Answer:

Metallurgy is the correct answer.

Explanation:

Metallurgy is the branch of science which deal with the studies of physical and chemical properties of metals, its uses, and the production of metals.

It helps to know the physical and chemical behavior of metals.

Thus we can conclude that the study of the isolation, structure, properties, and uses of metals are called Metallurgy.

The answer is; metallurgy

Metallurgy is a component of material science and engineering. This knowledge is also used to refine metals from their ores. The study of the physical nature of metals is called physical metallurgy while the study of the chemical nature of the metals is called chemical metallurgy.

A gas at constant volume has a pressure of 4. 50 atm at 200. K. What will be the pressure of the gas at 250. K? 3. 60 atm 4. 60

Trava [24]

5.625 atm will be the pressure of the gas at 250 K temperature of the gas at constant volume.

<h3>How we calculate the pressure of the gas?</h3>

Pressure of the gas will be calculated by using the ideal gas equation as:

PV = nRT,

From the question, it is clear that:

Moles of the gas and volume is constant here, so we calculate the pressure by rearranging the above equation as:

P/T = nR/V

And required equation will be:

P₁/T₁ = P₂/T₂, where

P₁ = pressure of gas = 4.50 atm

T₁ = temperature of gas = 200 K

P₂ = pressure of gas = to find?

T₂ = temperature of gas = 250 K

On putting all these values in the above equation, we get

P₂ = 4.50 × 250 / 200 = 5.625 atm

Hence, 5.625 atm is the pressure of the gas.

An aluminum atom possesses three valence electrons. Which is most likely to occur for an aluminum atom to obtain a complete vale

irina1246 [14]

The atom will lose three valence electrons.

<h3>What is meant by valence electron ?</h3>

A valence electron is an electron that is part of an atom's outer shell in chemistry and physics. If the outer shell is open, the valence electron can take part in the creation of a chemical bond.
Each atom in the bond contributes one valence electron to create a shared pair in a single covalent bond.
The chemical properties of an element, such as its valence—whether it can bond with other elements and, if so, how readily and with how many—can be affected by the presence of valence electrons. In this way, the electronic configuration of an element greatly influences its reactivity.
A valence electron for a main-group element can only be found in the outermost electron shell; for a transition metal, it can also be found in an inner shell.
