Al atom hybridization switches from being sp2 in AlCl3 to being sp3 in AlCl4.
What is hybridization?
Al has three bond pairs of electrons and no lone pairs of electrons in AlCl3. pondering the degree to which carbon atoms have hybridised. Hybridization state theory was first proposed by Linus Pauling in 1931 to explain the structure of molecules like methane (CH4). The steric number is calculated by adding the number of atoms an atom is bound to and the number of lone pairs it has. The atom is sp3 hybridised if the steric number is 4.
The atom is sp2 hybridised if the steric number is 3. Since C2 has three sigma bonds, its hybridization is sp2. Since C3 has two sigma bonds, C2 hybridises with C3.

a tank at is filled with of sulfur tetrafluoride gas and of dinitrogen difluoride gas. you can assume both gases behave as ideal gases under these conditions.
Mole fraction of N2O is 0.330 and mole fraction of SF4 is 0.669; pressure N2O is 39127.053 Pa ; pressure of SF4 is 792126.36 and total pressure is 118253.413 Pa
What is pressure in chemistry?If volume and temperature are held constant, ideal gas equation can be rearranged to show that pressure of a sample of gas is directly proportional to number of moles.
Given, volume of tank is 8 L
Weight of dinitrogen difluoride gas is 5.53 g
weight of Sulphur hexafluoride gas is 17.3 g
Amount of N2O= 5.53/ (14 * 2 + 16)
= 0.1256 mol
amount of SF4 = 17.3 /( 32.1 + 19 *4 )
= 0.254 mol
mole fraction of N2O= 0.1256/( 0.1256 + 0.254)
= 0.330
amount of SF4= 0.254/( 0.1256 + 0.254)
= 0.669
PV = n RT
P of N2O = 0.1256* 8.31 ( 273 + 26.9)/0.008
= 39127.053 Pa
mole of SF4 = 0.254* 8.31 ( 273 + 26.9)/0.008
= 79126.36 Pa
Therefore, total pressure = 39127.053 + 79126.36 = 118253.413 Pa

suppose of zinc bromide is dissolved in of a aqueous solution of potassium carbonate. calculate the final molarity of bromide anion in the solution. you can assume the volume of the solution doesn't change when the zinc bromide is dissolved in it. be sure your answer has the correct number of significant digits.
The final molarity of the zinc cation in the solution is [Zn²⁺] = 4.78x10⁻¹⁰M.
The balanced chemical equation for the above reaction is given as:
ZnBr₂ (aq) + K₂CO₃ (aq) → ZnCO₃ (s) + 2KBr (aq)
The zinc that is added produce the insoluble ZnCO₃ with Ksp = 1.46x10⁻¹⁰:
1.46x10⁻¹⁰ = [Zn²⁺] [CO₃²⁻]
Let's find the moles of ZnBr₂ added = Moles of Zn²⁺ and moles of K₂CO₃ = Moles of CO₃²⁻ we can find the moles of CO₃²⁻ that remains in solution, as follows:
Moles of ZnB₂ (Molar mass: 225.2g/mol) = Moles Zn²⁺:
6.63g ZnBr₂ × (1mol / 225.2g) = 0.02944 moles of Zn²⁺
Moles of K₂CO₃ = Moles of CO₃²⁻:
0.100L × (0.60mol/L) = 0.060 moles CO₃²⁻
Moles CO₃²⁻ in excess: 0.0600moles CO₃²⁻ - 0.02944moles =
0.03056moles CO₃²⁻ / 0.100L = 0.3056M = [CO₃²⁻]
Substituting in Ksp expression:
1.46x10⁻¹⁰ = [Zn²⁺] [0.3056M]
[Zn²⁺] = 4.78x10⁻¹⁰M
Hence, the final molarity of the zinc cation in the solution is [Zn²⁺] = 4.78x10⁻¹⁰M.

Explanation:
To calculate this, we simply add the mass of the salicylic acid and the mass of the copper sulphate.
The addition will yield the following.
Mass of salicylic acid recovered = 0.586g
Mass of copper sulphate recovered = 3.12g
The addition of both is = 0.586g + 3.12g = 3.706g
The percentage composition can be calculated by dividing this by the original mass of the mixture before crystallization and dividing by 100.

Hydrochloric acid in the stomach is a very strong acid compared
to ethanoic acid that is found in citrus fruits. Explain (with
reference to formation of hydronium ions) why hydrochloric acid
has a much lower pH compared to ethanoic acid. You should
support this answer with accompanying ionic equations.
Answer:
Explanation:Hydrochloric acid (HCl) in the stomach is a much stronger acid than ethanoic acid (also known as acetic acid) found in citrus fruits. The strength of an acid is determined by its ability to donate protons (H+ ions) to a solution, and the concentration of H+ ions in a solution determines its pH. A solution with a higher concentration of H+ ions will have a lower pH, while a solution with a lower concentration of H+ ions will have a higher pH.
When hydrochloric acid is dissolved in water, it ionizes to form hydronium ions (H3O+) and chloride ions (Cl-). This process can be represented by the following ionic equation:
HCl + H2O → H3O+ + Cl-
The hydronium ions that are formed in this reaction are responsible for the acidity of the solution. The concentration of hydronium ions in a solution of hydrochloric acid is much higher than the concentration of H+ ions in a solution of ethanoic acid, which means that hydrochloric acid has a much lower pH compared to ethanoic acid.
The ionization of ethanoic acid in water is a similar process, but it results in the formation of fewer H+ ions compared to hydrochloric acid. This is because ethanoic acid is a weaker acid than hydrochloric acid, and it donates fewer protons to the solution. The ionic equation for the ionization of ethanoic acid in water is as follows:
CH3COOH + H2O → CH3COO- + H3O+
As you can see, the ionization of ethanoic acid results in the formation of one H3O+ ion for every molecule of acid that ionizes. In comparison, the ionization of hydrochloric acid results in the formation of one H3O+ ion for every molecule of acid that ionizes, plus an additional H+ ion. This means that the concentration of H+ ions in a solution of hydrochloric acid is much higher than the concentration of H+ ions in a solution of ethanoic acid, which leads to a much lower pH for hydrochloric acid compared to ethanoic acid.
I hope this helps to explain the difference in pH between hydrochloric acid and ethanoic acid. Let me know if you have any other questions.

Select each molecule that would show only a pair of doublets ...
A substance's state of matter — solid, liquid, gas, or plasma — depends on how its molecules move and maintain their volume and shape.
The process of forming a disaccharide molecule and a water molecule with the help of two molecules of glucose is known as a dehydration reaction. This is because a water molecule is liberated from the reacting molecules of glucose.
Collision theory is a theory which describes of predicting the rate at which chemical reactions occurs between atoms and molecules of elements.
So therefore, the factor which will not determines if two molecules will bind according to collision theory is the direction the molecules are facing
Molecules are made up of atoms and these atoms are positive or negative. Here, the protons which have different chemical shifts are chemically non-equivalent and they exist in different environment. Hence, the compound shown is the only pair of doublet with integration ratio 1:1
Therefore, we can say that the molecules are made up of some positive and negative ions called protons and electrons.
