I need help with one of my pre-lab questions which I want to understand. Its question number 2, the one that highlighted. I don't want to make it over-complicated, I want something that I can understand.

Identify mitigating measure/s What should be the appropriate response to minimize harm During the pre-lab discussion, Mark dozed off. During the lab work, he mixed 2 chemicals and an explosive chemical reaction occured.

Please explain me this problems! Please don't reject this!! this is just HW problems.  I waited the solutions for more than 4 hours, but you guys just reject all the questions.. please..

Continued... 5. Answer ALL parts of this question The stability of chloramphenicol in eye drops is being studied at different temperatures and times. The concentration (in mg/L) of chloramphenicol at three different temperatures over time is provided below. Time (day) -18°C 25°C 40°C 25 28 23 7 27 20 20 30 20 21 20 180 23 25 19 (a) Using the data in the tables below assess and explain if the reaction time (after 1 hour of the start of the reaction) was an important factor affecting the yield of the reaction and provide the null hypothesis of the statistical test carried out. (b) The amount of chloramphenicol at -18 °C seems to vary with some values appearing to be higher than others. Explain what may be causing this variation AND suggest a methodology to identify if there was a systematic error in the measurement. ||
