Chemicals Question 1



Leathersofa: carbon monoxide, ammonia, ketones, hydrogen cyanide, nitriles,nitriles, and aliphatic amines.

Computerdesk: carbon IV oxide

Polyurethane-basedpaint: carbon dioxide, traces of hydrogen cyanide and nitrogen oxides(Shriver, 2009)


Reactionbetween nitric acid and sodium hydroxide to give out sodium nitrateand water

HNO3+ NaOH —&gt NaNO3+ H2O

Reactionbetween ephedrine and water to give out

C10H15ON↔C10H16ON++ OH

Iodine: should be used in small quantities, one should wear eye protectionand gloves when handling it since it is an irritant. Keep a bottle ofsodium thiosulfate solution when handling iodine since it can be usedto treat any spill of iodine and reduce it to a harmless status.

Sodiumhydroxide: put on gloves, masks, and suitable dress to prevent anyharmful contact with the skin it can cause skin burns andirritation. Never touch any part of your skin or face when usingsodium hydroxide

Nitricacid: any reaction using nitric acid should be carried out inside acertified chemical fume hood. Hood of organics, flammables, and amongother incompatible substances should be cleared (Shriver, 2009). Inaddition, people working with this chemical should wear chemicalgoggles plus a face shield. Again, users should put on a chemicalsplash apron and a lab coat when handling nitric acid.

Ephedrine:it should be stored in a closed container since it extremely volatileeven at room temperatures. It should not be kept in contact withwater since it readily dissolves in it.

Whitegas fuel: people should be extremely careful when handling white gasfuel since it burn very fast and vaporizes very quickly.


Hazardsof chlorine:

Ithas several pulmonary irritant properties

Chlorinethat is used as a disinfectant in swimming pools is widely recognizedas a health hazard. This is because Shriver (2009) findings show thatchildren who often swim in chlorinated pools have a high likelihoodof developing asthma or allergies. Again, adults who have beenexposed to such pools have a high likelihood of developing heathproblems like rectal and bladder cancer.

Itreadily reacts with flammable materials since it is a strongoxidizer. For instance, it can react with iron creating achlorine-iron fire, which is a risk in chemical process plants.

Chlorinecan effectively be neutralized by reacting it with sodiumthiosulfate, which reacts with hypochlorite in the bleach to formchloride that is afterwards oxidized to sulfate.


Hazardousmaterials refer to any substance or object that pose a threat to aperson’s health and to the environment (Shriver, 2009). They can becorrosive, gaseous, radioactive, explosive, combustive, flammable orleachable.

Ihave learnt various ways of reusing and recycling potentiallyhazardous materials within my environment. For instance, acetone caneasily be recovered from spent solvents. Again, batteries can berecycled and zinc can be gathered from smelting furnaces. Likewise,refrigerators compressors, hydraulic fluids and used oil can be takenfrom fridges and cars for recycling purpose.
