Whats the rest of the question
Glacial acetic acid
It is not in liquid state at 10°C.
c cH3cooH it was correct
don't know dear Google will help you
Mercury and bromine both are present in liquid state at room temperature but mercury is metal and bromine is non-metal.
So, liquid non-metal at room temperature is bromine.
this is the answer please follow me
in general, salt (particularly nacl) will increase the rate of corrosion (rusting).
to understand why, consider metallic iron
rusts (oxidises) to iron(ii) oxide
in the presence of oxygen
corrosion (rust) is 'redox' reaction, means it involves reduction (of oxygen into hydroxide ions) and oxidation (of metallic iron to iron cations).
for any redox reaction to take place, electrons are transferred. in case, from the metallic iron loses electrons to oxygen. the presence of salt (or any electrolyte) in the water accelerates the reaction because it increases the conductivity of water, effectively increasing the concentration of ions in the water and so increasing the rate of oxidation (corrosion) of the metal.
the situation is complicated by the fact that salt dissolved in water actually reduced the amount of dissolved oxygen present in the water. is because the water molecules are attracted to the dissolved ions from the salt (solvation), has the tendency to decrease the weak affinity of non-polar oxygen molecules to water, thereby driving dissolved oxygen out. so if the metal is totally submerged in water, salt concentrations can actually reduce the rate of corrosion, if the water is not aerated.
so it depends upon the amount of oxygen getting into the water and onto the metal. for example, underwater plants can release oxygen in salty water will accelerate the rate of corrosion of the submerged metal. of course, if the metal is not completely submerged in salt water but only partially submerged, or is affected by salt water 'spray', it will be still be exposed to oxygen and will rust faster.
rewrite your question
hope you can understand
