The refrigerator would use 180 kilowatt-hours (kWh) of electric energy over the course of 30 days, assuming it runs for 12 hours each day.

To calculate the kilowatt-hours (kWh) of electric energy used by the refrigerator in 30 days, we need to multiply the power rating by the total running time.

Given:

Power rating of the refrigerator = 500 W

Running time per day = 12 hours

Number of days = 30

First, we need to convert the power rating from watts to kilowatts:

Power rating = 500 W / 1000 = 0.5 kW

Next, we calculate the total energy used in kilowatt-hours (kWh) over the 30-day period:

Energy used = Power rating × Running time × Number of days

Energy used = 0.5 kW × 12 hours/day × 30 days

Energy used = 180 kWh

Therefore, the refrigerator would use 180 kilowatt-hours (kWh) of electric energy over the course of 30 days, assuming it runs for 12 hours each day.

Explanation:

17. They reach to form Fe2O3

18. I think they dont reach

Answer:

If a gas contracts by 1/273 of its volume for each degree of cooling, it should contract to zero volume at a temperature of –273°C; this is the lowest possible temperature in the universe, known as absolute zero.It appeared that an “ideal gas” at constant pressure would reach zero volume at what is now called the absolute zero of temperature. Any real gas actually condenses to a liquid or a solid at some temperature higher than absolute zero. Therefore, the ideal gas law is only an approximation to real gas behaviour.

The partial pressure inside a gas mixture shall consist of the notional pressure of that constituent gas if the whole quantity of its starting material alone was occupied at the same temperature. The partial gas pressure is a measure of thermodynamic action in the particles of a gas, and the calculation can be defined as follows:

Given:

\(\to \bold{ P_T=3.50 \ atm}\\\\\to \bold{P_B=1.25 \ atm}\\\\\)

To find:

partial pressure=?

Solution:

Using formula: \(\bold{P_T=P_A+P_B}\\\\\)

                   \(\to \bold{3.50=P_A+1.25}\\\\\to \bold{P_A=3.50-1.25}\\\\\to \bold{P_A=2.25}\\\\\)

As we know that pressure is not negative and as \(\bold{P_T}\) is total pressure so, it has a large value, and\(\bold{ P_A , P_B}\) is partial.

Therefore, the final answer is "Option C".

Acid-base reactions are a fundamental class of chemical reactions that are prevalent in nature and play a critical role in many industrial processes.

The reactivity of an acid-base reaction is a function of the electron distribution of the reactants. In general, acids are electron-deficient species that have an affinity for electrons, while bases are electron-rich species that readily donate their electrons.

The base is an electron-rich species that can readily donate its electrons to an electron-deficient acid, resulting in the formation of a new compound.

This process is typically accompanied by the release of energy in the form of heat and light. The electron donation process results in the formation of a new bond between the acid and the base, and the formation of a new compound.

In an acid-base reaction, the electron-rich base species reacts readily with the electron-deficient acid species to form a new compound. This reactivity trend is observed across a wide range of acid-base reactions and is a fundamental concept in chemistry.

Understanding the electron distribution of the reactants is critical in predicting the reactivity of acid-base reactions and in designing chemical processes that utilize these reactions. Overall, acid-base reactions are a critical class of chemical reactions that play an essential role in many industrial processes and in our understanding of the natural world.

Hydrogen bonding is distinguished from other permanent dipole interactions by the involvement of hydrogen atoms bonded to highly electronegative atoms (such as nitrogen, oxygen, or fluorine).

Hydrogen bonding is a specific type of intermolecular force that occurs between a hydrogen atom and an electronegative atom in a different molecule or chemical group. It is stronger than other types of permanent dipole interactions because of the large electronegativity difference between hydrogen and the electronegative atom it is bonded to.

In hydrogen bonding, the hydrogen atom carries a partial positive charge due to the electronegativity difference, while the electronegative atom carries a partial negative charge. This creates a strong electrostatic attraction between the positive hydrogen and the negative electronegative atom.

Hydrogen bonding is responsible for many unique properties and behaviors of substances. For example, it plays a crucial role in the high boiling points of water and ammonia, as well as the unique properties of DNA and proteins. It also contributes to the solubility of certain compounds and influences the physical and chemical properties of molecules.

The key distinction of hydrogen bonding from other permanent dipole interactions is the involvement of a hydrogen atom bonded to an electronegative atom. This specific interaction results in stronger intermolecular forces and has significant implications for the properties and behavior of substances.

Explanation:

For every iodate ion consumed by the reaction with iodine and acid, only 3 thiosulfate ions are consumed by reaction with iodine.

