No. That could cause damage to the sink as well as the pipes. It could also create toxic gases that could kill you or others.

Explanation: I don't know if this helped but uh yeah.
Answer:
508.8g
Explanation:
Mass of one mole= (12×12)+(24×1)+(2×12)
144+24+24=192g
Mass of 2.65 moles=192×2.65=508.8g
Answer:
It will take 6.6 hours for 75% of the lead to decay.
Explanation:
The radioactive decay follows first order rate law
The half life and rate constant are related as
The rate law for first order reaction is
Where
A0 = initial concentration = 1 g
At= final concentration = 0.25 g (as 75% undergoes decay so 25% left]
