chemistry equations

• Chemistry equations - moles 


  Moles = mass/formula mass
• chemistry equations - concentration

  Concentration = mass/volume
• chemistry equations - concentration triple

  Concentration = moles/volume
• chemistry equations - % yield

  % yield = mass of product made/maximum theoretical mass of product
• chemistry equations - atom economy


  Atom economy = (formula mass of desired product/sum of formula mass of all reactants) x 100
• chemistry equations - moles

  moles = volume/24
• covalent bonds

  shared pair of electrons
• NaCl forms 


  An ionic lattice
