Answer:

1.181 × 10²⁴ molecules CO₂

General Formulas and Concepts:

Chemistry - Atomic Structure

Explanation:

Step 1: Define

86.34 g CO₂

Step 2: Identify Conversion

Avogadro's Number

Molar Mass of C - 12.01 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of CO₂ - 12.01 + 2(16.00) = 44.01 g/mol

Step 3: Convert

[tex]86.34 \ g \ CO_2(\frac{1 \ mol \ CO_2}{44.01 \ g \ CO_2} )(\frac{6.022 \cdot 10^{23} \ molecules \ CO_2}{1 \ mol \ CO_2} )[/tex] = 1.18141 × 10²⁴ molecules CO₂

Step 4: Check

We are given 4 sig figs. Follow sig fig rules and round.

1.18141 × 10²⁴ molecules CO₂ ≈ 1.181 × 10²⁴ molecules CO₂

what are the properties of iconic compounds?

Ionic compounds exist in the form of ionic groupings in certain forms called (crystalline forms), and we find in these shapes an organized crystal arrangement of ions so that every ion with a specific charge is attracted to a group of ions with the opposite charge, meaning that one ion is bound by several ionic bonds. At the same time, this explains the presence of ionic compounds usually in the solid state (high density). This situation also explains the high melting and boiling points of these compounds.

One of the most important characteristics of ionic compounds is their inability to conduct electrical conductivity in the solid state due to the ions binding and their inability to move while they become conductive of electricity when they are melted or dissolved in water (ions are free to move in the melt and in the aqueous solution).

And among its most important characteristics:

1- It dissolves in water and does not dissolve with benzene, for example (salt) because water is a polar solvent that can separate ions from each other.

2- It has a high melting point due to the force of electrostatic attraction between the positive and negative ions.

3- Its state is solid under normal conditions, due to the force of the electrostatic attraction between the positive and negative ions.

4- Solid ionic compounds do not conduct electricity, but their solutions with water conduct electricity, because when the compound is solid, the ions are connected to each other, but when the compound is a solution, the ions are free to move and conduct the electromagnetic current.

what are the properties of covalent compounds?

In covalent compounds (unlike ionic compounds), we can talk about independent molecules, as covalent compounds are composed of independent molecules linked together by different bonds (van derval, hydrogen) of varying strength. So there are covalent compounds in all three cases according to the strength of these bonds. There are covalent compounds in a gaseous state (weak bonds between molecules), covalent compounds in a liquid state, and also there are covalent compounds in a solid state (strong bonds between molecules). The same is true for melting and boiling points, so covalent compounds Their boiling and melting points vary according to the quality and strength of the bonds between the molecules.  

As for the electrical conductivity, in the pure state, the covalent compounds are mostly non-conductive because they are not originally charged or because they are electrically neutral in the presence of charges, but the charged ones may have what is known as the electric torque and will come.

Likewise, in their smelters, the molten solid covalent compound (such as molten sugar) is not conductive of electricity. As for the solution, it may be non-conductive as in the case of a sugar solution or be conductive as is the case in a solution of hydrogen chloride (hydrochloric acid) and the reason for conducting or not in the solution is due to The covalent compound ionization (conversion into separate ions by the action of a solvent) or its de-ionization.

Sugar does not ionize when dissolved in water. Rather, its molecules only separate from each other, while hydrogen chloride does ionize to the hydrogen ion and the chlorine ion.

which type of compound is sugar?

The chemical or molecular formula for sucrose is C 12 H 22 O 11, which means that each sugar molecule contains 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms. A type of sugar called sucrose is also known as sucrose. It is a sucrase made in many different plants.

The properties of the compounds are the following:

a. The properties of the ionic compounds are they are hard, form crystals, have high melting and boiling point, good insulators.

b. The properties of the covalent compound are they are soft, do not form the crystal, have low melting and boiling point, bad insulators.

c. Sugar is a covalent compound.

Covalent compounds are attracted by covalent bonds. They make bonds by sharing one or more pairs of valence electrons.

These compounds are ions or charged particles. They make bonds when an atom or more atoms lose or gain electrons.

Thus, the properties are a. The properties of the ionic compounds are they are hard, form crystals, have high melting and boiling point, good insulators.

b. The properties of the covalent compound are they are soft, do not form the crystal, have low melting and boiling point, bad insulators.

c. Sugar is a covalent compound.

Answer:

132g/mol

Explanation:

Given compound:

   C₆H₁₂O₆

Molecular mass of the compound.

 This is the sum of the atomic masses of the given elements in the compound;

  C = 12

  H  = 12

  O = 6

Molecular mass = 6(12) + 12(1) + 6(16) = 180g/mol

Answer:

To answer the question, we correctly fill the attached screenshot as follows;

[tex]100.0 g \ H_2 \times \dfrac{1 \ mol \ H_2}{2 \ g \ H_2} \times \dfrac{2 \ mol \ NH_3}{3 \ mol \ H_2} = 33.\bar 3 \ mol \ NH_3[/tex]

The molar mass of N₂ = 28 g/mol

[tex]100.0 g \ N_2 \times \dfrac{1 \ mol \ N_2}{28 \ g \ N_2} \times \dfrac{2 \ mol \ NH_3}{1 \ mol \ N_2} \approx 7.143 \ mol \ NH_3[/tex]

A. Therefore, the excess reactant is hydrogen gas H₂ because it makes the most amount of ammonia, NH₃ (33.[tex]\bar 3[/tex] moles of NH₃)

B. The limiting reactant in nitrogen, N₂, because it is the reactant that makes the least amount of the ammonia, NH₃ (approximately 7.143 mol NH₃)

C. The theoretical yield of ammonia, is the maximum amount of ammonium that can be produced from the reaction between the 100 g of hydrogen gas, H₂, and 100 g of nitrogen gas, N₂ which is given by the amount of ammonia produced by the limiting reactant which is approximately 7.143 mole of NH₃

Answer:

In the human body, potential energy is stored in the bonds between atoms and molecules. Chemical energy is the form of potential energy in which energy is stored in chemical bonds. When those bonds are formed, chemical energy is invested, and when they break, chemical energy is released. Notice that chemical energy, like all energy, is neither created nor destroyed; rather, it is converted from one form to another. When you eat an energy bar before heading out the door for a hike, the honey, nuts, and other foods the bar contains are broken down and rearranged by your body into molecules that your muscle cells convert to kinetic energy.

Radioactive elements

Stable

Explanation:

Radioactive elements that have a longer half-life are more stable than those that a shorter half-life.

Half-life is the time taken for half of a radioactive element to decay by half of its original composition.

Now, if a substance have a long half-life, it is more stable and takes time to break down. For atoms with a short life, they are highly unstable and breaks down readily and easily.

Answer:

b. Their shells

Explanation:

The electronic shell of atoms represents the energy levels in a particular atom.

To understand the way atoms absorb energy, we must know that the wavelength absorbed is commensurate with the energy of the atom. This available energy allows for specific amount of energy to be absorbed.

Therefore, the electronic shell in an atom determines the absorption wavelength of the atom.
