When the Constitution was first proposed, many people were concerned about the federal government become too powerful. A group known as the anti-federalists pushed for a way to legally set aside certain rights and powers to individual states.

This amendment was added to satisfy the anti-federalists who were concerned that the Constitution would grant the federal government unlimited power.

The Tenth Amendment states that all powers that are not specifically given to the federal government are reserved to individual states.

For neutral atoms, the periodic trends in atomic size can be described like this

Atomic size decreases when going from left to right across a period,
Atomic size increases when going from top to bottom down a group.

Let's use these trends to try and figure out which atom would have the largest radius.

If you look at elements that are located in the same group, potassium will have a larger atomic radius when compared with sodium. Likewise, bromine will have a larger atomic radius when compared with chlorine.

Now focus on potassium and bromine. Since potassium is located at the start of period 3, and bromine at the end of the same period, potassium will have a larger atomic radius than bromine, and thus the largest atomic radius of the four given atoms.

Ans.  Suppose the speed of boat in still water is x km/h and speed of stream is y km/h

Speedof boat in downstream = (x + y) km/h x+ y = 32 …(i) 

Speed of boat in upstream = (x – y) km/h

x – y = 28 …(ii)

Add. Eqs. (i) and (ii), we get 2x = 60

x = 30 km/h

All enzymes are proteins but all proteins are not enzymes since, enzymes are subset of proteins.
