Why is iron more reactive than copper? Why is corrosion only a problem for some metals (such as iron)? For making coins, why is zinc a good choice? What are some reasons why someone would choose zinc? Why are bridges not made from st...
Why do Potatoes produce Electricity? Why is zinc more reactive than copper? Why do fruits conduct electricity? Why do Metals conduct electricity? Why Do Circuit Breaks Trip? Why do cucumbers turn yellow? Help us improve. Please rate this article:...
Why is burning a chemical reaction? Why does water change state in the water cycle? Why is zinc not a transition metal? Why is the drying of wet clothes a physical change? Why does physical weathering speed up the processes of chemical weathering?
Its solid form is very explosive when shocked or heated to 275 degrees Celsius. In addition, it is very reactive with acids, chlorides, certain metals and their salts: Lead, Copper, Zinc, Cadmium, and Nickel. ... However, the hydrazoic acid generated when the sodium azide is dissolved is...
AZinc is less reactive than tin. BZinc acts as a preservative. CTin does not react with the components of food material. DTin lowers the ambient temperature, and thus, prevents spoilage of food.Submit Why teflon is used for making non-stick coating on cookwares? View Solution (a) Calcu...
What are the differences between the resolving and stacking gels? Why is it important that they are different? Why do whole grains and legumes actually inhibit zinc uptake by humans? What is the purpose of flaming an inoculating loop?
While previous results have suggested that zinc may be involved in limiting the formation of these highly reactive species, natural organic antioxidants such as vitamin E may also play an important role in reducing their effect. Recent results showing quantitative and qualitative differences in the ...
1. Understanding the Context: The question asks why electrolytic reduction is preferred over chemical reduction for isolating certain metals. To answer this, we need to consider the nature of the metals being extracted and the processes involved. 2. Identifying the Metals: More reactive metals, suc...
In the 1980s the cost of producing the penny grew to be higher than its face value so, in 1982 the composition of the penny was altered to have a core of zinc metal with a thin copper shell. The percentage of copper now allowed in the penny by Congress is 2.5% by mass. 1164 ...
