Correct Answer: Option D i.e. 34.8 gReason:
Molecular weight of HgS = 232.66 g/mol
Atomic weight of Hg = 200.59 g/mol
Thus, 200.59 g Hg ≡ 232.66 g of HgS
Therefore, 30 g of Hg ≡
= 34.8 g
Thus,
34.8 g HgS would contain 30 g mass percent of Hg
22.6 x 10^5 J
‘Heat of vaporization’ is the amount of ‘heat’ required to convert '1g' of mass of a liquid to vapor. Normal “boiling point of water” is 100 C. The heat of vaporization at this temperature is 2260 J/g. It means 2260 J/g of heat is required to convert ‘1g of water’ to 1g of vapor at 100 C. So to convert 1 kg of mass of water or 1000g of water we require 22.6 x 10^5 J of heat.
Answer:When ethanol is oxidised with alkaline potassium permanganate (alkaline KMnO 4) or acidified potassium dichromate (acidified K 2 Cr 2 O 7), ethanoic acid is formed. Alkaline potassium permanganate and acidified potassium dichromate are strong oxidising agents, as they provide oxygen for oxidising other substances in the reaction
Explanation:
Answer: negatively charged; positively charged electrode.
Explanation:
Electrophoresis can de defined as the motion of dispersed particles relative to a fluid under the influence of a spatially uniform electric field. The electrophoresis of negatively charged particles is called anaphoresis while the electrophoresis of positively charged particles is called cataphoresis.
During proten electrophoresis, due to electric field, proteins migrate through pores in a polyacrylamide gel matrix. It must be noted that pore size decreases with increasing acrylamide concentration.
Proteins set up at a buffer pH of 8.6, the proteins will become negatively charged (that is, anions) and it will move to the positively charged electrode.
