of moles they are equivalent to.

To convert between atoms and moles we use something called Avogadro's constant, which basically acts as the definition of a mole.

More specifically, in order to have one mole of an element you need 6.022⋅1023 atoms of that element. You can thus use this number as a conversion factor to take you from atoms to moles or vice versa.

In your case, you will have

The periods go on a periodic table, left to right. The periodic table is the systematic arrangement of elements in row and column.

The chemical elements are arranged in rows and columns in the periodic table, sometimes referred to as the periodic table of the elements. It is often used in physics, chemistry, and other disciplines, and is frequently regarded as a symbol of chemistry.

Because of the orderly arrangement of the elements, it is known as the periodic table. Periods refers to the horizontal rows, and Groups to the vertical columns.

The most significant role of hydrogen in the human body is to maintain your level of hydration, making it the most significant element on the periodic table.

All known elements are grouped together in the periodic table of elements into groups with related characteristics. It becomes a crucial tool for chemists, nanotechnologies, and other scientists as a result. You can forecast how chemicals will behave if you learn to utilize and comprehend the periodic table.

Thus, The periods go on a periodic table, left to right.

because the ammonia is left unclosed

The smell of ammonia has been spread from a corner to entire room by the process of diffusion. Thus, option B is correct.

Ammonia has been the liquid compound with the formula [tex]\rm NH_4[/tex]. It has a pungent smell. Ammonia has been used in several synthesis reactions, and in various industrial processes.

The diffusion has been the process of transfer of molecules from higher concentration to lower concentration. The smell of ammonia has been spread in the entire laboratory from a corner.

The ammonia molecules in the bottle are at higher concentration while there has been lower concentration of ammonia in the environment. With the process of diffusion there has been the transfer of ammonia molecules in the environment.

Thus, diffusion has been responsible for spreading the smell of ammonia in the laboratory from a corner. Thus, option B is correct.

Explanation:

First of all we will understand what is law of conservation of mass.

Law of conservation of mass:

This law stated that, mass can neither be created nor destroyed in a chemical equation.

This law was given by French chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

For example:

In given photosynthesis reaction:

6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂

there are six number of carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of chemical equation so this reaction followed the law of conservation of mass because mases are same on both side.

In given chemical reaction:

AB    + CD      →      X

50 g +  100 g    =  150 g

Thus option c is correct.

Answer:

Li2S> Na2S> K2S> CsS

Explanation:

The lattice energy of ionic species depends on the relative sizes of ions in the ionic compounds. As the size of ions increases, the lattice energy decreases and vice versa.

When the size of the anions are the same, the lattice energy now depends on the relative sizes of the cations. Therefore, since all the compounds are sulphides and the order of magnitude of ionic sizes is: Li^+ < Na^+ < K^+ < Cs^+.

Therefore, the order of decrease in lattice energy is; Li2S> Na2S> K2S> CsS
