Explanation:

Equation:

[tex]{ \rm{2Al_{(s) } + 3Cl _{2(g)} \dashrightarrow \: 2AlCl _{3(s)}}}[/tex]

Water has three states of matter namely gas, solid or ice form and liquid. Molecules in solid state are not able to move since they are tightly packed.

Molecules can move in liquid state and they moves easily in gaseous state.

Every substance have three states, that are gas, liquid and solid. In solid state, molecules are tightly packed and are unable to move apart. In liquid state, molecules have some space to move and motion of liquid is easy.

The movement of molecules in a substance depends on the space allotted for them or called the volume. More volume between molecules, easy to move apart.

Gaseous state is composed of molecules located far apart from each other and they diffuse easily. Therefore, motion in three states of water is different and moves faster in gaseous state.

The formula and names of the compounds are:

1. Formula of compound => MoF₃

Name of compound => Molybdenum trifluoride

2. Formula of compound => MoF₄

Name of compound => Molybdenum tetrafluoride

3. Formula of compound => MoF₅

Name of compound => Molybdenum pentafluoride  

4. Formula of compound => MoF₆

Name of compound => Molybdenum hexafluoride  

1. Determination of the name and formula of the molybdenum fluoride having 63.0% of molybdenum.

Molybdenum (Mo) = 63.0%

Fluorine (F) = 100 – 63 = 37%

Mo = 63.0%

F = 37%

Divide by their molar mass

Mo = 63.0 / 96 = 0.656

F = 37 / 19 = 1.947

Divide by the smallest

Mo = 0.656 / 0.656 = 1

F = 1.947 / 0.656 = 3

Therefore,

Formula of compound => MoF₃

Name of compound => Molybdenum trifluoride

2. Determination of the name and formula of the molybdenum fluoride having 56.0% of molybdenum.

Molybdenum (Mo) = 56.0%,

Fluorine (F) = 100 – 56 = 44%

Mo = 56%

F = 44%

Divide by their molar mass

Mo = 56 / 96 = 0.583

F = 44 / 19 = 2.316

Divide by the smallest

Mo = 0.583 / 0.583 = 1

F = 2.316 / 0.583 = 4

Therefore,

Formula of compound => MoF₄

Name of compound => Molybdenum tetrafluoride

3. Determination of the name and formula of the molybdenum fluoride having 50.0% of molybdenum.

Molybdenum (Mo) = 50.0%,

Fluorine (F) = 100 – 50 = 50%

Mo = 50%

F = 50%

Divide by their molar mass

Mo = 50 / 96 = 0.520

F = 50 / 19 = 2.632

Divide by the smallest

Mo = 0.520 / 0.520 = 1

F = 2.632 / 0.520 = 5

Therefore,

Formula of compound => MoF₅

Name of compound => Molybdenum pentafluoride  

4. Determination of the name and formula of the molybdenum fluoride having 46.0% of molybdenum.

Molybdenum (Mo) = 46.0%,

Fluorine (F) = 100 – 46 = 54%

Mo = 46%

F = 54%

Divide by their molar mass

Mo = 46 / 96 = 0.479

F = 54 / 19 = 2.842

Divide by the smallest

Mo = 0.479 / 0.479 = 1

F = 2.842 / 0.479 = 6

Therefore,

Formula of compound => MoF₆

Name of compound => Molybdenum hexafluoride

Answer:

Congestive heart failure

Explanation:

Congestive heart failure happens when your heart gets too weak to pump blood from the lungs out to the body. Pressure builds up in the heart which puts pressure on the blood vessels of the lungs. This will lead to leakage of the vessels and the fluids build up in the air sacs of the lungs. This condition is called pulmonary edema.

Pulmonary edema occurs when fluid builds up in the lungs making it hard to breathe. It may start out as running out of breath easily but if left untreated (both conditions) symptoms get worse over time.

The (15-35-15) number on a bag of fertilizer is calculated by an outdated method.  Using the knowledge of the old methods, the number of moles of phosphorus found in 10.0 grams of phosphorus is 0.05 mole.

The (15-35-15) number on the bag of fertilizer is used for:

Thus, in a 100-gram bag of fertilizer, there are 35 grams of phosphorus pentoxide P₂O₅.

∴

To determine the number of moles of 10 grams of phosphorus pentoxide in (15-35-15) bag of fertilizer, we have:

[tex]\mathbf{=10 \times \dfrac{35}{100} \ grams \ of \ P_2O_5}[/tex]

= 3.5 grams of P₂O₅

Recall that:

[tex]\mathbf{Number of moles = \dfrac{mass}{molar \ mass}}[/tex]

∴

[tex]\mathbf{Number of moles = \dfrac{3.5\ g}{ 142 \ g/mol}}[/tex]

[tex]\mathbf{Number of moles = 0.0246 \ mol}[/tex]

Provided that 1 mole of P₂O₅ harbors 2 moles of phosphorus;

Then;

The number of phosphorus present in 10.0 grams of (15-35-15) fertilizer is:

= 0.0246 moles × 2

= 0.0492 moles

≅ 0.05 moles

Therefore, we can conclude that the number of moles of phosphorus found in 10.0 grams of  (15-35-15) bag of fertilizer is 0.05 moles.

Answer: iron

Explanation: Metals' atoms are closely bonded in a crystal lattice. In metallic bonds, the electron cloud boundaries of atoms touch each other. Many nonmetals occur as diatomic molecules. The electron clouds of these two bonded nonmetal atoms overlap .

Hydrogen atoms are most likely to touch each other without overlapping because of their small size and simple atomic structure.

A hydrogen molecule is a particle of the synthetic component hydrogen. The electrically unbiased molecule contains a solitary emphatically charged proton and a solitary adversely charged electron bound to the core by the Coulomb force. Nuclear hydrogen is around 75% of the baryonic mass of the universe.

Hydrogen exist as diatomic particle, I.e., it can exist by attaching to another hydrogen. You realize that hydrogen has just a single electron in it's furthest and just shell. Yet, to accomplish a steady design, there should be two electrons in this shell. So two hydrogen molecules share their electrons by holding.

Explanation:

The angle between the following two hybrid orbitals on the same atom is sp and sp hybrid orbitals: 180°, sp and sp hybrid orbitals: 120° and sp and sp2 hybrid orbitals: 109.5°

Hybrid orbitals are defined as the outcome of a model that generates a new set of orbitals by combining atomic orbitals on a single atom.

It can also be defined as a form of atomic orbital that emerges when two or more atomic orbitals of an isolated atom mix.

It can be defined as the forming new atomic orbitals by combining two or more common atomic orbitals.

The process which forms hybrid orbitals are known as hybridization.

There are mainly five types of hybridization.

Thus, the angle between the following two hybrid orbitals on the same atom is sp and sp hybrid orbitals: 180°, sp and sp hybrid orbitals: 120° and sp and sp2 hybrid orbitals: 109.5°
