Explanation:

Question 1:

To determine safety precautions for acetone, we analyze its hazards: eye/skin/nose/throat irritation, harmful if inhaled/swallowed, birth defects, and explosive vapor. So precautions include wearing safety goggles, gloves, and a lab coat; working in a well - ventilated area (fume hood) to avoid inhalation; keeping it away from open flames/sparks; and avoiding ingestion by not eating/drinking in the lab.

Washing lab glassware after each use is important for several reasons. Residues from previous experiments can contaminate new experiments, leading to inaccurate results. Also, some chemicals can corrode or damage the glassware over time if left, and clean glassware is necessary for proper measurement (e.g., in volumetric glassware, residues can affect volume readings).

Answer:

• Wear appropriate personal protective equipment (PPE) like safety goggles, gloves, and a lab coat.
• Work in a well - ventilated area (preferably a fume hood) to minimize inhalation of vapors.
• Keep acetone away from open flames, sparks, and other ignition sources as its vapor is explosive.
• Avoid ingesting acetone by not eating, drinking, or smoking in the area where acetone is being used.
• Wash hands thoroughly after handling acetone to prevent skin irritation and accidental ingestion.
