Explain the difference between SI base units and derived units Give an example of each?

Derived units are units built up from SI base units. It has been found that relatively few base units are required.
Typical derived units are m/sec (metres per second), sometimes written m.sec-1 for speed and joules/sec, sometimes written joules.sec-1 for power. Although the latter unit is a derived unit, it has its own name, the watt, for convenience. (Nonetheless, the people who govern the business of defining units have been scrupulous in defining it in terms of base units because it's possible.) New base units are defined when phenomena are encountered which simply cannot be measured in terms of existing base units or units derived from them.

∙ 9y agoA SI base unit is a direct measurement unit for a physical entity, an example of which is kilogram. A derived unit is determined by a physical equation with the base units, an example of which is meter per second.

∙ 13y agoThere are several SI base units, and many more derived units, which are combinations of other units. For example, meter and second are base units, meter/second (for speed or velocity) is a derived unit. For more details, see these links:

Is ICI covalent or ionic?
This completely depends on the compound it is forming. If the compound is NaCl for example, this is an example of ionic bonding (the difference between the larger electronegativity and higher electronegativity is above 1.9). If it's somthing like FCl for example, the bond is covalent (the difference between the larger electronegativity and higher electronegativity is below 1.9).

What is example difference between a base and an alkali?
The difference is not very big, even quite formally, I'd say.Alkali are hydroxidesBase is a substance capable of reaction with protons (H+ ions) donated by acids.So:All alkali's in solution are bases,but not all bases are alkali: for example NH3 basic but not a hydroxide of a metal ion.
What is the difference between fume and odor?

A neutral boundary is a geographic feature or line that separates two areas without favoring either side politically. For example, a river or mountain range can serve as a neutral boundary between two countries. A political boundary is a demarcation line established by governments to separate territories, often based on historical, cultural, or administrative factors. An example of a political boundary is the border between the United States and Mexico, which was established through treaties and agreements between the two countries.

Why is the answer in a math problem called the difference?
It's only called the difference if it is the answer to a subtraction. That is because that is the "difference" between the two numbers. For example: 5 - 2 = 3. 2 is 3 numbers away from 5. It's hard to explain, but hope I helped.
