The most stable isotope would be lead-82.
Answer:
heat must be supplied to the system at a rate of 6670.22 KJ/h
Explanation:
m = 8390 g/h * ( Kg / 1000g )
⇒ m = 8.39 Kg/h
P1 = P2 = 6,20 atm.......... constant pressure
T1 = 24°C = 297 K
T2 = 337.0°C = 610 K
⇒ ΔT = 610 - 297 = 313 K
Q = ?
starting from first law at constant pressure:
∴ Cp (24°C) = 2,54 KJ / Kg°K.......engineering toolbox CH3OH
⇒ Q = ( 8.39 Kg/h ) * ( 2.54 KJ / Kg K ) * ( 313 K )
⇒ Q = 6670.22 KJ/h
Answer:
True
Explanation:
Tighter particle compaction means less movement between particles for other substances to move through
permeable
(of a material or membrane) allowing liquids or gases to pass through it.
Answer:
Chlorine is found abundantly in earth crust and ocean.
Explanation:
The elements of group 17 are called halogens. These are six elements Fluorine, Chlorine, Bromine, Iodine, Astatine. Chlorine is one of them.
it is greenish-yellow irritating gas.
its melting point is 172.2 K
its boiling point is 238.6 K
It is present in earth crust and ocean abundantly.
In ocean chlorine is found in the form of salt sodium chloride.
About 1.9% mass of sea water consist of chlorine ions.
In earth crust it is present in minerals such as carnallite and sylvite.
it is disinfectant and can kill the bacteria.
it is also used in manufacturing of paper, paints and textile industries.
It is also reported that chlorine can effect the respiratory system, immune system and heart.
Up to some extent it can also effect the organism living in water.
