Cuántos moles de hipoclorito de sodio (NaCIO)se generan cuando reaccionan 5 moles de NaOH​

Answer:

False

Explanation:

The increase in the temperature of a liquid also increases the rate of evaporation, as the same for the other way around.  As intermolecular force increase rate of evaporation decreases. This happens because intermolecular force make it less likely for the molecules on the surface to escape from liquid and become vapour gas. As temperature increases rate of evaporation increases.

The statement, that describes the characteristic of a strong acid is "it completely dissociates in water."

What is a strong acid?

In aqueous solution, strong acids and bases are completely ionised.

A strong acid is one that entirely ionises in solution. When dissolved in water, it emits the maximum number of hydrogen ions or protons, implying that it always loses a proton (H+).

As a result, it is possible to deduce that a strong acid (HA) entirely dissociates in solution.

Hence the correct option is B.

The reaction that has been shown in the table above is a double replacement reaction, and each compound has the same set of ions. Option D

Another word that we can use for reaction is what we call a chemical change. We know that a chemical change is the kind of change that will lead to the formation of a new product. It is an irreversible process as we can not be able to get back the reactants again.

We should note that there are various types of reactions. In a single  replacement reaction, you would notice that there is only one substance that reacts and causes a change while in the double replacement reaction, the anions that are in the compounds that underwent the reaction would just exchange anion partners and we would have two ionic products.

Mass (often measured in grams) & volume are the two characteristics in this module through which we will create unit components to do statistical approach using different chemicals .

Chemical substances come in three different forms: elements, compounds, and mixtures. Elements are basically chemicals that don't contain any other substances. In this sense, elements are the fundamental constituents of chemical composition.

The component can be an isotope or a combination if it is pure. If a substance can be divided into its component elements, it is a compound. If a substance is not chemically pure, it is either a heterogeneous mixture or even a heterogeneous mixture. If the composition remains the same throughout, the combination is homogeneous.

When ocean water that is more dense (colder or saltier) is mixed with water that is less dense (warmer or less salty), the denser water will sink to the bottom and the less dense water will rise to the top. This is known as stratification, and it helps to create distinct layers in the ocean.

This stratification can create an environment that is more conducive to life, as it allows different types of organisms to inhabit different layers of the ocean.

The different layers of the ocean created by stratification play a significant role in the global climate system. Colder, denser waters are usually found at the bottom of the ocean, while warmer, less dense waters are found near the surface.

This temperature difference creates a natural convection system that drives currents throughout the ocean, which helps to regulate temperatures on a global scale. Additionally, stratification can also affect the amount of oxygen in the ocean.

Explanation:

You want the coefficient of silver iodide in the equation ...

  _AgI +_Na₂S ⇒ _Ag₂S +_NaI

The equation is balanced when the numbers of each of the species is the same on each side of the equation.

We can write four equations in the four unknowns to find the coefficients, or we can use a little guesswork.

If we suppose the coefficient of silver sulfide (Ag₂S) is 1, that tells us the coefficient of silver iodide (AgI) will be 2. If that is the case, then there are two atoms of iodine that will make the coefficient of NaI be 2. This is consistent with the coefficient of Na₂S being 1, giving one Sulfur atom on each side of the equation.

The balanced equation is ...

  2AgI +Na₂S ⇒ Ag₂S +2NaI

The coefficient of silver iodide is 2.

__

Additional comment

If the reaction is ...

  a·AgI + b·Na₂S ⇒ c·Ag₂S + d·NaI

We can write the relationships between the coefficients as follows. This ultimately gives rise to 3 equations in 4 unknowns, so the choice of any given coefficient is arbitrary. We choose to use the smallest integers that satisfy the conditions.

The balance for Ag is ...

  a = 2c

The balance for I is ...

  a = d

The balance for Na is ...

  2b = d

The balance for S is ...

  b = c

Then, in terms of 'a' and 'b', we have ...

  a = d = 2b = 2c

For b = c = 1, a = d = 2, as we determined above.

The amount of hydrogen monochloride that is produced at STP is 152 mL.

A chemical reaction reaches equilibrium when the rate of the forward reaction is equal to the rate of the reverse reaction, resulting in no net change in the concentrations of the reactants and products.

A scientist observing a chemical reaction can tell if the reaction has achieved equilibrium by monitoring the following: Concentration of reactants and products: The concentrations of reactants and products should no longer change over time if the reaction has reached equilibrium. Temperature: If the reaction has reached equilibrium, the temperature of the system should remain constant. Pressure: If the reaction is taking place in a closed container, the pressure of the system should also remain constant if the reaction has reached equilibrium. It's worth noting that the equilibrium is a dynamic process, meaning that the concentrations of reactants and products will remain constant over time, but the chemical reaction is still taking place.

Several ways are:-

1. Decreasing the surface area of the marble chips: By breaking the marble chips into smaller pieces, the surface area that is available for the acid to react with is reduced, slowing down the reaction.

2. Decreasing the concentration of the hydrochloric acid: By using a less concentrated solution of hydrochloric acid, the number of acid molecules available to react with the marble chips is reduced, slowing down the reaction.

3. Increasing the temperature: By performing the reaction at a lower temperature, the kinetic energy of the acid and marble chip molecules is reduced, slowing down the rate of collision between them, which slows down the reaction.

4. Using a catalyst: Addition of a catalyst to the reaction can change the reaction mechanism and decrease the activation energy needed for the reaction to occur, thus slowing down the reaction.

5. Using an inhibitor: An inhibitor is a substance that slows down the reaction by binding to the enzyme or catalytic site and preventing the substrate from binding.

On this scenario, the US may consume more than its PPC by specializing in cheese and swapping it for Italian tomatoes.

Italy’s cheese output is lower than that of the United States.Italy cannot consume cheese other than PPC unless these products are supplied by another nation. Through an exchange deal with Italy, the United States can enjoy tomatoes in addition to PPC. Because cheese production in the United States is substantially higher than in Italy, we may assume that the United States can offer this commodity to other nations without jeopardizing its consumption. However, tomato output in the United States is the same as in Italy, but because the United States is a larger country than Italy, tomato consumption in the country may be affected.

As a result, if tomatoes are obtained from another nation, tomato consumption in the United States may surpass the PPC of tomatoes. This may be accomplished through barter, with the United States supplying cheese to Italy and Italy supplying tomatoes to the United States.
