Inorganic

• concentration = mass / volume
• what does anhydrous mean

  a substance that contains no water of crystallisation
• Rate = change in absorbance / time
• Rate = volume of gas produced / time
• Rate = loss of mass / time
• Rate = H+ / time
• k = ln(2) / t1/2
• k = rate / (A)n
• ln(k) = ln(A) - Ea/RT
• pH = -log (H+)
• $(H^+) =$$10^-pH$
• Low pH = large (H+)
• high pH = small (H+)
• Strong acids completely dissociate so the concentration of the acid is equal to the concentration of H+
• original conc x diluting factor = new conc
• diluting factor = old vol/ new vol
• heat energy = mass of water x specific heat capacity of water x change in temperature
• Enthalpy change = (heat energy / 1000) / moles
• $q =$$mcΔT$
• mole fraction = number of moles of a substance / number of moles of all substances present
• partial pressure = total pressure x mole fraction
• total pressure = sum of all partial pressures
• $Kp =$$P(Products)^n \div P(Reactants)^n$
• new conc = ( original vol / new vol) x original conc
• $K =$$°C +$$273$
• $m^3 =$$dm^3 \div 1000$
• Pressure ( pascals) x Volume (m^3) = moles x 8.31 x temp (K)
• Ideal gas equation 


  $PV=$$nRT$
