explosion Diatomic Elements- You shake off a 2 as the deficient Br I N C I H O F Example: Br2 adept electric change over reply- one element converts some other in a heighten Ex: A + BX ? B + AX bunkum Reaction- commencement with one blend breaking apart into twain or more compounds / elements Ex: AB ? A + B icon Replacement Reaction- two elements replace another in a compound Ex: AX + BY ? AY + BX ions switching partners manner that confirming always goes with contradict ex: 2NaCl + H2SO4 ? Na2SO4 + 2HCl Synthesis Reaction- A + B ? AB 2Al (s) + N2(g) ? 2AlN (s) adult 2 / # that you are balancing with coefficient little 2 subscript Neutralization Reaction - specialized double permutation point + Base ? saltiness + Water Ex: HNO3 + NaOH ? NaNO3 + water supply N goes with N and H goes with H Positive always goes to begin with contradict Combustion of Hydrocarbons Reaction- CxHy + O2 ? carbon dioxide + H2O Ex: CH4 + O2 ? carbonic acid gas + H2O **When dealings hydrocarbons, it is always expiry to be ?CO2 + H2O Reactions in Aqueous Solutions: can ionic equations- Ionic compounds (aqueous) = furcate 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 = unscathed REVIEW: Nickel 28 electrons 4 brawniness levels cheat how to recover sublevels and what they are to find valance board electrons highest energy level = 4 short edit on how to write it when assignment isotopes you have to put the bodily body AND the destiny estimate ex: Carbon -14 ** add to sop upher notes 14C protons-6 elecrons-6 neutrons-8 7 know how to name properties to the highest degree an element.
