[@Ultapultasabkuch]

If there is no set limit for mercury exposure, then what is the 1mg/kg limit of mercury in skin lightening products as per minamata convention? Can't understand this point as I marked answer due to this fact only.

[@lifefung8710]

Mam hydrogen can not use direct in can

[@SleepyClassesIAS]

Can you share why not?

[@sdj9919]

Mam can you please elaborate the bio filters questions? How is the 1st option incorrect? If the uneaten fish food is converted to Ammonia, that would make the statement right?

Hfc are not used in lubricants. Please recheck. For hfc compressore we need mineral oil lubricants. They are not themselves used as lubricants

[@SleepyClassesIAS]

Let me check and I'll get back to you.

[@sdj9919]

I thought the same thing though Google says there are certain lubricants that use HFCs. Not sure though

15:06 ans is wrong

[@SleepyClassesIAS]

Can you please explain how?

[@yashs.9720]

I'm not well studied as you I had also gave same ans as you gave mam Lots of coaching gave wrong so i assume on majority....

[@shashiketan]

As much I have studied upsc pyq and their answer i am more than 100 percent sure it's C The statement is an absolute one so you have to prove it right in every situation to make it correct. If i treat carbon market as trading mechanism between private parties the statement immediately becomes false. (Answering based on my limited understanding)

IN FUEL cell WE USE WATER AND ELECTRODE NOT GRREN HYDROGEN, GREEN HYDROGEN IS PRODUCT OF ELECTROLYSIS

[@SleepyClassesIAS]

Yes it is. But is also used as a fuel in Hydrogen fuel cell Fuel cells work like batteries where hydrogen is fed to the anode, oxygen is fed to the cathode.

[@shashiketan]

13/19 too scared to check the whole answers but i think i did well in prelims 2023. I will just wait for the result. Question - there is no known safe level of mercury? i mean there has to be some number by some random organization? Minamata convention - we are preventing against mercury pollution so someone must have quantified it i guess?

[@SleepyClassesIAS]

Couldn't find it. The search is still on. I'll keep updated

[@spiritualsoldier1]

If mercury is so harmful then why doctor put thermometer which has mercury in the mouth?

[@SleepyClassesIAS]

Mercury spilled from broken thermometers also poses an environmental and safety risk.

[@SleepyClassesIAS]

Mercury spilled from broken thermometers also poses an environmental and safety risk. And that is why it is increasingly getting banned.
