Answer:

3.702×10^24 atoms of Oxygen.

Total, 6.15 moles of oxygen atoms in 98.4g of oxygen gas (O₂), which is equivalent to 6.15 × 6.022 × 10²³ (Avogadro's number) oxygen atoms.

Oxygen gas (O₂) is indeed diatomic, meaning it exists as a molecule with two oxygen atoms bonded together.

To calculate the number of oxygen atoms in 98.4g of oxygen gas (O₂), we need to use the molar mass of oxygen and the given mass.

The molar mass of oxygen (O₂) will be 32.00 g/mol.

Number of moles of oxygen gas = Mass (g) / Molar mass (g/mol)

Number of moles of oxygen gas = 98.4 g / 32.00 g/mol

≈ 3.075 moles

Since each molecule of oxygen gas (O₂) contains two oxygen atoms, the number of oxygen atoms will be twice the number of moles of oxygen gas.

Number of oxygen atoms = 2 × Number of moles of oxygen gas

Number of oxygen atoms ≈ 2 × 3.075 moles

≈ 6.15 moles

Therefore, there are approximately 6.15 moles of oxygen atoms in 98.4g of oxygen gas (O₂), which is equivalent to 6.15 × 6.022 × 10²³ (Avogadro's number) oxygen atoms.

Answer:

A . The work done stretching a spring is transformed into stored energy in the spring

Explanation:

The work done stretching a spring is transformed into stored energy in the spring is clear indication of the law of conservation of energy.

The law of conservation of energy states that "energy is neither created nor destroyed but transformed from one form to another".

This is an energy transformation process.

Answer:

C. number of particles

Explanation:

Entropy is the measure of disorderliness of a system. Remember that when you dissolve salt in water, you increase the number of particles in the solution. The greater the number of particles in solution, the greater the entropy of the  solution system.

Hence dissolution of a salt in water increases the entropy by increasing the number of particles in solution leading to the inequality; Ssolution > Swater + Ssalt.

A mole is 6.022 x 1023 objects of any kind - atoms, electrons, molecules, cars, people, etc... . It is known as Avogadro's number after the scientist who discovered ... Blah blah I think you get it.  

Explanation:

All the elements in one group have the same number of valence electrons. The valence electrons are those on the energy level the most distant from the nucleus. These valence electrons are those involved in bonding with other atoms to form compounds.

In the periodic table elements in the same group posses similar physical and chemical property and this is due to the similarity in the number of valence electrons found in their  valence shells.

While in the periodic table as we move down a group the atomic number of the elements will continue to increase because elements in the same group are located in different periods as well.

Hence we can conclude that the difference in the elements located in a group is that they have different atomic numbers while the similarities is that the posses the same number of valence electrons.

Less soil erosion

Explanation:

Due to the low amount of rainfall in this region, it is easier to say that the region compared to other ecoregion will suffer less soil erosion.

Erosion is usually the washing away of the top layer of the soil. Rainfall is one of the most important element that causes erosion. Surface runoff for an extended period of time can remove the topmost layer of the earth on which plant can grow. This starves the soil of its rich nutrients and minerals.

Answer:

2, stronger hydrogen bonding

Explanation:

[tex]\rm H_2O[/tex] has higher boiling point than [tex]\rm H_2S[/tex], as there has been stronger hydrogen bonding in [tex]\rm H_2O[/tex]. Thus, option 2 is correct.

The boiling point has been the temperature at which the liquid has been converted to the gaseous form. The boiling point has been based on the intemolecular attractions between the atoms.

Based on the intermolecular interactions, the compound with higher intermolecular force required more energy to break the bond and change the state, and thus have high boiling point.

The hydrogen sulfide and water has hydrogen bonding. The hydrogen bonding has been based on the electronegativity of the atom involved.  The more electronegative atom, stronger will be hydrogen bonding and thereby higher boiling point.

In [tex]\rm H_2S[/tex] and [tex]\rm H_2O[/tex], the oxygen has been more electronegative than sulfur and thus results in stronger hydrogen bonding.

Thus, [tex]\rm H_2O[/tex] has higher boiling point than [tex]\rm H_2S[/tex], as there has been stronger hydrogen bonding in [tex]\rm H_2O[/tex]. Thus, option 2 is correct.

Answer:

At least four glucose residues separate α‑1,6 linkages.

The number of sites for enzyme action on a glycogen molecule is increased through α‑1,6 linkages.

The reaction that forms α-1,6 linkages is catalyzed by a branching enzyme.

Explanation:

Glycogen is a polymer of glucose and is the primary carbohydrate storage form in animals. The polymer is composed of glucose units linked in alpha(1-4) straight chains and alpha(1-6) branches which occur on average every 8-12 straight chain glucose residues. It has a reducing and non-reducing end. The end of the molecule containing a free carbon number one on glucose is called a reducing end. The other ends are all called non-reducing ends.

During the breakdown of glycogen, glucose units are removed one at a time from the non-reducing end until a point about four glucose residues away from a branch which will require a debranching enzyme to act for further breakdown to occur. Since many such branches occur in a glycogen molecule, it makes it possible for breakdown of glycogen to occur at many points speedily.

Glycogen branching enzyme is required to make alpha (1-6) glycosidic bonds. It transfers 6 to 7 glucose units from the non-reducing end of a straight chain glycogen molecule to an interior position of the same or another glycogen molecule forming alpha (1-6) bonds.

Answer:

Work done, W = 900 joules

Explanation:

It is given that,

Force acting on the man, F = 75 N

Distance, d = 12 m

We need to find the work done by the man on the box. Let it is given by W. The work done of an object is equal to the product of force and distance. Mathematically, it can be calculated as :

W = F × d

W=75\ N\times 12\ mW=75 N×12 m

W = 900 joules

So, the work done by the man on the box is 900 joules. Hence, this is the required solution.

Answer: Ionic

Explanation:

Answer:

See below!

Explanation:

An acid (A) will have acid in the name.  It will also have a hydrogen bonded to an electronegative compound.  A molecular compound (M) will have nonmetals and/or hydrogen.  An ionic compound (I) will have nonmetals and first and second column metals.  It could also include charged compounds.  A transition metal (TM) will have a transition metal in the compound.

The formulas for TM and I are made by balancing the charges of the atoms to equal zero.  The formulas for M can be found from the name itself.  The formulas for A have to be memorized.

TM  ==>  copper (II) oxide  ==>  CuO

A  ==>  hydrosulfuric acid  ==>  H₂S

TM  ==>  iron (III) fluoride  ==>  FeF₃

TM  ==>  lead (II) chlorate  ==>  PbCl₂

A  ==>  hydrochloric acid  ==> HCl

M  ==> dihydrogen monoxide  ==>  H₂O

A  ==>  sulfurous acid  ==>  H₂SO₃

I  ==>  potassium oxide  ==>  KO

I ==>  ammonium hydroxide  ==>  NH₄OH

M  ==> nitrogen trioxide  ==>  NO₃

I  ==>  aluminum phosphate  ==>  AlPO₄

To name ionic (I) compounds, simply put the name of the metal with the nonmetal.  But, for the nonmetal change, the ending to "-ide".  To name acids (A), say hydro- with the atom/compound it is attached to and end with acid.

I  ==>  MgSO₄  ==>  magnesium sulfate

I  ==>  HgS  ==>  mercury sulfide

I  ==>  Na₂S  ==>  sodium sulfide

A  ==>  HF  ==>  hydrofluoric acid

I  ==>  KCN  ==>  potassium cyanide
