Hydro example sentences

Natural vegetation and wildlife exist only in the narrow zone of contact between the lithosphere, hydrosphere and atmosphere that we call biosphere.But carbon compounds, except for oxides of carbon, carbonate and hydrogencarbonate salts continue to be studied under organic chemistry.The remaining sp hybridised orbital of each carbon atom undergoes overlapping along the internuclear axis with the 1s orbital of each of the two hydrogen atoms forming two C-H sigma bonds.The number of hydrogen atoms is still less in alkynes as compared to alkenes or alkanes.They react with ethyne to form sodium acetylide with the liberation of dihydrogen gas.The basic solution is formed due to the presence of hydroxyl ions.You will study about types of bonds formed between atoms in Chapters 3 and Calcium oxide reacts vigorously with water to produce slaked lime (calcium hydroxide) releasing a large amount of heat.Hydrolysis of dimethyldichlorosilane, (CH3)2SiCl2 followed by condensation polymerisation yields straight chain polymers.All water moves within the hydrological cycle ensuring that water is a renewable resource.In this unit, you will learn more about hydrocarbons.One such conformation in which hydrogen atoms attached to two carbons are as closed together as possible is called eclipsed conformation and the other in which hydrogens are as far apart as possible is known as the staggered conformation.Why is it so ? Has it something to do with their structures and the hybridisation ? You have read that hydrogen atoms in ethyne are attached to the sp hybridised carbon atoms whereas they are attached to sp2 hybridised carbon atoms in ethene and sp3 hybridised carbons in ethane.Alkenes are unsaturated hydrocarbons containing at least one double bond.Methane reacts with steam at 1273 K in the presence of nickel catalyst to form carbon monoxide and dihydrogen.In a series of experiments, Haber started with known amounts of dinitrogen and dihydrogen maintained at high temperature and pressure and at regular intervals determined the amount of ammonia present.
