36) which pair represents two forms of an element in the same phase at stp but with different structures and different properties? a) i2(s) and i2(g) b) o2(g) and o3(g) c) h2(g) and hg(g) d) h2(s) and h2o()

The correct answer is option B.

Explanation:

Oxygen element exists in two forms:

1) Oxygen gas :

In this two oxygen atoms are bonded to each other with the help of double bond.

2) Ozone =

In ozone molecule, two oxygen are linked with double bond and the third oxygen atom is linked to one of the oxygen atom by accepting its lone pair of electrons. Due to this double bond resonates between the ozone molecule by which partial double bond character establishes between oxygen-oxygen bond.

idk i’m struggling too

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
