Question

when should safety goggles be worn in a laboratory? (1 point)
when heating chemicals
while writing up lab reports
when using chipped glassware
for all experiments

Explanation:

To determine when safety goggles should be worn in a laboratory, we analyze each option:

• "when heating chemicals": While heating chemicals has risks, safety goggles aren't only for this; other experiments also need eye protection.
• "while writing up lab reports": Writing lab reports is a non - experimental, low - risk activity, so goggles aren't needed.
• "when using chipped glassware": Using chipped glassware is unsafe and should be avoided, and goggles alone don't address the main risk of using chipped glassware (like cuts), and also, goggles are needed for more than just this situation.
• "for all experiments": In a laboratory, any experiment can potentially involve hazards like chemical splashes, flying debris, or other risks to the eyes. So, to ensure eye safety, safety goggles should be worn for all experiments.

Answer:

D. for all experiments (assuming the options are labeled A - D in order, with "for all experiments" being the last option)
