Hydro example sentences

Saturated hydrocarbons are fairly unreactive and are inert in the presence of most reagents.Soluble fluoride is often added to drinking water to bring its concentration upto 1 ppm or 1 mg dm– The F– ions make the enamel on teeth much harder by converting hydroxyapatite, [3(Ca3(PO4) Ca(OH)2], the enamel on the surface of the teeth, into much harder fluorapatite.Methane has a formula CH Hydrogen, as you know, has a valency of Carbon is tetravalent because it has four valence electrons.Elecctricity is generated mainly in two ways: by running water which drives hydro turbines to generate hydro electricity; and by burning other fuels such as coal, petroleum and natural gas to drive turbines to produce thermal power.The pH scale (pH = -log[H+]) for the hydrogen ion concentration (activity) has been introduced and extended to other quantities (pOH = – log[OH–]) ; pKa = –log[Ka] ; pKb = –log[Kb]; and pKw = –log[Kw] etc.Oxidation is the gain of oxygen or loss of hydrogen.Can you recall the structure of methane? According to SEPR theory (Unit 4), methane has a tetrahedral structure (Figureure 1 1) which is multiplanar, in which carbon atom lies at the centre and the four hydrogen atoms lie at the four corners of a regular tetrahedron.This method is used for industrial preparation of dihydrogen gas.Two of the pollutants that are emitted are hydrocarbons (unburnt fuels) and nitric oxide (NO).In this reaction, calcium oxide and water combine to form a single product, calcium hydroxide.All these fuels contain mixture of hydrocarbons, which are sources of energy.One or more hydrogen atoms of alkanes can be replaced by halogens, nitro group and sulphonic acid group.As mentioned earlier, in staggered form of ethane, the electron clouds of carbon-hydrogen bonds are as far apart as possible.Chlorine can replace the hydrogen atoms one by one.These days hydrogen peroxide (H2O2) is used for the purpose of bleaching clothes in the process of laundary, which gives better results and makes use of lesser amount of water.