For every iodate ion consumed by the reaction with iodine and acid, 3 thiosulfate ions are consumed by reaction with iodine. This is because the balanced chemical equation for the reaction between iodate and thiosulfate is:
IO₃⁻ + 6S2O₃²⁻ + 6H+ → I⁻ + 3S₄O₆²⁻ + 3H₂O
As you can see, for every iodate ion (IO3-) consumed, 6 thiosulfate ions (S₂O₃²⁻) are consumed. However, in the reaction between iodine and thiosulfate, each molecule of thiosulfate (S₂O₃²⁻) can only react with one molecule of iodine (I2) according to the following balanced chemical equation:
2S₂O₃²⁻ + I2 → S₄O₆²⁻+ 2I⁻
Therefore, for every iodate ion consumed by the reaction with iodine and acid, only 3 thiosulfate ions are consumed by reaction with iodine.

Sodium hydroxide is a strong base that readily absorbs water vapor from the atmosphere and dissolves in water. Its molarity can be determined by adding a known amount of acid of a known concentration to a sample of the sodium hydroxide solution and then titrating it until the equivalence point is reached.

However, there are several reasons why you can't accurately determine the molarity of sodium hydroxide using the number of grams dissolved in the total amount of solution. Here are a few:

1. Impurities and water content: Sodium hydroxide pellets, flakes, or crystals often contain impurities that can affect its molarity. Also, the substance absorbs water vapor from the atmosphere, which can lead to inaccurate molarity measurements.

2. Difficulty in dissolving: Sodium hydroxide is not very soluble in water, which means that it can be difficult to dissolve an accurate amount of it in a given volume of water. This can result in an inaccurate measurement of its molarity.

3. Concentration changes: The concentration of a sodium hydroxide solution can change due to changes in temperature, pressure, or concentration. This can lead to an inaccurate measurement of its molarity.

4. Reaction with glassware: Sodium hydroxide can react with glassware, which can affect its molarity measurement. In conclusion, it is not recommended to determine the molarity of sodium hydroxide using the number of grams dissolved in the total amount of solution, as it can lead to inaccurate results. Instead, titration with a known amount of acid is a more reliable method to determine its molarity.

The mass of sodium sulfate required to form 250 mL of solution in which the concentration of sodium ions is 0.183 would be  3.25 grams.

Sodium sulfate is made up of sodium and sulfate ions according to the following equation:

\(Na_2SO_4 --- > 2Na^+ + SO_4^2^-\)

From the equation above, a mole of sodium sulfate is made from 2 moles of sodium ions and 1 mole of sulfate ions.

Recall that: mole = molarity x volume

The mole of 0.183 M sodium ion in 250 mL os solution would be:

0.250 x 0.183 =  0.04575 mol

The equivalent mole of sodium sulfate would be:

0.04575/2 = 0.022875 mol

Recall that: mass = mole x molar mass

The molar mass of sodium sulfate is 142.04 g/mol

Mass of 0.022875 mol sodium sulfate = 0.022875 x 142.04

                                                                = 3.249165 grams

Answer:

[HClO₄] = 0.35 M

Explanation:

Neutralization reaction is:

HClO₄ + LiOH  →  LiClO₄  +  H₂O

In this case, we have a titration between a weak acid and a strong base.

In chemistry it is also called an acid base equilibrium.

HClO₄  +  H₂O  ⇄  ClO₄⁻   +  H₃O⁺       Ka

The weak acid is firstly neutralized by the strong base, in order to have a buffer solution before the equivalence point.

When we reach the equivalence point, mmoles of acid = mmoles of base and there is a formula to determine it so:

M acid . Volume of acid = M base . Volume of base

M acid . 100 mL = 0.75 M . 46.9 mL

M acid = (0.75 M . 46.9 mL) / 100 mL → 0.35 M

Of the molecules given below, the bond in HF is the most polar. Option D) is correct.

Polarity is the extent to which different atoms' electrons are shared in a chemical bond. In a molecule, the unequal distribution of charge leads to a dipole moment. The greater the electronegativity difference between the bonded atoms, the more polar the bond and molecule become.

A polar bond is created when two atoms with different electronegativity values join together. The atom with a greater electronegativity has a stronger pull on the shared electrons in the bond, resulting in a partial negative charge, while the atom with a lower electronegativity has a partial positive charge.

Fluorine is the most electronegative element on the periodic table. The electronegativity values of the elements in the bond between HF are 2.20 and 0.98 for fluorine and hydrogen, respectively. Because there is such a significant difference in electronegativity, the bond between them is highly polar.

Hence, of the molecules listed above, the bond in HF is the most polar. Hence, option D) is correct.
