Answer:
The volume of NaOH used
Explanation:
The tip of the buret is part of its calibration. If this tip is not filled before taking the initial reading, <u>the volume of NaOH used at the end of the titration would be inaccurate. </u>
<em>In order to avoid this, the valve of the buret should be opened and the NaOH allowed to displace whatever air that might have been trapped at the tip before the initial buret reading is taken and the titration is carried out. </em>

Answer:
the coefficients in a chemical equation give the number of molecules (or atoms) involved in the reaction. In the example reaction, two molecules of hydrogen react with one molecule of oxygen and produce two molecules of water. Second: the coefficients give the number of moles of each substance involved in the reaction.
