Coke is not preferred as a reducing agent in the reduction of the oxide of mercury to its metal, but is preferred in the reduction of the oxide of zinc to its metal. View Solution The electrolytic reduction process is used for alkali metals, because:- ...
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...
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...
ZincPolyunsaturated fatty acids (PUFAsChildhood cancerIt is proposed that the high normal concentration of docosahexaenoic acid (DHA) not only in the brain and retina, but also in the testis is an evolutionary adaptation helping to enhance the rate of electron flow through the respiratory chain in...
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 ...
You might have expected sodium metal to be deposited at the negative electrode. However,sodium is too reactive for this to happen so hydrogen is given off instead. hydrogen ions H+(aq) (from the water) are discharged at the negative electrode as hydrogen gas, H2(g) ...
