Question

select all steps below that help you handle chemicals safely. using droppers to transfer small amounts of chemicals using tongs to move hot objects checking the test tubes for chips prior to using them washing your hands after you finish the lab select all the reasons for checking glassware for cracks or chips prior to use. chips or cracks will make your experiment take longer. you could cut yourself on glassware that has a chip. chips or cracks can make the glassware more likely to break during use. chips or cracks will change the outcome of the experiment.

Explanation:

Using droppers for small - amount chemical transfer reduces spillage and exposure risks. Tongs for hot objects prevent burns. Checking test - tubes for chips avoids glass breakage and injury. Washing hands after lab removes chemical residues. Chips or cracks in glassware can cause injury due to sharp edges and increase the likelihood of breakage during use. They generally don't make experiments take longer or change outcomes directly (unless they affect volume measurements in some very specific cases).

Answer:

Steps to handle chemicals safely: using droppers to transfer small amounts of chemicals, using tongs to move hot objects, checking the test tubes for chips prior to using them, washing your hands after you finish the lab
Reasons for checking glassware for cracks or chips: You could cut yourself on glassware that has a chip., Chips or cracks can make the glassware more likely to break during use.
