Question

i just wanna double check whether i answered correct or not please.

Why do we measure the volume of the flask in this experiment with water rather than using the volume listed on the side? Select all correct answers that apply. Must include all correct answers for full credit. The volume is not accurate on a flask to the number of significant figures required for this experiment The volumetric markings on the flask do not extend to it's full height so it is not possible to get an accurate volume using the volume listed on the side. The water will be displaced by CO2 in the experiment. D Question 5 0.5 pts Why is the flask not firmly stoppered during the sublimation step? Select all correct answers that apply. Must include all correct answers for full credit This is incorrect, the flask should be firmly stoppered during sublimation. The CO2 created during sublimation will be at higher pressure than the air outside skewing the results The pressure of the trapped CO2 gas could cause the stopper to spontaneously pop out of the flask.
