In the given reaction, the limiting reactant is C₆H₆ (benzene).
To determine the limiting reactant as well as calculate the mass of HCl produced, compare the moles of each reactant.
The number of moles for each reactant:
Molar mass of Cl₂ = 35.5 g/mol + 35.5 g/mol = 71 g/mol
Moles of Cl₂ = mass of Cl₂ / molar mass of Cl₂
= 45 g / 71 g/mol
= 0.634 moles of Cl₂
Molar mass of C₆H₆ (benzene) = 12 g/mol + 6(1 g/mol) = 78 g/mol
Moles of C₆H₆ = mass of C₆H₆ / molar mass of C₆H₆
= 45 g / 78 g/mol = 0.577 moles of C₆H₆
Determine the stoichiometry between Cl₂ and HCl:
Cl₂ + C₆H₆ → C₆H₅Cl + HCl
Here, we can see that 1 mole of Cl₂ produces 1 mole of HCl.
Thus, the limiting reactant is C₆H₆ (benzene).
Calculate the mass of HCl produced:
Molar mass of HCl = 1 g/mol + 35.5 g/mol = 36.5 g/mol
Moles of HCl produced = moles of C₆H₆ = 0.577 moles
Mass of HCl produced = moles of HCl produced × molar mass of HCl
Mass of HCl produced = 0.577 moles × 36.5 g/mol
≈ 21.04 g
Therefore, approximately 21.04 grams of HCl will be produced.

Answers
Based on the potential energy diagram and the potential energies of reactant and product the synthesis and double replacement reactions are endothermic. The single replacement reaction is exothermic and the ΔH is negative.
What are the differences between endothermic and exothermic reactions ?Chemical processes referred to as endothermic reactions occur when the reactants take in heat energy from their environment to create products. The reaction absorbs energy from its surroundings. The energy that manifests as heat. Examples include cooking, evaporation, gas molecules, melting of ice, and photosynthesis.
An exothermic reaction is one in which energy is given off as heat or light. The mechanism releases energy into its surroundings. Energy can be emitted as sound, light, heat, or electricity. Examples include rusting iron, settling, chemical bonds, explosions, and nuclear fission.
How the potential energy diagram is used to identify if the reaction is endothermic or exothermic?
A potential energy diagram, also known as a reaction progress curve, is a visual representation of the energy changes that take place during a chemical reaction. A diagram of potential energy illustrates how a system's potential energy changes as reactants are changed into products. Note that an exothermic reaction results in a negative enthalpy change while an endothermic reaction exhibits a positive enthalpy change. The diagrams of potential energy show this. When the system absorbs energy from its environment, its overall potential energy rises for the endothermic reaction. As the system undergoes the exothermic process, the system's overall potential energy declines.

How many milliliters of 0.500 M HBr would be required to react with 40.0 mL of 0.300 M Ca(OH)2?
Answers
Answer:
48dm³
Explanation:
Given reaction:
Ca(OH)₂ + 2HBr → CaBr₂ + 2H₂O
Parameters:
Concentration of HBr = 0.5M
Volume of Ca(OH)₂ = 40mL
Concentration of Ca(OH)₂ = 0.3M
Solution:
To solve this problem, we are going to use the mole concept. We solve from the known specie to the unknown.
We first find the number of moles of the known specie which is the Ca(OH)₂ ;
number of moles = concentration x volume
number of moles = 0.3 x 40 x 10⁻³ = 0.012moles
From the reaction equation;
1 mole of Ca(OH)₂ requires 2 moles HBr
0.012 moles of Ca(OH)₂ will require 0.012 x 2 = 0.024moles of HBr
Now,
To find the volume of HBr;
Volume = \(\frac{number of moles }{concentration}\)
Volume = \(\frac{0.024}{0.5}\) = 0.048dm³
In mL;
Volume 0.048 x 1000 = 48dm³

Answers
Answer:

