Answer:
Al is above H on the activity series
Explanation:
The given chemical reaction is expressed as:
2Al + 6HBr → 2AlBr₃ + 3H₂
The reaction above is a single displacement or replacement reaction and will only occur if Al is above H on the activity series.
- The driving mechanism of such reaction is the position of the species on the activity series.
- The higher an atom is the more reactive and easier it will displace the lower ones.
Explanation:
More is the mass of directly attached atom more will be the priority of the group attached to the alkyl or aryl chain.
Atomic mass of oxygen is 16, nitrogen is 14, carbon is 12, and hydrogen is 1.
This means that as the atomic mass of oxygen is greater than rest of the given atoms. So, priority will be given to the oxygen atom.
Thus, we can conclude that the given groups are placed in order of decreasing priority as follows.
-OH > > -COOH > -H
Answer:
The answer is option b.
Explanation:
Why? Because physicists and astronomers explore the dimensions of the universe… from the vastness of intergalactic space… to minute subatomic particles. They study the ways different forms of matter and energy interact.

Definitely definite mass because liquids can take on any shape and can have different volumes.
