The standard reduction potential for the half-reaction M3+(aq) + 3e- → M(s) can be determined by subtracting the standard reduction potential of the half-reaction Ag+(aq) + e- → Ag(s) from the overall reaction's standard potential.

Given:

E°(overall reaction) = +2.46 V (from the balanced equation)

E°(Ag+(aq) + e- → Ag(s)) = +0.80 V (given)

To find E°(M3+(aq) + 3e- → M(s)):

E°(M3+(aq) + 3e- → M(s)) = E°(overall reaction) - E°(Ag+(aq) + e- → Ag(s))

E°(M3+(aq) + 3e- → M(s)) = +2.46 V - (+0.80 V)

E°(M3+(aq) + 3e- → M(s)) = +1.66 V

Therefore, the standard reduction potential for the half-reaction M3+(aq) + 3e- → M(s) is +1.66 V.

The pressure of the gas in the flask in kilopascals is given by the term 100.3 kPa, option E.

The pressure of any gas is a crucial characteristic. In contrast to qualities like viscosity and compressibility, we have some experience with gas pressure. Every day, the TV meteorologist reports the value of the atmosphere's barometric pressure.

We have included numerous slides on gas pressure in the Beginner's Guide since comprehending what pressure is and how it works is so essential to understanding aerodynamics. It is possible to investigate how static air pressure varies with altitude using an interactive atmosphere simulator. You can see how the pressure changes around a lifting wing using the FoilSim software.

height difference, h, indicates pressure of gas relative to atmospheric pressure.

h= 13mm

barometric pressure =765.2mmHg (atmosphere)

-from the picture, we can see that atmospheric pressure is greater than the gas pressure. so we minus

765.2mm - 13mm= 752.2mmHg

752.2mmHg * (101.3kPa / 760mmHg) = 100.3kPa.

To balance this equation, we need to ensure that the number of atoms of each element is equal on both sides of the equation. Here's how to balance it step by step:

Balance the Copper atoms: There is 1 Copper atom on each side, so no changes are needed.

Cu + H₂SO4 → CuSO4 + SO2 + H₂

Balance the Sulfur atoms: There is 1 Sulfur atom on each side, so no changes are needed.

Cu + H₂SO4 → CuSO4 + SO2 + H₂

Balance the Hydrogen atoms: There are 2 Hydrogen atoms on the right side, but only 1 on the left. We can balance this by adding a coefficient of 2 in front of H₂.

Cu + H₂SO4 → CuSO4 + SO2 + 2H₂

Balance the Oxygen atoms: There are 4 Oxygen atoms on the right side, but only 2 on the left. We can balance this by adding a coefficient of 2 in front of CuSO4 and a coefficient of 1/2 in front of SO2.

Cu + H₂SO4 → 2CuSO4 + SO2 + 2H₂

Now the equation is balanced, with 1 Copper atom, 1 Sulfur atom, 4 Hydrogen atoms, and 6 Oxygen atoms on each side. I hope this helps, and good luck on your final exam tomorrow!

When the temperature conversion function =CONVERT(-22, "C", "F") is applied, a reading of -22 °C in Fahrenheit is displayed. On a variety of scales, including the Fahrenheit and Celsius systems, temperature is a unit that is used to denote hotness or coolness.

Heat energy will logically go from a hotter (body with a higher temperature) to a colder (body with a lower temperature) according to temperature (one at a lower temperature).

A temperature is a measurement used to express how hot or cold something is. It demonstrates how heat energy naturally flows from a hotter body to a cooler body and can be expressed in terms of any number of arbitrary scales (one at a lower temperature).

A match is burning at a far greater temperature than an iceberg, yet an iceberg has a significantly higher total heat energy than a match. Temperature is not the same as the energy of a thermodynamic system.

The temperature, along with pressure, density, and other similar properties, is referred to as an intense property as opposed to extensive characteristics like mass or volume—one that is independent of the quantity of stuff being addressed.

