Answer: change
Explanation:
Change is change and sometimes it can be good and sometimes it can be bad.
We, know molecular mass of water is, M = 16 g/mol .
Given mass of water, m = 18 g.
We know, number of moles is given by :
Now, 1 mole of any compound contains 6.022 × 10²³ molecules.
So, number of moles in 1.125 moles of water is 1.125 × 6.022 × 10²³ =
6.77 × 10²³ molecules.
Hence, this is the required solution.
Because they have a full outer shell and they are both noble gases...Because the outer shell has attained stable electronics configuration of octate rule this it is with noble gas as helium.

Sulphur trioxide reacts with water to form a solution of sulphuric acid.
The equation describing this reaction is:
SO3 + H2O .............> H2SO4
Based on the above equation, the formula of the compound formed when sulphur trioxide reacts with water is: H2SO4
