balanced equation for the decomposition of aluminium tetraoxosulphate​

The balanced equation of the redox reaction is given as follows:

The balanced equation of the reaction is determined using the half-reaction method.

The given equation of the redox reaction is:

H₆TeO₆ + Br₂ ----> TeO₂ + BrO₃⁻

Reduction half-reaction:

H₆TeO₆ → TeO₂

The oxidation state of Te changes from +6 to +4, showing that it has lost gained electrons.

H₆TeO₆ → TeO₂ + 2e⁻

Oxidation half-reaction:

Br₂ → BrO₃⁻

The oxidation state of Br changes from 0 to +5, showing that it has lost five electrons.

Balancing the electrons transferred and the atoms by adding electrons, H₂O, and H⁺ to the appropriate sides:

Br₂ + 6 H₂O → 2 BrO₃⁻ + 12 H⁺ + 10 e⁻

The number of electrons transferred in both half-reactions balanced is  by multiplying the oxidation half-reaction by 5 and the reduction half-reaction by 2:

5 (H₆TeO₆ → TeO₂ + 2 e⁻) → 5 H₆TeO₆ → 5 TeO₂ + 10 e⁻

2 * (Br₂ + 6H₂O → 2 BrO₃⁻ + 12 H⁺ + 10e⁻) → 2 Br₂ + 12 H₂O → 4 BrO₃⁻ + 24 H⁺ + 20 e⁻

The two half-reactions are added together and the electrons are canceled out to obtain the balanced redox reaction:

5 H₆TeO₆ + 2 Br₂ + 12 H₂O → 5 TeO₂ + 4 BrO₃⁻ + 24 H⁺

Answer:

The value of x in the hydrocarbon formula CxHy is 1.

Explanation:

Here's how to arrive at the solution:

Since the relative atomic mass of carbon is 12 and the hydrocarbon contains 9g of carbon, we know that there are 9/12 = 0.75 moles of carbon in the hydrocarbon.

Since the hydrocarbon only contains hydrogen and carbon, the remaining mass (12g - 9g = 3g) must be due to hydrogen.

To find the number of moles of hydrogen, we need to convert the mass of hydrogen to moles. The relative atomic mass of hydrogen is 1, so the number of moles of hydrogen is 3/1 = 3 moles.

Therefore, the ratio of carbon to hydrogen in the hydrocarbon is 0.75 moles of carbon to 3 moles of hydrogen, which simplifies to 1:4.

The general formula for the hydrocarbon can be written as CxHy. Since the ratio of carbon to hydrogen is 1:4, we know that x = 1 and y = 4. Thanks.

Explanation:

At equilibrium, the number of moles of \(Cl_2\) (g) will be 0.2025 mol.

1: Write the balanced chemical equation:

\(C_O\)(g) + \(Cl_2\)(g) ⟶ \(C_OCl_2\)(g)

2: Set up an ICE table to track the changes in moles of the substances involved in the reaction.

Initial:

\(C_O\)(g) = 0.3500 mol

\(Cl_2\)(g) = 0.05500 mol

\(C_OCl_2\)(g) = 0 mol

Change:

\(C_O\)(g) = -x

\(Cl_2\)(g) = -x

\(C_OCl_2\)(g) = +x

Equilibrium:

\(C_O\)(g) = 0.3500 - x mol

\(Cl_2\)(g) = 0.05500 - x mol

\(C_OCl_2\)(g) = x mol

3: Write the expression for the equilibrium constant (Kc) using the concentrations of the species involved:

Kc = [\(C_OCl_2\)(g)] / [\(C_O\)(g)] * [\(Cl_2\)(g)]

4: Substitute the given equilibrium constant (Kc) value into the expression:

1.2 x \(10^3\) = x / (0.3500 - x) * (0.05500 - x)

5: Solve the equation for x. Rearrange the equation to obtain a quadratic equation:

1.2 x \(10^3\) * (0.3500 - x) * (0.05500 - x) = x

6: Simplify and solve the quadratic equation. This can be done by multiplying out the terms, rearranging the equation to standard quadratic form, and then using the quadratic formula.

7: After solving the quadratic equation, you will find two possible values for x. However, since the number of moles cannot be negative, we discard the negative solution.

