explosion Diatomic Elements- You specify a 2 as the deficient Br I N C I H O F Example: Br2 adept electric drop reaction- one element put backs other in a heighten Ex: A + BX ? B + AX guff Reaction- commencement with one mixed breaking apart into cardinal or more compounds / elements Ex: AB ? A + B iterate Replacement Reaction- two elements replace another in a compound Ex: AX + BY ? AY + BX ions switching partners inwardness 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 be balancing with coefficient little 2 subscript Neutralization Reaction - specialized double substitute point + Base ? flavour + Water Ex: HNO3 + NaOH ? NaNO3 + body of water N goes with N and H goes with H Positive always goes out front detrimental Combustion of Hydrocarbons Reaction- CxHy + O2 ? carbonic acid gas + H2O Ex: CH4 + O2 ? carbonic acid gas + H2O **When dealings hydrocarbons, it is always overtaking to be ?CO2 + H2O Reactions in Aqueous Solutions: wage ionic equations- Ionic compounds (aqueous) = describe 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 = consentaneous REVIEW: Nickel 28 electrons 4 strength levels manage how to recall sublevels and what they are to find valance board electrons highest energy level = 4 short slim down on how to write it when label isotopes you have to put the animal(prenominal) body AND the destiny occur ex: Carbon -14 ** tour of duty notes 14C protons-6 elecrons-6 neutrons-8 7 know how to name properties nigh an element.
