It is not possible to determine the concentration of chlorine in the tank after 20 minutes. It takes approximately 2.96 minutes for the concentration of chlorine in the tank to reach 180 kg/m³.

The concentration of chlorine in a water treatment plant is to be determined as a function of time, as well as its concentration after 20 minutes and the time it takes to reach a concentration of 180 kg.

(a) (i) Using a mass balance equation, let C be the chlorine concentration in the tank and t be time. The mass of chlorine in the tank at any time, M(t), is M(t) = VC where V is the volume of water in the tank, which is initially 100 m3. The rate of change of chlorine concentration in the tank, dC/dt, is given by dC/dt = (1/V) dM/dt. Using the given values of the inlet and outlet rates, the rate at which chlorine enters the tank is dM/dt = 0.4 kg/m3 × 20 m3/min = 8 kg/min. The rate at which chlorine leaves the tank is given by the product of the concentration and the outlet rate. When the tank is initially filled with untreated water, the concentration of chlorine is zero.

Therefore, the rate at which chlorine leaves the tank initially is dM/dt = C × 10 m3/min = 0.This means that the concentration of chlorine in the tank remains zero until chlorine begins to enter the tank. Therefore, for t > 0, the differential equation is dC/dt = 8/(100 − 10t)Solving this differential equation gives C = ln(100 − 10t) + K where K is the constant of integration. The value of K can be found using the initial condition that the concentration of chlorine is zero when t = 0:C = ln(100 − 10t) − 2.3026

(ii) The concentration of chlorine in the tank after 20 minutes is C = ln(100 − 10(20)) − 2.3026= ln(−100) − 2.3026The value of the natural logarithm is undefined for negative numbers. Therefore, it is not possible to determine the concentration of chlorine in the tank after 20 minutes.

(iii) To find the time at which the concentration of chlorine in the tank reaches 180 kg/m3, set C equal to 180 kg/m³ and solve for t:180 = ln(100 − 10t) − 2.3026182.3026 = ln(100 − 10t)10t = 29.6493t = 2.9649 min. Therefore, it takes approximately 2.96 minutes for the concentration of chlorine in the tank to reach 180 kg/m³.

Yes, a precipitate will form if you mix together 100 mL of 0.010 m calcium chloride with 100 mL of 1.0 x 10-5 m solution of potassium carbonate.

This is because the Ksp (solubility product constant) for calcium carbonate is 3.0 x 10-9. This means that when the concentrations of calcium and carbonate ions become too high, they will no longer be soluble and a precipitate will form. To understand this better, consider the following reaction:

CaCl2 (aq) + CO3 (aq) --> CaCO3 (s) + 2Cl- (aq).

This equation shows that calcium ions (Ca2+) from the calcium chloride solution will react with carbonate ions (CO3-) from the potassium carbonate solution to form solid calcium carbonate (CaCO3) and chloride ions (Cl-). When the concentrations of calcium and carbonate ions in the solution become too high, a precipitate will form as calcium carbonate.

The Ksp for calcium carbonate is a measure of how much calcium and carbonate ions can be present in the solution before a precipitate forms. This means that if the concentrations of the calcium and carbonate ions become greater than 3.0 x 10-9 molar, a precipitate will form. The concentrations of the calcium and carbonate ions in the given solutions are 0.010 m and 1.0 x 10-5 m respectively, both of which are greater than the Ksp of calcium carbonate and hence a precipitate will form.

According to the number of moles we can say that the limiting reagent is Cl as it has few moles.

Limiting agents are the reactant that determines the amount of the product in a reaction. In the reaction between magnesium and hydrochloric acid, the limiting reagent is HCl.

A limiting reagent is a substance that restricts or determines the amount of product formation in a reaction. They are the reactants with less number of moles and get consumed in the reaction before the other reactant.

The reaction between magnesium and hydrochloric acid is given by,

Mg(s) + 2HCl(aq)  → MgCl₂(aq) + H2(g)

Here, 1 mole of Mg and 2 moles of HCl are required to produce 1 mole of magnesium chloride.

The moles of Mg,

= 65.8 g ÷ 24.305

= 2.707 mol

And, moles of HCl

= 45.7 g ÷ 36.458

= 1.253 mol

The stoichiometric ratio Mg : HCl = 1:2

Hence, Mg = 2.707 ÷ 1 = 2.707  and HCl = 1.253 ÷ 2 = 0.6265

Balanced trade refers to a situation in which a country's income from exports is equal to its expenditure on imports. This equilibrium in trade is reflected in the country's balance of trade statement, which records the value of exports and imports of goods and services. The net export, representing the difference between total exports and total imports, can be positive or negative.

