Answer

Brief Explanations:

For the first question, oils from fingers or particles on gloves can contaminate a clean crucible, which can affect chemical reactions or analyses performed using it. For the second question, magnesium burns very brightly and the intense light can cause temporary blindness if proper eye - protection is not used.

Answer:

Question 1: You do not want to contaminate the crucible with oils on your fingers or particles on your gloves Question 2: Magnesium burns brightly enough to cause temporary blindness
