What is ionic compound?
A chemical compound known as an ionic compound in chemistry is one that contains ions held together by the electrostatic forces known as ionic bonding. Despite having both positively and negatively charged ions, or cations and anions, the compound is overall neutral. These can be either polyatomic species, like the ammonium (NH+ 4) and carbonate (CO2 3) ions in ammonium carbonate, or simple ions, like the sodium (Na+) as well as chloride (Cl) in sodium chloride. Since individual ions in an ionic compound typically have more than one nearest neighbour, they are not thought of as belonging to molecules but rather as components of an ongoing three-dimensional network. When solid, ionic compounds typically have crystalline structures.

Is the formation of iron rust endothermic or exothermic?.
The formation of iron rust is an exothermic process.
Rusting of iron refers to the formation of rust, which is a mixture of iron oxides, on the surface of iron objects or any other structures. This rust is formed from a redox reaction between oxygen and iron in the environment containing water such as air containing high levels of moisture. The rusting of iron is generally characterized by the formation of a layer of a red, flaky substance that easily crumbles into a powder after some time.
The rusting of iron is basically a gradual burning process. It is very exothermic in nature, however, due to the slowness of the process, the heat generated is lost before producing an actual temperature increase.
However, if the iron is dispersed in microscopic particles so that more of its surface comes into touch with oxygen, and the temperature is raised by rigorous friction at the same time, you can see genuine bright burning of iron.

What is heat ?The exchange of "thermal" energy brought on by a temperature differential is known as heat. Think of an isolated system with two subsystems that are initially operating at two distinct temperatures. The higher temperature subsystem 2 transfers energy to the lower temperature subsystem 1.The measured amount of energy is designated by the letter q. This process happens on its own, and we have all encountered its basic characteristics. The opposite process, which involves a spontaneous energy transfer between two subsystems that are initially at the same temperature and results in a difference in temperature, never happens.From the equation
qA + qB + qC + qD + qE = 0
we can solve to get
qE = -(qA + qB + qC + qD)
Reading through the problem , we can make the following variable assignment :
qA = -7 KJ
qB = 4 KJ

Considering the Boyle's law, if the temperature does not change, the new volume will be 6.25 L.
Boyle's lawThe gas laws are a set of chemical and physical laws that allow determining the behavior of gases in a closed system. The parameters evaluated in these laws are pressure, volume, temperature, and moles.
Boyle's law is one of the gas laws that relates the volume and pressure of a certain quantity of gas kept at constant temperature.
This law states that the pressure of a gas in a closed container is inversely proportional to the volume of the containert. That is, if the pressure increases, the volume decreases; while if the pressure decreases, the volume increases.
Mathematically, Boyle's law states that the product of pressure and volume is constant:
P×V= k
where P is the pressure and V the volume, being k a constant.
Studying two different states, an initial state 1 and a final state 2, it is satisfied:
P₁× V₁= P₂×V₂
New volumeIn this case, you know:
P₁= 1.25 atm V₁= 5 LP₂= 1 atmV₂= ?Replacing in Boyle's law:

The corresponding change in pressure in atm is 0.276 atm.
How does pressure work?Physical pressure applied to an object. Per unit area, a perpendicular force is delivered to the area of the objects. Pascals are a unit of pressure (Pa).
Briefing :
The change in pressure in the mercury barometer is given by ΔP = ρgh where
ρ = density of mercury = 13600 kg/m³,
g = acceleration due to gravity = 9.8 m/s² and
h = height of mercury = 21 cm = 0.21 m
So, ΔP = ρgh
= 13600 kg/m³ × 9.8 m/s² × 0.21 m
= 27988.8 kg/m-s²
= 27988.8 N/m²
= 27988.8 Pa
The change in pressure in atm
Since 1 atm = 101325 Pa
27988.8 Pa = 27988.8 Pa × 1 atm/101325 Pa
