4 0

Answer: Option (4) is the correct answer.

Explanation:

In an O_{2} molecule there are two oxygen atoms and in a O_{3} molecule there are three oxygen atoms.

So, there will be different number of electrons involved in the bonding of atoms for both O_{2} and O_{3} molecules.

Therefore, both of them will have different structure and reactivity.

Thus, we can conclude that the statement they have different molecular structures and different properties, correctly describes two forms of oxygen, O2 and O3.

What is the solution to the problem to the correct number of significant figures (102,900/12)+(170•1.27)
GarryVolchara [31]

As per as the Multiplication rules of the significant figures, whenever any numbers in the decimals forms are multiplied or divided then result in mentioned in such a way so that the significant figures after the decimal will be same as that in the given least condition.


_______________________________


102900/12 = 8575


170 × 1.27 = 215.9


∴ (102,900 ÷ 12) + (170 × 1.27) =  8575 + 215.9


= 8790.9


Now, As per as Above rules, answer in correct significant figures will be = 8791.
