Answer:

Explanation:

Endothermic reactions:

The type of reactions in which energy is absorbed are called endothermic reactions.

In this type of reaction energy needed to break the bond are higher than the energy released during bond formation.

For example:

C + H₂O   →  CO  + H₂

ΔH = +131 kj/mol

it can be written as,

C +  H₂O  + 131 kj/mol  →  CO  + H₂

Exothermic reaction:

The type of reactions in which energy is released are called exothermic reactions.

In this type of reaction energy needed to break the bonds are less than the energy released during the bond formation.

For example:

Chemical equation:

C + O₂   →  CO₂

ΔH = -393 Kj/mol

it can be written as,

C + O₂   →  CO₂ + 393 Kj/mol

There are three chirality centers in the structure: The carbon atom at the center of the molecule, the nitrogen atom at the top of the molecule, the oxygen atom at the bottom of the molecule.

What is structure?
Structure is the arrangement of components within a system. It is used to define the layout, connections and interactions of those components, in order to achieve a certain purpose. Structures can be physical, such as the structure of a bridge, or abstract, such as the structure of a story. Structures can be simple or complex and can involve multiple levels of inter-related components. For example, a business may have a hierarchical organizational structure with a CEO at the top, followed by a board of directors and then various departments and teams. Structure is an important part of any system because it helps to create order and organization, and provides clarity and understanding.

Among the options provided, the statement that accurately describes a type of potential energy found in a container full of a chemical substance in liquid form is: "The bonds between atoms are one place where potential energy is stored."

In a container filled with a chemical substance in liquid form, the potential energy is primarily stored in the bonds between atoms within the molecules of the substance. These bonds are formed by the sharing or transferring of electrons between atoms, creating a stable arrangement. The potential energy arises from the electrostatic interactions between the charged particles involved in these chemical bonds.When the liquid substance is in its equilibrium state, the potential energy stored in the bonds represents the energy required to break these bonds and separate the atoms, transforming the substance into a different state (such as a gas or a solid).

This potential energy is released when the substance undergoes a chemical reaction or when external forces act upon it.While other forms of potential energy can also exist in a liquid substance, such as kinetic energy due to the speed of the particles or vibrational energy of the atoms within the molecules, these are generally associated with other types of energy rather than potential energy.

The kind of material used to bake food will influence how much energy is required to heat it up and how quickly it cools. Due to the fact that metal conducts heat more effectively than glass, heating up metal pans often takes longer than heating up glass ovenware.

This implies that the metal absorbs heat from the oven more rapidly and effectively, needing more energy to attain the appropriate temperature. However, oven-safe glass will cool down more quickly than metal.

This is due to the fact that glass is a poor heat conductor, which means it takes more time for the heat to be absorbed by the glass. The glass will shatter after the dish is cooked and the heat is turned off.As the heat takes longer to dissipate, the metal cools down more quickly than the other materials.

In conclusion, glass cools more quickly than metal and requires less energy to heat up than oven-safe metal. This is because metal absorbs heat from the oven more rapidly and effectively than glass since metal is a stronger heat conductor than glass.

However, because glass is a poor conductor of heat, it takes longer for the food to cook and the heat to be absorbed. The glass cools down more quickly than the metal when the heat is gone.

The sample of oxygen will occupy approximately 18.5 mL at -70 °C and the same pressure.

The force exerted by a gas on specific area is known as gas pressure..

As we know, (P₁ V₁) /(T₁) = (P₂V₂) /(T₂)

Given, P₁ is the initial pressure (452 torr); V₁ is initial volume (32.2 mL)

T₁ is initial temperature in Kelvin (30 °C + 273.15 = 303.15 K)

P₂ is final pressure (452 torr); V₂ is final volume (what we want to find)

T₂ is the final temperature in Kelvin (-70 °C + 273.15 = 203.15 K)

Answer:

The volume of \(7.2\times 10^{-4}\ m^3\) is equal to 720 cm³.

Explanation:

We know that,

1 m = 100 cm

We need to convert \(7.2\times 10^{-4}\ m^3\) to cm³.

Also,

1 m³ = 10⁶ cm³

To convert  \(7.2\times 10^{-4}\ m^3\) to cm³, the step is as follows :

\(7.2\times 10^{-4}\ m^3=(7.2\times 10^{-4}\times 10^6 )cm^3\\\\=720\ cm^3\)

So, \(7.2\times 10^{-4}\ m^3\) is equal to 720 cm³.

By using Faraday's law of electrolysis, the number of moles of silver in the solution can be determined. From there, the molar mass of the silver salt can be calculated, allowing us to identify the silver salt and its formula.

Faraday's law of electrolysis relates the amount of substance deposited or liberated during electrolysis to the electric current passed through the solution. According to Faraday's law, the amount of substance (in moles) deposited is directly proportional to the product of the current (in amperes), time (in seconds), and the equivalent weight of the substance.

First, we calculate the number of moles of silver deposited:

moles of Ag = (current × time) / Faraday's constant

moles of Ag = (3.46 A × 704 s) / 96485 C/mol

Next, we can determine the molar mass of the silver salt:

molar mass of AgX = mass of AgX / moles of Ag

Given the mass of the silver salt (4.29 g) and the volume of water (520.0 mL), we can assume the density of water is 1 g/mL. Hence, the mass of the water is equal to its volume.

Finally, knowing the molar mass of AgX, we can identify the silver salt and its formula based on the molar mass and the periodic table.
