A. The bubbles are lighter than air.
B. There is matter that cannot be seen inside the bubbles.
C. The bubbles will burst before long.
D. The bubbles cannot be broken into smaller pieces.
Common salt besides being used in kitchen can also be used as the raw material for making washing soda and baking soda.
The overall balanced reaction for washing soda preparation:
2NaCl + CaCO3 → Na2CO3 + CaCl2
NaCl is sodium chloride or common salt
Na2CO3 is sodium carbonate or washing soda
CaCO3 is calcium carbonate or limestone
The overall balanced reaction for baking soda preparation:
NaCl + CO2 + NH3 + H2O → NaHCO3 + NH4Cl
Baking soda (NaHCO₃ - sodium bicarbonate) is white, solid, crystalline salt or appears as a fine powder.
NH3 is ammonia
CO2 is carbon (II) oxide

The structure of tofacitinib with explicit carbon and hydrogen is the first attached picture.
The number of carbon atoms in tofacitinib are 16.
The molecular formula of tofacitinib is .
The structure of tofacitinib with all the filled hydrogen atoms is the second attached picture.
Answer:
2-iodo-2-methylpentane > 2-bromo-2-methylpentane > 2-chloro-2-methylpentane > 2-chloro-2-methylpentane
Explanation:
In this case, the<u> Sn1 reaction</u> would form a <u>carbocation</u>. So, the molecule that can generate a <u>very stable carbocation</u> will be more reactive. We have to remember that <u>tertiary carbocations</u> are the more stable ones. With this in mind, 3-chloropentane would be the <u>least reactive</u> molecules of all.
Then to decide which one is more reactive between the other ones, we have to check the <u>leaving group</u>. In this case, all the atoms are <u>halogens</u>, so if we have a <u>larger atom</u> the leaving group would leave <u>more easily</u>.
With his in mind the larger atom would be I, then Br and finally Cl, therefore the 2-iodo-2-methylpentane would be the <u>more reactive one.</u>