Explanation:
In order to solve this problem, we must apply Graham's law of diffusion in gases. Graham's law states that the rate of diffusion of a gas is inversely proportional to the square root of its vapour density. For two gases we can write;
R1/R2=√d2/d1
Where;
R1= rate of diffusion of hydrogen
R2= rate diffusion of unknown gas
d1= vapour density of hydrogen
d2= vapour density of the unknown gas
Volume of hydrogen gas = 360cm^3
Time taken for hydrogen gas to diffuse= 1 hour =3600 secs
R1 = 360 cm^3/3600 secs = 0.1 cm^3 s-1
Vapour density of unknown gas = 25
Vapour density of hydrogen = 1
Substituting values,
0.1/R2 = √25/1
0.1/R2 = 5/1
5R2 = 0.1 × 1
R2 = 0.1/5
R2= 0.02 cm^3s-1
Volume of unknown gas = 600cm^3
Time taken for unknown gas to diffuse= volume of unknown gas/ rate of diffusion of unknown gas
Time taken for unknown gas to diffuse= 600/0.02
Time= 30,000 seconds or 8.33 hours

Which ion could bond with a calcium ion Which ion could bond with a calcium ion (Ca2+) to form a neutral ionic compound?
A. Cl-
B. NO3-
C. Mg2+
D. S2-(Ca2+)
Answers
The ion that could bond with a calcium ion (Ca2+) to form a neutral ionic compound is option A. Cl-.
This is because the calcium ion has a +2 charge, and the chloride ion (Cl-) has a -1 charge. When these two ions bond together, they form the compound CaCl2, which has a net charge of zero and is therefore neutral.
In order for an ionic compound to be neutral, the charges of the ions must cancel each other out. Therefore, the calcium ion needs to bond with an ion that has a -2 charge in order to form a neutral compound. The chloride ion is the only ion listed that has a -1 charge, and therefore it is the only one that can bond with the calcium ion to form a neutral compound.
So the correct answer is option A. Cl-.

Answer: the pressure exerted by this sample of gas is 2.69 atm
Explanation:
The question requires us to calculate the pressure of a xenon gas, given that there are 0.400 moles of gas in a 3.18 L container at 260.0K.
We can apply the equation for ideal gases to solve this problem:
\(PV=nRT\)where P is the pressure of the gas, V is the volume of the gas, n is the number of moles of gas, T is the temperature and R is the constant of gases.
Since the question requires us to calculate the pressure in units of atmospheres (atm) and the volume of gas was given in litres, we can use the value of R as 0.082057 L.atm/K.mol.
First, let's rearrange the equation for ideal gases in order to calculate the pressure:
\(PV=nRT\rightarrow P=\frac{nRT}{V}\)Next, applying the values given by the question, we'll have:
\(\begin{gathered} P=\frac{(0.400mol)\times(0.082057L.atm/K.mol)\times(260.0K)}{(3.18L)} \\ \\ P=2.69atm \end{gathered}\)Therefore, the pressure exerted by this sample of gas is 2.69 atm.

Based on the law of conservation of mass, when 216 grams of N₂O5 completely decomposes, 184 grams of NO₂ will be produced and 32 grams of O₂.
What is the mass of the products that will be obtained?The mass of the products that will be obtained is calculated as follows:
The number of moles of N₂O5 in 216 grams:
216 g N₂O5 x (1 mol N₂O5/108 g N₂O5) = 2 moles N₂O5
From the balanced equation, 2 moles of N₂O5 will produce 4 moles of NO₂.
Therefore, the mass of NO₂ produced is as follows:

Answers
According to the research, the correct answer is Option 2. If the cell were only permeable to potassium ions there would be a slight change in membrane potential to a more negative value as potassium exits the cell.
What is resting membrane potential?It refers to the potential difference on either side of the membrane of a resting cell, that is, already repolarized where the channels are much more permeable to potassium than to sodium.
In this sense, it is determined by the ion concentration and membrane permeability where the inside of the cell has a more negative charge (potassium ions) relative to the outside (sodium ions).
Therefore, we can conclude that resting membrane potential causes the cell membrane inside to become negative because it has sodium ions towards the outside of the cell and potassium ions towards the inside, thus the correct answer is Option 2.
