Why are alloys produced? Why would magnesium remove tarnish from silver? Zinc reacts with diluted sulfuric acid to give hydrogen but silver doesn't. Explain. Why are most metals grey? If I was to put pure zinc into acetic acid, what would happen to the zinc? Why?
Why metals react more vigorously in acids than in water? Explain the role of electrolytes in promoting corrosion. Define the term hollow-cathode lamp used in chemistry. Why do we use metals in wires? (Select all that apply.) a. metals are lustrous b. metals a...
All commonly used types of industrial ovens are used for curing Teflon™ industrial coatings. Teflon™ coating systems are not affected by the combustion products of coal gas or natural gas, so direct fired gas ovens may be used. Both batch ovens and high production conveyorized ovens are ...
“The crude steel output cut will inevitably reduce the demand for manganese ore and manganese alloys,” a manganese ore trader source in China said. “But the manganese market still has its cushion for it,being listed as one of the critical mineralsand due to itsincreasingly diversified needs...

Copper also has superior alloying properties, it's... you know, when it's combined with other metals. 铜还具有优良的合金化性能,它……你知道,当它与其它金属结合的时候。 For instance, how many of you play a brass instrument, like a trumpet or a trombone?
In Roman times, gold salts were used to produce a distinctive red shade of glass known as ruby glass. Incredibly thin layers of gold less than a micron thick are used in modern windows to block heat from the sun. In energy production, gold nanoparticles have greatly increased the efficiency...
As it's too soft to practically use in jewellery, pure gold is often mixed (aka 'alloyed') with other metals to make it more durable. These gold alloys are
Identify the elements below as metals or non-metals. Calcium, silver. Elements in the s and p blocks of the periodic table are called? a. Alloys. b. Main group elements. Distinguish between an atom and an element. What does the atomic number of an el...
