Answer:
1. Beaker and Flask: These two volumetric devices are used to make coarse measurements of volume. These devices have graduated volume measurements marked on the side if the beaker and flask. The beaker and flask have a 5% accuracy.
2. Graduated Cylinder: More accurate than beakers and flask, with a 1% accuracy. Graduated cylinder are transparent with finely divided graduations. Their size vary from 5mL to 200mL.
3. Burets: These are cylindrical glassware with a valve at the bottom (commonly called a “stopcock”). They also have graduations on the side for accurate reading, and they have a 0.01mL accuracy.
4. Pipets: 12-24 inches long slender tubes, that measure predetermined volume. Mohr pipets are volumetric glassware pipets with graduations used to measure odd or fractional volumes to be provided. They have a 0.02mL accuracy. There are three types of pipets: air-displacements; positive-displacement; and the dispenser pipet.

<span>Answer:
Molecular:
HC2H3O2(aq) + KOH(aq) --> KC2H3O2(aq) + H2O(l)
Complete ionic:
HC2H3O2(aq) + K+(aq) + OH-(aq) --> K+(aq) + C2H3O2-(aq) + H2O(l)
Net Ionic:
HC2H3O2(aq) + OH-(aq) --> C2H3O2-(aq) + H2O(l)</span>
It is d as molecules move down the concentration gradient.Hope this helps
