Question

question 15 1 pts when you finish working with chemicals, biological specimens, and other lab substances, always treat your hands with skin lotion. wipe your hands on your clothes. wash your hand thoroughly with soap and water. wipe your hands on a towel. question 16 1 pts hot glass looks the same as cold glass.

Explanation:

When an acid is splashed on the skin, washing with plenty of water is a standard safety procedure to dilute and remove the acid. Weak bases can react with acids but may cause additional irritation if not properly neutralized. Soap is for general cleaning but not the first - line treatment for acid spills. Oil does not effectively remove acids.

After working with chemicals, biological specimens, etc., washing hands thoroughly with soap and water is a basic hygiene and safety practice to remove any residual substances. Treating with lotion is for skin care (not immediate cleaning), wiping on clothes or a towel does not remove contaminants properly.

Hot glass does look the same as cold glass, which is why one should not rely on visual inspection to determine if glassware is hot.

Answer:

For the first question: plenty of water.
For the second question: wash your hand thoroughly with soap and water.
For the third question: True.
