Question

1. list and explain 3 correct lab procedures shown in the illustrations. a. ____ b. __ c. ____

Explanation:

To answer this, we need the illustrations (images) showing the lab procedures. Since they aren't provided, here's a general guide for common correct lab procedures (assuming typical science lab scenarios like in Biology, Chemistry, or Physics labs):

a. Wearing Lab Coat and Safety Goggles

Lab coats protect clothing from chemicals/spills, and safety goggles shield eyes from splashes, fumes, or flying debris (e.g., during glassware handling or chemical reactions).

b. Proper Disposal of Chemical Waste

Separating and disposing of hazardous (e.g., corrosive, flammable) and non - hazardous waste in designated containers prevents environmental harm, chemical reactions, or safety risks (e.g., mixing incompatible chemicals in regular trash).

c. Using Pipettes with Pipette Aids (or Proper Technique)

For accurate volume measurement and to avoid direct contact with chemicals (which could harm skin or contaminate samples), using a pipette bulb/aid ensures controlled transfer of liquids (e.g., in titrations, solution preparation).

If you can share the illustrations (describe the actions shown), we can provide more specific explanations tailored to the depicted procedures.
