Answer:
high ph -basic,low pH -acidic
Explanation:
hi I'm from India nice to meet you
Well in polymerization or in dehydration synthesis, the individual monomer molecules contain either H or OH attached to the end of their respective molecules. When they chemically compline together both the H and OH come off or break from their respective molecules and form water as a product. In place, a covalent bond is produced connecting the monomers together. In break down of polymers, with Water, the water molecule essentially disconnects the large molecule at the same place where it would have formed a covalent bond, and causes one of the monomers to bond to either a H and or OH. Separating the 2 compounds.
Answer:
in the fraction distillation method, two liquids such as benzene and toluene are produced from the mixture of benzene and toluene.
Explanation:
Fractional distillation is a technique used in the industries for the separation of two or more liquids from one another. In this process liquid is heated, those liquid has lower boiling point will change into vapor form and collect in the upper chamber of fractional distillation while the liquid having higher boiling point also evaporates after sometime and keep it in another chamber. In the mixture of benzene and toluene, the boiling point of benzene is lower so it evaporates earlier than toluene.
Answer : Linear
Explanation : Hydrogen Cyanide (HCN) when drwan in the Lewis diagram shows carbon atom at the center with no lone electron pairs.
The carbon and nitrogen atoms are bonded through a triple bond which counts as "one electron pair".
The molecule has two electron pairs in all and appears to be linear.
Also, according to the VSEPR theory; the electron clouds on atoms around the carbon will try to repel each other.
They will get pushed apart, which gives HCN molecule a linear molecular geometry or shape.
The bond angle that is developed will be 180 degrees since it has a linear molecular geometry of HCN. The hybridisation observed in this molecule is SP.