Answer:

Oxidation half-reaction : Na(s) → Na⁺ + 1 e-

Reduction half-reaction: Cl₂ + 2 e- → 2 Cl⁻

Explanation:

Oxidation half-reaction: solid sodium (Na(s)) has an oxidation number of 0. It loses 1 electron and forms the cation Na⁺. So, the half-reaction is the following:

Na(s) → Na⁺ + 1 e-

Reduction half-reaction: chlorine gas (Cl₂) has an oxidation number of 0. Each atom of Cl gains 1 electron to form two Cl⁻ ions, according to the following half-reaction:

Cl₂ + 2 e- → 2 Cl⁻

The total oxidation-reduction reaction is obtained by adding the oxidation half-reaction multiplied by 2 (to balance the electrons) and the reduction half-reaction, as follows:

2 x (Na(s) → Na⁺ + 1 e-)

Cl₂ + 2 e- → 2 Cl⁻

A chemical reaction is said to be in a state of dynamic equilibrium when the forward and reverse reactions are occurring at the same rate and there is no net change over time in the reactant and product concentrations. It is a dynamic state because individual molecules are constantly conducting reactions, despite the fact that the concentrations of reactants and products are constant.

In a chemical reaction, reactants undergo a forward reaction in which they are transformed into products, and products undergo a reverse reaction in which they are transformed back into reactants.

Answer:Because you need that certain number and double the number of bread to get the reactants off of the sides

Explanation: 4 bread reactants- 2meat reactants- 2 cheese reactants= 2 products

The reason for the presence of a certain number of reactants on one side is to ensure that the chemical equation is balanced.

In a balanced chemical equation, the number of atoms of each element on the reactant side must be equal to the number of atoms of that element on the product side.

Consider the equation:

\(2H_2 + O_2 - > 2H_2O.\)

This equation represents the reaction of hydrogen gas (\(H_2\)) with oxygen gas (\(O_2\)) to form water (\(H_2O\)).

To balance this equation, double the coefficient in front of \(H_2O\) on the product side, resulting in 4 hydrogen atoms and 2 oxygen atoms on both sides.

Therefore, having a certain number of reactants on one side is necessary to ensure that a chemical equation is balanced, satisfying the law of conservation of mass.

Answer:

CuCi2 + H2S ⇒ CuS + 2HCi

Explanation:

In order to balance a chemical equation you need to make sure to have the same number of atoms on each side by multiplying on both sides.

CuCi2 + H2S = CuS + HCi

Cu = 1

Ci = 2

H = 2

S = 1

Product

Cu = 1

S = 1

H = 1 × 2 = 2

Ci = 1 × 2 = 2

Since all elements have a balanced amount of atoms, the equation is now balanced.

CuCi2 + H2S ⇒ CuS + 2HCi

Answer:

a. 25.5 moles of Pb will be formed.

b. 54.8 moles of PbO are needed.

c. PbS is the limiting reactant.

Explanation:

1st) It is necessary to write the balanced chemical reaction:

From the balanced chemical reaction we know that 1 mole of PbS reacts with 2 moles of PbO to produce three moles of Pb and 1 mole of SO2.

2nd) Using the stoichiometry of the reaction and a mathematical rule of three, we can calculate the moles of Pb that will be produced from 17 moles of PbO and excess of PbS:

So, 25.5 moles of Pb will be formed.

3rd) Using the stoichiometry of the reaction and a mathematical rule of three, we can calculate the moles of PbO that are needed to make 27.4 moles of SO2 in excess of PbS:

So, 54.8 moles of PbO are needed.

4th) Using the stoichiometry of the reaction we can calculate the limiting reactant:

- Calculation from 17.6 moles of PbS:

From the stoichiometry of the reaction 1 mol of PbS reacts with 2 moles of PbO, so the 17.6 moles of PbS will need 35.2 moles of PbO to react properly, but we have 36g of PbO, so PbO will be the excess reactant and PbS the limiting reactant.

- Calculation from 36 moles of PbO:

We can do this calculation to confirm the previous one:

In this case, we can see that 36 moles of PbO will need 18 moles of PbS to react properly, but we only have 17.6 moles of PbS. Here we confirm that PbS is the limiting reactant.

Answer:

removing thermal energy will cause its particles to move more slowly and its temperature to drop

When thermal energy is removed from a substance the energy of the system will be low and particles of the substance will not move properly because of low energy.

Thermal energy is a type of energy that is mainly produced by the generation of the temperature as it is only responsible for the production of heat which is responsible for thermal energy production.

Energy provides the particles of a substance to move from one place to another place which is not possible without energy or heat or thermal energy and the process will not be complete.

Therefore, the energy of the system will be low and particles of the substance will not move properly because of the low energy When thermal energy is removed from a substance.
