calorimetry

• what is the equation for calorimetry calculations?

  q=mc$\Delta$T
• what does everything stand for in q=mc$\Delta$T?


  q= energy required (J)

  m= mass (g)

  c= specific heat capacity (c)

  $\Delta$T= change in temp (K, celsius)
• what do you do after you find q?

  convert J to kJ

  divide by n to find $\Delta$H
• how to find $\Delta$rH?


  q=mc$\Delta$T

  m= total mass in g

  J$\rightarrow$kJ

  n= mol of limiting reactant

  q$\div$n
• how to find $\Delta$cH?


  q=mc$\Delta$T

  m= mass of water in g

  J$\rightarrow$kJ

  n= mol of fuel

  q$\div$n
• how to find $\Delta$neutH?


  q=mc$\Delta$T

  m=mass of total vol in g

  J$\rightarrow$kJ

  n= mol of $H_2O$

  q$\div$n
