Q-3. * Because the perfumed incense is in solid state and by lighting of it‚ it changes from solid state to gaseous state the moment it turns in to gaseous state and gases have a property to spread in all directions. After lightening the incense the molecules of perfume are in a gaseous state and mixing with the molecules of air in the room. All of them undergo random motion at all times as a result of the internal ("heat") energy that they have absorbed. The molecules often bump into each other

CLASSIFICATION TESTS A. Acids There are relatively few suitable tests for carboxylic acids. Classification is based mostly upon solubility tests. If the compound is water soluble‚ test the aqueous solution of your compound with pH paper (also check the pH of the original water). If the compound is water-insoluble and it dissolves in 5% (1.5M) sodium hydroxide and 5% NaHCO3 solutions as performed in your solubility tests‚ it can be classified as a carboxylic acid. Establish an equivalence value

It is ‘thiazolidine-2‚4-dione’ and not thiohydantoins as the reaction product of monosubstituted thioureas and chloroacetylchloride a a a a a The reaction products of monosubstituted phenylthioureas with chloroacetylchloride in a polyethylene glycol (PEG-400) medium and K2 CO3 as base/catalyst at an elevated temperature are exclusively thiazolidine-2‚4-diones and not thiohydantoins as has been reported. The core unit thiazolidine-2‚4-dione is essentially derived from chloroacetylchloride

Chemistry Research Task The Periodic Table of Elements The Periodic Table of Elements is used as a way of displaying all the known chemical elements; it is accepted and used all over the world. The periodic table’s layout is very well structured; it consists of vertical rows called groups and horizontal rows called periods. It is one of the most important resources in chemistry and the key to discovering new elements. The beauty of the Periodic Table is that a lot of information about any

Peter Debye and his Contributions to Chemistry Abstract Dutch physicist Peter Debye studied under Arnold Sommerfeld‚ and developed several approaches using induced dipole moments and x-ray diffraction to study molecular structures. In 1912 he exhibited the Debye equation for dipole moments‚ a method to determine bond angles and the degree of polarity of covalent bonds‚ which allows the spatial configuration of molecules to be deduced with far greater accuracy than had previously
