Molecule example sentences

Due to the maximum percentage of s character (50%), the sp hybridised orbitals of carbon atoms in ethyne molecules have highest electronegativity; hence, these attract the shared electron pair of the C-H bond of ethyne to a greater extent than that of the sp2 hybridised orbitals of carbon in ethene and the sp3 hybridised orbital of carbon in ethane.Eukaryotic cells and many prokaryotic cells, discussed in Chapter 5, need oxygen to break down glucose molecules and get energy for their activities.PS I has a 700 nm absorbing chlorophyll a P700 molecule at its reaction centre, while PS has a P680 reaction centre that absorbs red light at 680 nm.The single chlorophyll a molecule forms the reaction centre.How many carbon atoms would a molecule have which after accepting (fixing) CO2, would have 3 carbons (of PGA)? The studies very unexpectedly showed that the accepter molecule was a 5-carbon ketose sugar – it was ribulose bisphosphate (RuBP).Can you think of the general formula for alkane family or homologous series? The general formula for alkanes is CnH2n+2, where n stands for number of carbon atoms and 2n+2 for number of hydrogen atoms in the molecule.This process converts carbon dioxide from the atmosphere or dissolved in water into glucose molecules.The porous cellophane membrance of the tube allows the passage of molecules based on concentration gradient.For example, an aqueous solution of sodium chloride is comprised entirely of sodium ions and chloride ions, while that of acetic acid mainly contains unionized acetic acid molecules and only some acetate ions and protons.In the carbon fixation cycle, CO2 is added by the enzyme, RuBisCO, to a 5- carbon compound RuBP that is converted to 2 molecules of 3-carbon PGA.-Ray diffraction data reveals that benzene is a planar molecule.The soap molecules, thus form structures called micelles (see Figureure 12) where one end of the molecules is towards the oil droplet while the ionic-end faces outside.The steps involve utilisation of 2 molecules of ATP for phosphorylation and two of NADPH for reduction per CO2 molecule fixed.Can you now depict a molecule of water showing the nature of bonding between one oxygen atom and two hydrogen atoms? Does the molecule have single bonds or double bonds? What would happen in the case of a diatomic molecule of nitrogen? Nitrogen has the atomic number What would be its electronic configureuration and its combining capacity? In order to attain an octet, each nitrogen atom in a molecule of nitrogen contributes three electrons giving rise to three shared pairs of electrons.Before partition, if we were to pick up the gas molecules from left container, we would be sure that these will be molecules of gas A and similarly if we were to pick up the gas molecules from right container, we would be sure that these will be molecules of gas B.
