Introduction to Chemical Nomenclature and Bonding: A ComprehensiveAssignment1)Classify each of the following as a pure substance or a mixture. If it is a pure substance, is it anelement or a compound? Explain your answer.a.fluorine(used to make fluorides, such as those used in toothpaste)–pure substance-elementb. toothpaste-mixturedifferent elements are mixed in different proportionc.calcium fluoride, CaF2, from the naturally occurring ore fluorite(It isused to make sodiummonofluorophosphate, which is added to sometoothpastes.)-pure substance-compound2Write the chemical formula for each of the following compounds. List the symbols for theelements in the order that the elements are mentioned in the description.a.acompound with molecules that consist of two phosphorus atoms and five oxygen atoms.P2O5-phosphorus pentaoxideb.a compound with molecules that consist of two hydrogen atoms and one sulfur atom.H2S-hydrogen sulphidec.acompound that contains three calcium atoms for every two nitrogen atoms.Ca3N2-Calcium nitrided. a compound with molecules that consist of 12 carbon atoms, 22 hydrogen atoms, and 11oxygen atoms.C12H22O11-Sucrose3)Atoms of magnesium and oxygen form ions and ionic bonds in a similar way to atoms ofsodium and chlorine. The difference is that instead of having each atom gain or lose one electron,each atom of one of these elements loses two electrons, and each atom of the other element gainstwo electrons. Describe the process that leads to the formation of the ionic bond betweenmagnesium and oxygen atoms in magnesium oxide. Your answer should include mention of thecharges that form on the atoms.Mg(s)→mg2+(aq)+ 2e-O+2e-→O2-Mg+O→MgO4)How may protons and electrons do each of the following ions have?
