Salt + Water Ex: HNO3 + NaOH ? NaNO3 + water N goes with N and H goes with H confirming always goes before forbid Combustion of Hydrocarbons Reaction- CxHy + O2 ? CO2 + H2O Ex: CH4 + O2 ? CO2 + H2O **When dealings hydrocarbons, it is always breathing out to be ?CO2 + H2O Reactions in Aqueous Solutions: last-place ionic equations- Ionic compounds (aqueous) = separate ions Ex: -NaCl (aq) Na(aq / positive) + Cl (aq / negative ) -Na2 SO4 2Na2 (positive) + SO4 (2- / negative) -Mg3(PO4)2 (aq) 3Mg (2+) + 2PO4 (3-) Terms: Soluble = in resultant Insoluble = solid state REVIEW: Nickel 28 electrons 4 efficiency levels hit the hay how to find sublevels and what they are to find valance board electrons highest energy level = 4 short cut on how to lay aside it when naming isotopes you have to put the physical body AND the indispensability number e x: Carbon -14 **check notes 14C protons! -6 elecrons-6 neutrons-8 7 go to bed how to name properties about an element.
