Answer:
Antoine Laurent Lavoisier (1743 -94), a French chemist was the first to establish an experimentally useful definition of an element. Elements can be normally divided into metals, non metals and metalloids.
Answer:
The answer to your question is: Flask X
Explanation:
Data
Flask X Flask B
Molar mass 30 g 60 g
mass 1.2g 1.2 g
Pressure 1 atm 0.5 atm
Formula PV = nRT
In the formula, we can notice that the number of moles (n)
is directly proportional to the pressure.
Then, let's calculate the number of moles
flask X flask Y
30 g --------------- 1 mol 60 g -------------- 1 mol
1.2 g ---------------- x 1.2 g ------------- x
x = (1.2 x 1) / 30 x = (1.2 x 1) / 60
x = 0.04 mol x = 0.02 mol
From the results, we conclude that the flask with the gas of molar mass 30g is the flask with pressure of 1 atm, because the higher the number of moles, the higher the pressure.
In general, the given alcohol above belongs to tertiary, and this is the reason why it doesn't undergo oxidation. Now, if you will try to analyze the given molecular formula, you will end up having seven (7) carbon atoms which make up a chiral carbon. So the answer would be option C. Hope that answer helps.
Answer:
The answer would be A to this question.
