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]

<em>List of metal or alloy that is best-suited include :</em>

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

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

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

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

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

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

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.

Anuta_ua [19.1K]

Answer:

2cm^3

Explanation:

Use the density triangle: D=MxV

Switch for variables, V=M/D

Plug in numbers, 15.8g/7.9g/cm^3=2cm^3

Why does bromine not react with sulphur?​
Zielflug [23.3K]

Answer:

The thermodynamic parameter which is of significance in this case is the 'Reduction Potential' for molecular bromine which is ~ +1.1 v vs N.H.E. In other words, it is a strong oxidizing agent. The bromine will oxidize sulfur compounds in which the valence of sulfur is lower than six to sulfate.

There are many possible reactions. Here is one possible example:

Na2 S2O3 + 4Br2 + 5 H2O = 2NaHSO4 + 8 HBr

How do you find the # of sigma and pi bonds using a Lewis dot structure
Lubov Fominskaja [6]

Every single bond is a sigma bond.

A double bond contains 1 sigma bond and 1 pi bond.

A triple bond contains 1 sigma bond and 2 pi bonds.


For example, in acetylene, H-C≡C-H, the sigma bond is formed by the head-on overlap of two sp orbitals. The pi bonds are formed by the side-on overlap of 2p orbitals.
