Sulphur is an element belonging to group 16 and period 3 of the periodic table. Sulphur is a non-metal and is obtained as a byproduct after the production of natural gas. The most common form of sulphur is the yellow solid or powder form. Sulphur (S) is an element that can never be overlooked because […]

Carbon, as a member of group 14 of the periodic table, forms a range of compounds with oxygen known as carbon oxides. As a result, carbon oxides are pure carbon and oxygen organic molecules. Carbon monoxide (CO) and carbon dioxide (CO2) are the two carbon oxides that are most frequently encountered (CO2). On the other

Introduction Carbon dioxide is a chemical molecule that occurs naturally and plays an important part in the Earth’s environment.  It is required for photosynthesis, which is required for all plants to exist. Carbon dioxide also aids in the regulation of the planet’s and atmosphere’s temperatures.  They’re known as greenhouse gases because they let sunlight in

Introduction Chloroform is a colourless, sweet-smelling organic chemical compound with the formula CHCl3 and the IUPAC name trichloromethane. It is a thick liquid with C3 symmetry and tetrahedral molecular geometry. Chloroform is a very volatile liquid that, due to its narcotic qualities, has been frequently utilised throughout history. It has a reputation for anesthetizing or

The most crucial leavening ingredient in wafers & waffles, and usually the only one, is sodium bicarbonate. For soft, well-filled, & also well – formed wafers and waffles, the pH value rises, the flour acids are neutralised, and the batter distributed more evenly and easily in the hot baking mould. The browning is accelerated when the pH

Because of its low boiling point, propane gas has become a popular choice for barbecues and portable stoves. It vaporises as soon as it is released from and its pressurised and containers. Propane fuels buses, forklifts, taxis, outboard boat motors, and ice resurfacing machines, as well as recreational vehicles and campers for heat and cooking.

Halogenation is defined as the substitution of a halogen for one or more hydrogen atoms in an organic molecule (fluorine, chlorine, bromine or iodine). The halogenation of an alkane appears to be a straightforward substitution reaction in which a C-H bond is broken and a new C-X bond is generated, unlike the complicated changes of

Water and methane gas interact at temperatures below 10 degrees Celsius and pressures more than 30 bar, or 30 times normal atmospheric pressure, to form methane hydrate. The meth-ane is encased in a molecular cage and surrounded by water molecules. As a result, chemists refer to this type of molecular structure as a clathrate (lat.

The mechanism of selective oxidation of methane with hydrogen peroxide was studied for an H4PV1MO11O40 catalyst precursor, which has been reported to be the most active among various Keggin-type heteropolyacids and vanadium complexes in trifluoroacetic acid anhydride. The conversion vs. selectivity relationships, product reactivities with methane comparisons, and kinetic results all show that the first

Carbon dioxide is a naturally occurring chemical molecule that is necessary for the Earth’s ecosystem to function properly. It is necessary for photosynthesis, which is required for all plants to exist. Carbon dioxide also contributes to the regulation of the atmosphere’s and planet’s temperature. They are frequently referred to as greenhouse gases because they permit
