The method used to separate oxygen from mercury oxide is by strong heating. In the lab mercury oxide is placed in strong glass test tube and strong heat applied to the test tube. Mercury oxide then undergoes a decomposition reaction to produce mecury and oxygen.
Antoine Lavoisier , the father of modern chemistry is the one credited as having proved the decomposition of mercuric oxide by heating, and that the result was production of mercury and oxygen.
A decomposition reaction is a reaction in which a compound breaks down into two or more simpler substances.
Answer
Manual samplers are prone to effects of temperature, speed of wind and air concentrations.
Explanation
Manual samplers face several challenges that can act as drawbacks to obtaining accurate results. They are subjected to effects of sampling duration where long sampling times are needed to obtain adequate mass for detection. Manual samplers face challenges when measuring non-volatile species because particles are observed into the adsorption medium at a slower rate of diffusion.
Condensation polymerization : releasing water as by product, occurs in monomer that has functional group that can react with each other e.g alcohol&carboxlic acid to form polyesters, carboxylic acid and amines to form polyamides,etc.
Radical Polymerization: occurs by propagating radical monomers or monomer that has unsaturated bonds, such as ethene, initiated by formation of radical from the monomer by using uv lights/other initiator, does not produce any by products