8: The positive value of x represents the number of moles of \(Cl_2\)(g) at equilibrium. Substitute the value of x into the expression for \(Cl_2\)(g):

\(Cl_2\)(g) = 0.05500 - x

9: Calculate the value of \(Cl_2\)(g) at equilibrium:

\(Cl_2\)(g) = 0.05500 - x

\(Cl_2\)(g) = 0.05500 - (positive value of x)

10: Calculate the final value of \(Cl_2\) (g) at equilibrium to get the answer.

Therefore, at equilibrium, the number of moles of \(Cl_2\) (g) will be 0.2025 mol.

Answer:

The molecular formula for A is C2H4(NO3)2

The molecular formula for B is C2H6O2

Explanation:

I linked an image that will show the work.

Answer:

Explanation:

To determine the amount of chlorine needed to make 75.0 grams of C2H2Cl4, we need to balance the chemical equation and then use the molar ratio between the reactants and product to find the amount of Cl2 needed.

The balanced equation is:

2 Cl2(g) + C2H2(g) -> C2H2Cl4(l)

Next, we can use the molar mass of C2H2Cl4 to find the number of moles of C2H2Cl4 produced:

75.0 g C2H2Cl4 x (1 mole C2H2Cl4 / 153.8 g C2H2Cl4) = 0.489 moles C2H2Cl4

Since the balanced equation has a 1:2 ratio of C2H2 to Cl2, this means that we need 2 moles of Cl2 for every mole of C2H2Cl4 produced. Therefore, we will need 2 x 0.489 moles = 0.978 moles of Cl2.

Finally, to find the volume of Cl2 at STP, we can use the ideal gas law:

PV = nRT

Where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant (0.0821 L-atm/mol-K), and T is the temperature in Kelvin (273 K).

Since the pressure is 1 atm and the temperature is 273 K, we can rearrange the equation to solve for volume:

V = nRT / P = 0.978 moles x 0.0821 L-atm/mol-K x 273 K / 1 atm = 17.1 L

Therefore, 17.1 liters of Cl2 at STP will be needed to make 75.0 grams of C2H2Cl4.

J.J. Thomson discovered electrons and their negative charge through the cathode ray experiment, leading to the development of the plum pudding model of the atom.

J.J. Thomson, a British physicist, was the first to discover electrons in 1897.

He conducted the cathode ray experiment to identify the negatively charged particles.

The cathode ray tube is a vacuum-sealed glass tube with two electrodes at each end: a cathode and an anode.

When a high voltage electrical current is applied to the electrodes, the tube glows, indicating that the cathode rays are being emitted from the cathode and traveling through the tube towards the anode.

The cathode rays were found to have a negative charge, according to Thomson.

These rays were identified as particles by the presence of a magnet, which caused the particles to bend in the direction opposite to the magnet's polarity.

This discovery indicated that the particles had a charge on them because they were deflected by the magnetic field, which is only possible if the particles have an electric charge.

Thomson further concluded that these particles were about 1,000 times smaller than hydrogen atoms because of the degree of deflection they experienced in the magnetic field.

Furthermore, Thomson created the plum pudding model of an atom, in which electrons are dispersed throughout a positively charged matrix, based on his findings.

Answer:

Density of the solid is 1.63g/mL

Explanation:

Hello,

Data;

Mass of solid = 32.65g

Mass of toluene = ?

Mass of solid + toluene = 58.58g

Density of toluene = 0.864g/mL

Mass of toluene = (mass of solid + toluene) - mass of solid

Mass of toluene = 58.58 - 32.65

Mass of toluene = 25.93g

But density = mass / volume

Density of toluene = mass of toluene / volume of toluene

Volume of toluene = mass of toluene / density of toluene

Volume of toluene = 25.93 / 0.864

Volume of toluene = 30.01mL

Volume of solid = total volume of the mixture (solid + toluene) - volume of toluene

Volume of solid = 50 - 30.01

Volume of solid = 19.99mL

Density of the solid = mass of solid / volume of solid

Density of the solid = 32.65 / 19.99

Density of the solid = 1.63g/mL

Therefore the density of the solid is 1.63g/mL

Explanation:

According to the kinetic molecular theory, the particles of a gas are in constant random motion and possess kinetic energy. This kinetic energy is directly proportional to the temperature of the gas.

