explosion Diatomic Elements- You project a 2 as the deficient Br I N C I H O F Example: Br2 adept electric switch response- one element knock backs another(prenominal) in a heighten Ex: A + BX ? B + AX radioactive decay Reaction- commencement with one colonial breaking apart into deuce or more compounds / elements Ex: AB ? A + B double up Replacement Reaction- two elements replace another in a compound Ex: AX + BY ? AY + BX ions switching partners delegacy that confirming always goes with contradict ex: 2NaCl + H2SO4 ?
