Decide which molecules in the simulation will represent the substances from the actual reaction. Include a strategy to deal with the difference in structure between the actual reaction N2 + 3H2 ⇌ 2NH3 and the simulated reaction. Not all molecules need to be used.

        The nitrogen cycle is a repeating cycle of processes during which nitrogen moves through both living and non-living things: the atmosphere, soil, water, plants, animals and bacteria. In order to move through the different parts of the cycle, nitrogen must change forms. The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere, terrestrial, and marine ecosystems. Important processes in the nitrogen cycle include fixation, ammonification, nitrification, and denitrification.

Electromagnetic forces occur between electrons and protons while nuclear forces occur between neutrons and protons in the nucleus.

Electromagnetic forces are the forces that are responsible for the attraction between electrons and protons. The electrons in shells repel each other.

The existence of electromagnetic forces explain why positively charged protons repel each other in the nucleus and neutrons are needed to buffer this effect.

The electromagnetic force has a short range. The strong nuclear force applies to the nucleus and focuses on the neutron - proton ratio.

An atom is unstable if it has too many protons because their repulsive force will exceed the nuclear force that keeps them together. Nuclear force is stronger for lighter nuclei than heavier ones.

The guy above is correct. Gold is a pure substance.

Answer:

aluminum and silicon and the electronegative character of the oxygen.

Explanation:

.

The electronegative character of alumina and silica and the electropositive character of oxygen causes the stationary phase to be very polar.

Electronegativity is defined as the tendency for an atom of a given chemical element to attract shared electrons or electron density when forming a chemical bond.

Non metals are usually an electronegative elements.

Electro positivity is defined as the tendency for an element to lose the electron to form a positive ions.

It is also known as metallic character. Metals are usually an electropositive elements.

Thus, the electronegative character of alumina and silica and the electropositive character of oxygen causes the stationary phase to be very polar.

Magnesium and Chlorine have a great difference in there electronegativies. Due to this, they will form an ionic bond. Magnesium has 2 valence electrons and chlorine has 7. Therefore, two magnesium atoms will give one electron to one chorine atom, making the chlorine atom stable.

The bonding activity of magnesium (mg) and chlorine (Cl) will lead to ionic bonding.

It should be noted that Magnesium and Chlorine have a great difference in their electronegative and this will lead to the formation of an ionic bond.

Magnesium has 2 valence electrons while chlorine has 7 valence electrons. In such a case, the two magnesium atoms will give one electron to one chlorine atom. This is vital for making the chlorine atom stable.

In conclusion, an ionic bond will be formed between them.

Answer:

CuCi2 + H2S ⇒ CuS + 2HCi

Explanation:

In order to balance a chemical equation you need to make sure to have the same number of atoms on each side by multiplying on both sides.

CuCi2 + H2S = CuS + HCi

Cu = 1

Ci = 2

H = 2

S = 1

Product

Cu = 1

S = 1

H = 1 × 2 = 2

Ci = 1 × 2 = 2

Since all elements have a balanced amount of atoms, the equation is now balanced.

CuCi2 + H2S ⇒ CuS + 2HCi

Hope this helps.

A chemical equation is said to be balanced if the quantity of each type of atom in the reaction is the same on both the reactant and product sides. In a balanced chemical equation, the mass and the charge are both equal. Here the balanced equation is CuCl₂ + H₂S → CuS + 2HCl.

A balanced chemical equation, in which the masses of the reactants and products are equal, contains the same amount of atoms of each element on both sides of the equation. In other words, both sides of the reaction have an equal balance of mass and charge.

The chemical equation is said to be balanced if there are no inequalities. Here the balanced equation is:

CuCl₂ + H₂S → CuS + 2HCl

Answer:

0.0111mol/L

Explanation:

M = n/V

We don't know n, but we know that n =mass/Molar mass, so:

n = 8.77g/166.0028 g/mol

n = 0.0528304342mol

M = n/V

M = 0.0528304342mol/ 4.75L

M = 0.111221967mol/L

Round to three sig figs if necessary: 0.0111mol/L

The molarity of the solution is 0.010M.

Molarity:

Molar concentration is a measure of the concentration of a chemical species, in particular of a solute in a solution, in terms of amount of substance per unit volume of solution.

Given:

Mass=8.77g

Volume= 4.75 L

To find:

Molarity=?

Firstly we need to calculate the number of moles.

Molar mass of KI=  166 g/mol

Given mass= 8.77 g

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}} \\\\\text{Number of moles}=\frac{8.77}{166}= 0.05 \text{mol}[/tex]

Now, substituting the values in molarity formula which is given as:

[tex]\text{Molarity}=\frac{n}{V} \\\\\text{Molarity}=\frac{0.05}{4.75} =0.010M[/tex]

Therefore, the molarity of the solution is 0.010M.

Answer:

3.78 gm O2

Explanation:

In the reaction represented by the equation 2Al2O3 → 4A1 + 302, calculate the theoretical amount in grams of oxygen, O2 produced if 11.84 grams Al2O3 decomposes?

for every 2 moles of Al2O3, 3 mole of 02 are produced

molecular weight of Al2O3 =(2X27) + (3X32) =54+96= 150

11.84 gm Al2O3 = 11.84/150 moles =0.0789 moles

This will produce 3/2 X 0.0789 moles of O2 = 0.118 moles O2

mol wt of O2 is 32

0.118 moles weighs 0.118X32 = 3.78 gm O2

Chloride is described as an extended structure because its atoms are arranged following an endless repeating pattern and are of distinct ratio

Crystals and polymers mostly form extended structures as seen in the formation of sodium chloride whereby the ions in the compound are arranged following a repeating pattern. ( i.e. has a giant ionic structure ).

Chloride is a considered an extended structure because in sodium chloride it forms an unending repeated pattern of ions which makes it a perfect example of an extended structure.

Hence we can conclude that Chloride can be described as an extended structure because its atoms are arranged following a repeating pattern and are of distinct ratio.

Crystal of Strontium chloride is described as an extended structure because it is arranged in a repeating pattern.

Crystals form extended structures means a group of atoms or molecules in a distinct ratio that are present in a repeating pattern. Crystals are made up of atoms of one element that grouped together or can be made up of molecules grouped together.

Due to repeating pattern and constant ratio of strontium chloride then it is considered as repeating structure so we can conclude that Crystal of Strontium chloride is considered as an extended structure due to its arrangement in a repeating pattern.