If the sample of gas is at a constant temperature and volume, it means that the average kinetic energy of its particles is constant.

C, it has a constant average kinetic energy is the correct statement.

Explanation: The kinetic molecular theory of gases states that a gas contains an enormous number of atoms/molecules.

The kinetic-molecular theory of gases can be stated as such: A gas consists of molecules in constant random motion. Gas molecules influence each other only by collision; they exert no other forces on each other. All collisions between gas molecules are perfectly elastic; all kinetic energy is conserved.

Approximately 35.2% of the Kcalories in a small order of McDonald's French fries come from fat.

Consuming a high amount of calories over a prolonged period can be harmful to your health in several ways:

Weight gain and obesity: Consuming more calories than your body needs can lead to weight gain and eventually obesity.

Cardiovascular disease: increased risk of developing cardiovascular disease.

Insulin resistance and type 2 diabetes: Consuming too many calories, particularly from sources such as refined carbohydrates and sugary drinks, can lead to insulin resistance.

Digestive problems: digestive problems such as constipation, bloating, and diarrhea.

Reduced lifespan: Studies have shown that consuming a high amount of calories can lead to a reduced lifespan.

To calculate the percentage of kcalories from fat in French fries, we need to know the total number of kcalories in the French fries and the number of kcalories that come from fat.

Assuming that the French fries contain 9 grams of fat per serving (which is the amount of fat in a medium order of McDonald's French fries), we can calculate the number of kcalories from fat as follows:

9 grams of fat x 9 kcalories per gram of fat = 81 kcalories from fat

If the French fries contain 230 kcalories per serving (which is the amount of calories in a small order of McDonald's French fries), we can calculate the percentage of kcalories from fat as follows:

81 kcalories from fat ÷ 230 total kcalories = 0.352 or 35.2%

17.42 grams of water (H₂O) will be produced when 35.8 grams of calcium hydroxide (Ca(OH)₂) reacts with hydrochloric acid.

Given,

Mass of calcium hydroxide (Ca(OH)₂) = 35.8 grams

Molar mass of calcium hydroxide (Ca(OH)₂) = 74.10 g/mol

Molar mass of water (H₂O) = 18.02 g/mol

The balanced equation for the reaction between calcium hydroxide and hydrochloric acid is: Ca(OH)₂ + 2HCl → CaCl₂ + 2H₂O

For every 1 mole of calcium hydroxide that reacts, 2 moles of water are produced.

Moles = Mass / Molar mass

Moles of Ca(OH)₂ = 35.8/ 74.10 ≈ 0.483 mol

Moles of H₂O = 2 × Moles of Ca(OH)₂ = 2 × 0.483 = 0.966 mol

Answer: 7.52*10^23 molecules.

Explanation: This is a classic Stoichiometry problem.

In one mole of any substance, there are 6.02*10^23 molecules. This number is called Avogadro's number. We are given 55 grams of Co2 so to convert that to moles, we divided by the molar mass of Co2. We find the molar mass by adding the molar masses of the elements that make up the compound.

There is one molecule of Carbon and two molecules of Oxygen in one molecule of Co2. From the periodic table, the molar mass of Carbon is 12.01 and 16.00 for Oxygen. 1(12.01)+2(16.00) gives us the molar mass. We then divided 55 grams by that mass to find the number of moles. We then multiply the number of moles by Avogadro's number (6.02*10^23) to find the total number of molecules.

You can use this method for solving any problem that asks you to find the number of atoms or molecules of some number of grams of a substance.

The ideal gas law may be used to determine the volume of oxygen created in the electrolysis that produces 548 litres of hydrogen at STP (Standard Temperature and Pressure). PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature, according to the ideal gas equation.

The pressure is 1 atm, the temperature is 273 K, and the number of moles of hydrogen is 548/22.4 = 24.5 in this example. We may compute the volume of oxygen created by rearranging the ideal gas law: V = nRT/P = 24.5*0.082*273/1 = 483.3 litres.
