Perchloric acid (HCO₄) is one of strongest inorganic acids. Perchloric acid precipitation is used to removes most of the protein present in the
sample and stabilize many of the small molecule analytes. It can use also to precipitation glycogen, ATP, glutathione, antioxidants.
Perchloric acid donates protons to macromolecules and lower their solubility in water. Also perchloric acid is strong oxidizing agent and change oxidation number of elements.
Oxygen and carbon are element combinations that will most likely form polyatomic ions.
C) Condensation is the opposite of evaporation.
Condensation is the phase when water droplet form. Ex) When you have a glass of ice water the water droplets on the outside of the glass are condensation.
Evaporation is when a liquid heats up and turns into a steam or mist. Ex) When you boil water the steam that comes up from the pot is actually water!!
Therefore condensation is caused by cold temperatures, and evaporation is caused by hot temperatures.
