Bromine monochloride is synthesized using the reaction Br2(g)+Cl2(g)↽−−⇀2BrCl(g)p=1.1×10−4 at 150 K A 201.0 L flask initially contains 0.902 kg of Br2 and 1.066 kg of Cl2. Calculate the mass of BrCl , in grams, that is present in the reaction mixture at equilibrium. Assume ideal gas behavior.
The mass of BrCl that is present in the reaction mixture at equilibrium is 0.519 grams
What is a mass of BrCl?Generally, To calculate the mass of BrCl present at equilibrium, we need to use the equilibrium constant expression (Kp) for the reaction:
Kp = [BrCl]^2 / [Br2] [Cl2]
where [BrCl], [Br2], and [Cl2] are the concentrations of the respective gases at equilibrium.
Since we know the initial amounts of Br2 and Cl2, and the volume of the flask, we can calculate the initial concentrations of each gas.
[Br2]_initial = 0.902 kg / (201.0 L * 0.08206 Latm/molK * 150 K)
= 0.0014 mol/L [Cl2]_initial
= 1.066 kg / (201.0 L * 0.08206 Latm/molK * 150 K)
= 0.0017 mol/L
We are also given the value of Kp, so we can substitute the initial concentrations into the Kp expression and solve for [BrCl].
Kp = [BrCl]^2 / 0.0014 mol/L * 0.0017 mol/L
= (1.1×10^-4)
[BrCl] = √(Kp * [Br2]_initial * [Cl2]_initial)
=√(1.1×10^-4 * 0.0014 mol/L * 0.0017 mol/L)
= 1.61802349*10^{-5} mol/L
To convert molarity to mass, we need to multiply the molarity by the molar mass of BrCl.
The molar mass of BrCl is
(2 * 79.904 g/mol) = 159.808 g/mol.
mass of BrCl = [BrCl] * V * M
=1.61802349*10^{-5}mol/L * 201.0 L * 159.808 g/mol
= 0.519 grams

To inflate an airbag to 73.1 L at s.t.p., we need to know the moles of gas produced by the decomposition of sodium azide. We can use the Ideal Gas Law, PV = nRT, to calculate this.
We know that P = 1 atm (s.t.p.), V = 73.1 L, R = 0.08206 Latm/molK, and T = 273 K (0 °C).
Rearrange the Ideal Gas Law to n = PV/RTn = (1 atm * 73.1 L) / (0.08206 Latm/molK * 273 K)
n = 0.26 moles of N2 gas
Since 2 moles of N2 are produced per mole of NaN3, we can divide the number of moles of N2 by 2 to find the number of moles of NaN3.
n(NaN3) = n(N2) / 2n(NaN3) = 0.26 moles / 2 = 0.13 moles. To find the mass, we multiply the number of moles by the molar mass of NaN3.
mass(NaN3) = n(NaN3) * molar mass(NaN3)
mass(NaN3) = 0.13 moles * 65.01 g/mol ≈ 8.45 g

0.968 × 0.0665 = n × 0.0821 × 293
Divide both sides by (0.0821 × 293)
n = (0.968 × 0.0665) / (0.0821 × 293)
n = 0.003 mole

X(s) + 4HCl(aq) → XCl₄(aq) + 2H₂(g)
From the balanced equation above,
2 moles of H₂ were obtained from 1 mole of X
Therefore,
0.003 moles of H₂ will obtained from = 0.003 / 2 = 0.0015 mole of X
Finally, we shall determine the identity of the metal by obtaining it's molar mass. Details below:
Mole of metal X = 0.0015 moleMass of metal X = 0.160 gMolar mass of metal X =?Molar mass = mass / mole
Molar mass of X = 0.160 / 0.0015

Write the net ionic equation for the following molecular equation.HBr is a strong electrolyte. HF is a weak electrolyte.KF(aq) + HBr(aq) → KBr(aq) + HF (aq)(Use the lowest possible coefficients. Be sure to specify states such as (aq) or (s). If a box is not needed, leave it blank.)
The chemical equation used for a chemical reaction involving ionic species is called the complete ionic equation.
What is a net ionic equation?The chemical equation known as the net ionic equation only displays the substances that are directly involved in the chemical process.By dissolving all soluble ionic chemicals (those denoted with a (aq)) into their corresponding ions, the ionic equation can be written. To demonstrate that an ion is present in solution, it should be displayed with its charge and a (aq). To display the quantity of each ion present, use coefficients.A complete ionic equation also contains the spectator ions, whereas a net ionic equation just displays the chemical species that are involved in a reaction.A chemical equation for a process known as the net ionic equation only includes the species that are really involved in the reaction. In double displacement reactions, redox reactions, and acid-base neutralisation processes, the net ionic equation is frequently employed.The corresponding ionic equation is:
{eq}K^{+}(aq) + CH_{3}COO^{-}(aq) + H^{+}(aq) + Br^{-}(aq) ⇒K^{+}(aq) + Br^{-}(aq)

A 50 mL solution of strong acid of pH = 1 is mixed with a 50 mL solution of strong acid of pH = 2. The pH of the mixture will be :
(log105.5=0.74AB1.26C1.76D
The pH of the mixture will be approximately 1.04 (Option A).
The pH of an acid solution is defined as the negative logarithm of the hydrogen ion concentration. Since both solutions are strong acids, they will have a high hydrogen ion concentration and a low pH. The pH of the first solution is 1, and the pH of the second solution is 2, which means the first solution has a hydrogen ion concentration of 10^-1 M and the second solution has a hydrogen ion concentration of 10^-2 M.
When the solutions are mixed, the final hydrogen ion concentration will be the sum of the initial concentrations.final [H+] = [H+]1 + [H+]2 = 10^-1 M + 10^-2 M = 1.1*10^-1 M
So, the pH of the mixture is:
pH = -log(11 x 10^-2) = -log(11) + log(10^-2) = 1.04. Therefore, the answer is A (1.04).

Based on the Tonicity in Elodea Cells lab, a hypotonic environment causes a cell to swell or burst because
-the water in the solution moves into the plant cell.
-the solutes in the solution have a lower concentration than the solute concentration inside the plant cell.
-the water is moving down its concentration gradient from high to low.
-The water moved across the selectively permeable membrane down its concentration gradient from an area of high water concentration to an area of low water concentration. There were fewer solutes in the solution and more solutes in the cell, which is why the water moved into the cell.
A hypotonic environment causes a cell to swell or burst because the water is moving down its concentration gradient from high to low.
What is hypotonic environment?
A hypotonic environment is an environment where the concentration of solutes outside a cell is lower than the concentration of solutes inside the cell. This can cause water to move into the cell by osmosis, causing the cell to swell and possibly even burst. Hypotonic environments are most commonly found in aquatic environments, but can also be seen in a variety of other settings, such as in a cell culture dish or in a protein crystallization experiment. In the case of aquatic environments, hypotonic solutions are those that have a lower salt concentration than the solution inside the cell, causing the cell to absorb more water than it would in a hypertonic solution.
