The answer is A.
215K is equivalent to -58.15 °C and temperature corresponds with the average kinetic energy.
So the 15°C has a higher energy level than 215K.
There are many safety precautions and rules you MUST follow during labs.
for this incident here is what you should do:
1)Notify your Instructor and partner
2) if the liquid is toxic (like not water or vinegar) then let your Instructor handle it properly, or follow your instructors orders (like if they say to put a towel over it or something like that)
3) Broken glassware, minus mercury thermometer, must be immediately cleaned up, do not use your bare hand, always wear gloves.
4)dispose of the broken glass properly and clean the liquid up (unless it is harmful, then let your instructor do it)
It is false that if a question is asking about an opinion, it can be answered with science.
<h3>What is opinion?</h3>
A personal belief or assumed that is not tested or backed up by evidence is described as an opinion.
A hypothesis is typically a claim based on some form of observation or evidence. Hypotheses must be testable and, once tested, evidence-supported.
Any question that is based on opinion cannot be answered by scientific reasonings as it is not evidence based.
Thus, the given statement is false.

Answer:
1.8 x 10^ 24 atoms of oxygen
Explanation:
The molecular weight of ozone is known to be 48 grams / mol. Here we are given a sample of 48 grams of ozone as well, so in 48 grams of ozone the number of moles = 48 / 48 = 1,
_______________________________________________________
1 mole of ozone is equal to 6.0221415 × 10^23 molecules of ozone. Respectively, 1 molecule of ozone has 3 atoms of oxygen. Thus, you can conclude the following -
3 * 6.0221415 × 10^23 = ( About ) 1.8 x 10^ 24 atoms of oxygen
<u><em>Hope that helps!</em></u>
D= mass over volume
So, density equals 9.0g divided by 45ml.
SO, D=.25 g/ml
I'm not 100% sure this is correct, though. Best if luck. ♡
