Use the items in the space to construct a flow chart for the procedure you will use to titrate the saturated borax solutions prepared at different temperatures during the Enthalpy and Entropy of a Borax Solution laboratory. Step 1. Create 250 mL of 0.500 M HClHCl from a 5.185.18 M stock solution. How many milliliters of stock solution will you use? volume of stock solution = mL Step 2. Set up the titration. Label the solutions that should be present in the buret and the Erlenmeyer flask.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