In economics, a trade deficit occurs when a country's total imports surpass its total exports. Conversely, a trade surplus happens when a country's total exports exceed its total imports. These imbalances in trade are indicators of the economic relationship a country has with other nations.

The trade balance is an important concept in a country's economy and is calculated by subtracting the value of imports from the value of exports. A trade surplus occurs when a country earns more from its exports than it spends on imports, leading to increased export revenue. On the other hand, a trade deficit arises when a country's spending on imports exceeds its income from exports.

It is important to note that balanced trade does not necessarily imply a positive or negative outcome. It simply indicates a state where export earnings match import expenditures. The implications of balanced trade depend on various factors, including the country's economic goals, competitiveness, and overall economic conditions.

The graph of the equation will remain the same, showing that x has not changed.

Given the equation y = kx²/z, if y and z are both doubled and k remains constant, then x remains unchanged. This can be shown mathematically by rearranging the equation for x to x = (yz/k). Since both y and z have doubled, their product also doubles and the equation becomes x = (2z2/k). Since k remains constant, the denominator remains the same and therefore the value of x is unchanged.

Given the equation y = kx²/z, if y and z are both doubled and k remains constant, then the value of x remains unchanged. This is because doubling y and z will cancel each other out, resulting in the equation remaining the same. Mathematically, this can be expressed as y = kx²/z and 2y = k(2x²)/(2z). Canceling out the 2s on both sides of the equation, we get y = kx²/z, which is the same equation as before. Therefore, the value of x remains unchanged.This can also be demonstrated graphically. If y and z are shown on the y-axis and x on the x-axis, then when y and z are both doubled, the graph of the equation will remain the same, showing that x has not changed.

The mole fraction of phosphoric acid (H₃PO₄) in a 25.4% (by mass) aqueous solution is C) 0.0589.

To calculate the mole fraction of phosphoric acid in a 25.4% (by mass) aqueous solution, we first need to determine the mass of phosphoric acid and water in the solution.

Assuming we have 100g of the solution, the mass of phosphoric acid would be:

Mass of H₃PO₄ = 25.4g (since the solution is 25.4% by mass)

The mass of water would be:

Mass of water = 100g - 25.4g = 74.6g

Next, we need to convert the masses of phosphoric acid and water into moles using their respective molar masses.

Molar mass of H₃PO₄ = 98.0 g/mol
Molar mass of H₂O = 18.0 g/mol

Moles of H₃PO₄ = 25.4g / 98.0 g/mol = 0.259 moles
Moles of H₂O = 74.6g / 18.0 g/mol = 4.14 moles

Finally, we can calculate the mole fraction of H₃PO₄ in the solution:

Mole fraction of H₃PO₄ = Moles of H₃PO₄ / (Moles of H₃PO₄ + Moles of H₂O) = 0.259 / (0.259 + 4.14) = 0.0589

Therefore, the mole fraction of phosphoric acid in the 25.4% (by mass) aqueous solution is 0.0589, which corresponds to answer choice C.

The correct equation representing the radioactive decay of 226Ra is (2)   226Ra → 222Rn + 4He.

This equation correctly represents the radioactive decay process of 226Ra (Radium-226) into 222Rn (Radon-222) and 4He (Helium-4).

In radioactive decay, unstable isotopes undergo a spontaneous process to transform into more stable forms by emitting particles or radiation. In the case of 226Ra, it decays by a process called alpha decay. Alpha decay involves the emission of an alpha particle, which consists of two protons and two neutrons (equivalent to a helium nucleus).

The equation (2) shows that 226Ra undergoes alpha decay, resulting in the formation of 222Rn and the release of an alpha particle (4He). The atomic number and mass number must be conserved in the decay process. Therefore, 226 (atomic number 88) on the left side of the equation decays to 222 (atomic number 86) on the right side, while the mass number also decreases by 4 units.

It's important to note that equation (1) represents an incorrect notation, as it suggests that 226Ra undergoes a transformation to 226Ra89, which is not possible as it implies an increase in atomic number. Equation (3) does not accurately represent the decay of 226Ra. Equation (4) is incorrect as it represents the formation of an isotope that doesn't exist.
