Copper and tin are completely soluble in each other. Explain why the yield strength varies with alloy composition as shown below. What are the basic steps in the preparation of the welding surface? Explain thermoset polymers and types of Thermosets?
Discuss the main difference when recrystallizing phenacetin vs. acetanilide from water. Would there be any difference and why? Explain diamagnetism and paramagnetism. Explain the difference between a promoter, silencer and enhancer. Describe in detail the difference between a substitutional alloy and...
Explain why copper possesses a high electrical conductivity. Why do metals tend to be malleable? Explain the elasticity of metals using the Fe-C alloy as an example. Why does steel not react with either strong or weak acids? Is it because it's an alloy? Explain. ...
Explain why hydrogen fluoride (HF) has a higher boiling temperature than hydrogen chloride (HCl) (19.4{eq}^o{/eq}C vs. - 85{eq}^o{/eq}C), even though HF has a lower molecular weight Van Der Waals Forces: Van Der Waa...
Alloys such as brass and bronze can be plated too, by arranging for the electrolyte to contain salts of all the metals that need to be present in the alloy.Electroplating is also used for making duplicates of printing plates in a process called electrotyping and for electroforming (an ...
This is sort-of why you’re not allowed to carry a mercury thermometer onto a (aluminum-bodied) airplane; the mercury wets the aluminum, and destructive oxidation generally follows. CamillaAnswered Jan 06 2022 When liquid water is confined in a tube, its surface (meniscus) has a concave shap...
Why does steel not react with either strong or weak acids? Is it because it's an alloy? Explain. Briefly describe three different methods for refining a metal. Explain the elasticity of metals using the Fe-C alloy as an example.
Metals are important in a variety of industries, technology, building, and everyday life, because of their flexibility, strength, and conductivity.Answer and Explanation: Silver is classified as a metal, specifically a transition metal. It has the following properties. Silver has a brigh...
Explain why covalently bonded materials are generally less dense than ionically or metallic bonded materials. Covalent Bonds: Covalently bonded materials have covalent bonds between their atoms. The covalent bonds are formed when electrons are shared by the atoms of ...
The phase of the alloy decides the properties of the alloy. The phase transformation is done by heating and cooling of the alloy so that the desired properties can be achieved by changing the phase.Answer and Explanation: Coarse pearlite: this is fo...
