- Why should the selected rule(s) be followed? A residue left on the balance will contaminate the balance pan surface and anything that comes into contact with it afterwards. There may be discrepancies in accuracy between individual balances. Objects at any temperature other than room temperature can create air currents which can affect the balance pan, causing the measured mass to be higher or lower than the true mass. Weighing wet items will cause the displayed mass to be greater than the actual mass of the object.It is a type of mixture with particles evenly scattered in a dispersed medium without settling downPlease be a hundred percent sure that your answer is correct as there is no room for error
- Which of the following is not possible sources of error when weighing chemicals? Not waiting until samples in heated glassware have cooled to room temperature Weighing by directly placing chemicals on the balance without using a weighing boat Zeroing the balance before beginning Using more than one balance for a series of related weightingsWhat is the volume of the liquid based on the measurement shown in the following image? Choose the answer with the correct number of significant figures. ... 15 A 13.0 mL B) 13.00 mL 11.50 mL D 11.5 mLThis part of the analytical process is usually the most difficult step and the source of the greatest error.
