Isomerization reactionIsomerization is the transformation of a molecule into a different isomer, and it can take one of two forms: cis or trans. Protein isomerization was first described in 1968 as a method of dramatically altering protein conformation by disrupting polypeptide secondary structure.
Isomerism is caused by two main factors: Difference in atom linking mode. Difference in the spatial arrangement of atoms or groups. The difference in the mode of atom linking is one of the two main causes of isomerism. Difference in the spatial arrangement of atoms or groups.
Types :The two main types of isomerism are structural or constitutional isomerism, in which the bonds between the atoms differ, and stereoisomerism or spatial isomerism, which occurs when the bonds are similar but the relative positions of the atoms differ.

What is the limiting reactant if 0.5 g Al is reacted with 0.5 g CuCl2?
What is the theoretical yield of copper produced by this reaction?
Taking into account the reaction stoichiometry ,CuCl₂ is the limiting reagent and the theoretical yield of copper produced is 0.2363 grams.
Reaction stoichiometryIn first place, the balanced reaction is:
2 Al + 3 CuCl₂ → 3 Cu + 2 AlCl₃
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
Al: 2 molesCuCl₂: 3 molesCu: 3 molesAlCl₃: 2 molesThe molar mass of the compounds is:
Al: 27 g/moleCuCl₂: 134.44 g/moleCu: 63.54 g/moleAlCl₃: 133.35 g/moleThen, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
Al: 2 moles ×27 g/mole= 54 gramsCuCl₂: 3 moles ×134.44 g/mole= 403.32 gramsCu: 3 moles ×63.54 g/mole= 190.62 gramsAlCl₃: 2 moles ×133.35 g/mole= 266.7 gramsLimiting reagentThe limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.
Limiting reagent in this caseTo determine the limiting reagent, it is possible to use a simple rule of three as follows: if by stoichiometry 54 grams of Al reacts with 403.32 grams of CuCl₂, 0.5 grams of Al reacts with how much mass of CuCl₂?
mass of CuCl₂= (0.5 grams of Al× 403.32 grams of CuCl₂)÷ 54 grams of Al
mass of CuCl₂= 3.734 grams
But 3.734 grams of CuCl₂ are not available, 0.5 grams are available. Since you have less mass than you need to react with 0.5 grams of Al, CuCl₂ will be the limiting reagent.
Definition of theoretical yieldThe theoretical yield is the amount of product acquired through the complete conversion of all reagents in the final product, that is, it is the maximum amount of product that could be formed from the given amounts of reagents.
Theoretical yield of copperConsidering the limiting reagent, the following rule of three can be applied: if by reaction stoichiometry 403.32 grams of CuCl₂ form 190.62 grams of Cu, 0.5 grams of CuCl₂ form how much mass of Cu?
mass of Cu= (0.5 grams of CuCl₂× 190.62 grams of Cu)÷ 403.32 grams of CuCl₂
mass of Cu= 0.2363 grams
Then, the theoretical yield of copper produced is 0.2363 grams.
SummaryIn summary, you obtain:
CuCl₂ is the limiting reagent.the theoretical yield of copper produced is 0.2363 grams.Learn more about theoretical yield:

2. How many grams of copper(II) chloride contain 2.17 grams of Cu²+?
4.63 gram of Cooper(II) chloride contain 2.17 grams of Cu²+
Molar mass of copper(II) chloride = 134.45 g/mol
Molar mass of copper = 63 grams
The average mass of an element's atoms expressed in atomic mass units is known as its atomic mass (amu, also known as daltons, D). The mass of each isotope is multiplied by its abundance to produce the atomic mass, which is a weighted average of all the isotopes of that element.
63 gram of copper is present in 134.45 g/mol of copper(II) chloride
1 gram copper is present in copper(II) chloride = 134.45/63 = 2.13 gram

If the oxide contains 22.24 % O by mass, what is the identity of the metal?
Express your answer as a chemical symbol.
The oxide contains 22.24% O by mass, so the identity of the metal as a chemical symbol is lead (Pb).
What is metal?A substance with high electrical conductivity, luster, and malleability, which readily loses electrons to form positive ions (cations) are called metals.
Mass percentage of oxygen in the oxide, i.e.,
ω(O) divided by 100 ω(O)
=22.24% ÷ 100%.
Mass percentage of oxygen in the oxide, i.e .ω(O) = 0.2224
Now the mass percentage of oxygen in the oxide multiplied by 100 ten we get the mass of oxygen in the oxide. If we take 100 grams of compound:
1) m(O) = ω(O) * 100 g.
Mass of oxygen in the oxide, i.e. m(O) = 0.2224 * 100 g.
Mass of oxygen in the oxide. i.e., m(O) =22.24g
Amount of oxygen, i.e.,
n(O) = mass of oxygen in the oxide ÷ molar mass of oxygen.
n(O) = m(O) ÷ M(O) amount of oxygen
n(O) = 22.24g ÷ 16 g/mol,
amount of oxygen i.e. n(O) = 1.39 mol
Mass of metal in the oxide, i.e., m(M) = 100 g - 22.24 g.
Mass of metal in the oxide i.e., m(M) = 77.76g
Now we to find the molar mass of metal oxide,
Molar mass of the metal :
= mass of metal in the oxide ÷ amount of oxygen(M)
= m(M) ÷ n(M). M(M)
= 77.76 g ÷ 1.39 mol.
Molar mass of the metal will be 5.94 g/mol.
Therefore, The identity of the metal is lead (Pb).

Taking into account the definition of density, the volume of 1.95 kg of alcohol is 2.6083 quarts.
Definition of densityDensity is a quantity that allows us to measure the amount of mass in a certain volume of a substance.
The expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:
density= mass÷ volume
It can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.
Volume in this caseIn this case, you know that:
Density= 0.79 g/mLMass= 1.95 kg= 1950 gReplacing in the definition of density:
0.79 g/mL= 1950 g÷ volume
Solving:
0.79 g/mL ×volume= 1950 g
volume= 1950 g÷ 0.79 g/mL
volume= 2468.35 mL= 2.6083 quarts (being 1 mL= 0.00105669 quarts)

We know that there is [tex]6.022[/tex] × [tex]10^{23}[/tex] atoms in a mole of any substance.
[tex]6.022[/tex] × [tex]10^{23}[/tex] is Avogadro's Constant
[tex]6.022[/tex] × [tex]10^{23}[/tex] × 3 = [tex]1.8066[/tex] × [tex]10^{24}[/tex]
Therefore in 3 moles of ammonia, there are [tex]1.8066[/tex] × [tex]10^{24}[/tex] atoms.
Next, you should determine how many molecules of an element is present in ammonia.
There is 1 Nitrogen molecule and 3 Hydrogen molecules for every mole of ammonia.
Finally, since we know 3 moles of ammonia contains [tex]1.8066[/tex] × [tex]10^{24}[/tex] atoms, we just have to multiply accordingly to get the individual amount of atoms of an element a compound has.
For Nitrogen :

Calculate the density in g/ml of 2.0 L of gasoline that weighs 1.32 kg
Answer: 0.66 g/mL
Explanation: The formula for density is d= m/v where m=mass and v=volume.
The mass was given in the problem, m= 1.32kg
The volume was also given in the problem, v= 2.0L
d= m/v ---> d= 1.32kg/2.0L ---> d=0.66kg/L
The problem calls for the answer to be written in g/mL, so we must convert the units. 1 kg contains 1000g and 1 L contains 1000 mL.
1000g/1000mL = 1 so the units change but the 0.66 does not. Therefore, your answer is 0.66g/mL (Two significant figures because 2.0 only has 2 significant figures).
