Since non-metals (-ve ion) are "stronger" than metals (+ve ion), they may easily obtain electrons from metals. Ionic bonds are created when these two opposing ions are drawn to one another.

The term "metal" refers to any one of a group of materials with high thermal and electrical conductivities, as well as malleability, ductility, and high light reflection.

During the hippy era, when "heavy" indicated serious or profound, the term "metal" is thought to have originated. A few essential elements make up metal music: forceful drumming, extra-low bass notes, and angry or throaty vocals. The guitar riffs and chords are sometimes greatly distorted.

At Constant temperature, the behavior of a Ideal gas more closely approximates that of an ideal gas as its volume increases due to the average distance between the molecule becomes greater.

According to the Molecular Theory of gases, at constant temperature the behavior of a sample of a real gas more closely approximates that of an ideal gas as its volume is increased because the average distance between molecules becomes greater. The temperature did not change, so the average kinetic energy and average molecular speed did not change. The molecule size does not change either, so the molecule could not have expanded. The distance between the molecules increases causing a decrease in intermolecular forces, thus reducing the interaction between the molecules.

In a coordination complex, the number of unpaired electrons in the metal ion depends on the strength of the ligand field and the orientation of the ligands. Strong field ligands have a higher affinity for the d orbitals and can more effectively stabilize them, leading to a lower number of unpaired electrons in the metal ion.

Weak field ligands have a lower affinity for the d orbitals and do not stabilize them as effectively, leading to a higher number of unpaired electrons in the metal ion.

In a molecule with the formula AB2, the hybridization of the central atom is typically sp hybridization. This type of hybridization allows for the formation of two single bonds in opposite directions, which gives the molecule its linear molecular geometry.

A molecule with the formula AB2, such as carbon dioxide (CO2), is an example of a linear molecular geometry. In this type of molecule, the central atom is bonded to two other atoms, forming a straight line. The hybridization of the central atom, which is the process of mixing different types of atomic orbitals to form new hybrid orbitals, is determined by the number and types of bonds formed with the atoms around it.

In a molecule with the formula AB2, the hybridization of the central atom is typically sp hybridization. This is because there are two single bonds formed with two different atoms, which would require the combination of one s orbital and one p orbital. The s orbital is used to form the sigma bond between the central atom and the two other atoms, while the p orbital is used to form the two pi bonds.

To calculate the volume of Oxygen gas that would be required to produce a given amount of Fe2O3, we need to use the balanced chemical equation for the corrosion (rusting) of iron. The equation is:

3 O2 (g) + 4 Fe (s) —> 2 Fe,O3 (s)

This equation tells us that for every 3 molecules of Oxygen gas that react with 4 molecules of Iron, 2 molecules of Iron (III) oxide (Fe2O3) are produced. Since the atomic weight of Oxygen is 16.0 g/mol and the atomic weight of Iron is 56.0 g/mol, the molar ratio of Oxygen to Iron in the equation is 3/16 = 0.1875.

We can use this molar ratio to calculate the volume of Oxygen gas that would be required to produce a given amount of Fe2O3. To do this, we first need to convert the mass of Fe2O3 to moles. Since the atomic weight of Fe2O3 is 159.7 g/mol, 32.0 g of Fe2O3 is equivalent to 32.0 / 159.7 = 0.201 moles of Fe2O3.

We can then use the molar ratio of Oxygen to Iron to calculate the number of moles of Oxygen gas that would be required to produce 0.201 moles of Fe2O3. Since the molar ratio of Oxygen to Iron is 0.1875, 0.201 moles of Fe2O3 would require 0.201 * 0.1875 = 0.0376 moles of Oxygen gas.

Finally, we can use the molar volume of a gas at standard temperature and pressure (STP) to convert the number of moles of Oxygen gas to volume. At STP, one mole of a gas occupies a volume of 22.4 liters, so 0.0376 moles of Oxygen gas would occupy a volume of 0.0376 * 22.4 = 0

Answer:

The specific heat capacity of the metal is 0.529 J/g · C.

Explanation:

To calculate the specific heat capacity of a metal, you can use the following formula:

c = Q / (m * ΔT)

Where c is the specific heat capacity of the metal, Q is the amount of heat required to change the temperature of the metal, m is the mass of the metal sample, and ΔT is the change in temperature.

In your case, the amount of heat required to change the temperature of the metal is 481 J, the mass of the metal sample is 17.0 g, and the change in temperature is 67°C - 25°C = 42°C. Plugging these values into the formula, we get:

c = 481 J / (17.0 g * 42°C) = 0.529 J/g · C

Therefore, the specific heat capacity of the metal is 0.529 J/g · C.

The specific heat capacity can be calculated using the calorimetric equation. The specific heat capacity of the metal is calculated to be 0.67 J/ °C g.

The specific heat capacity of a substance is the heat energy required to rise its temperature by one degree celsius per one gram of the substance. It is an intensive property.

The calorimetric equation connecting the heat energy q to mass m, temperature difference ΔT and specific heat c is given below:

q = m c ΔT

Given mass = 17 g

heat energy q = 481 J

temperature difference = 67 - 25 = 42° C

Then c = 481 / (17 g × 42° C ) =  0.67 J/ °C g.

Therefore, the specific heat of the metal is  0.67 J/ °C g.

In order to create a crystalline lattice of alternate cations and anions from the blank ions, lattice energy is required.
