select from this list the one metal or alloy that is best suited for each of the following applications, and cite at least one r

Brut [27]

List of metal or alloy that is best-suited include :

1) Block of an internal combustion engine is made of grey cast iron because it is ductile and hard enough to bear the loads.

2) Steam heat exchanger is made up of stainless steel material as it has high resistance to corrosion and has the capacity to bear high-temperature differences.

3) For jet engine turbofan blades, titanium alloys are being used because they can able to bear high pressure and high energy loads.

4) Tool steel is used to make drill bit material as it has high tensile and point strength.

5) Aluminum alloys are used for cryogenic applications as it is the best suited for work at low temperatures.

6) Magnesium is used for pyrotechnics as it gives works on the effect of heat, light, and gas.

Alloy, a metallic substance composed of two or more elements, as both a compound or a solution. The components of alloys are ordinarily themselves metals, though carbon, a nonmetal, is an essential constituent of metal.

Alloys, in trendy, are more potent and harder, less malleable, much less ductile, and greater corrosion-resistant than the alloy's predominant metallic.

An alloy is created with the aid of mixing metallic with another issue, both any other metal or a nonmetal substance. Metallic alloys are commonly made by means of melting the substances, mixing them collectively, after which letting them cool to room temperature, ensuing in a strong material.

An electron in a hydrogen atom has orbital quantum number l = 7. how many possible values of the magnetic quantum number ml coul

MA_775_DIABLO [31]

A total of 15 magnetic quantum values are possible.

<h3>What is a Magnetic quantum number?</h3>

One of the four quantum numbers that describe an electron's position in relation to the nucleus is its magnetic quantum number.

Between spin and azimuthal quantum numbers, the magnetic quantum number comes in third on the list. The electron is positioned in one of the various orbitals formed by the division of the subshells (such as s, p, d, and f). It specifies the spatial direction of an orbital of certain energy (n) and form (I). The number of orbitals in each subshell is given as 2+1, where is the azimuthal quantum number. We can determine the orbital in each sub-shell using that method.

We are aware that there are between -l and +l conceivable magnetic quantum numbers.

Here l = 7

Thus, the range of magnetic quantum numbers will be -7 to +7.

Thus, the magnetic quantum numbers are as follows:

-7, -6, -5, -4,-3,-2,-1, 0, 1,2,3,4, 5, 6,7

This opens up a total of 15 magnetic quantum numbers.
