Answer:
The answer is A.
Explanation:
Gas particles do not have a fixed position or volume so they move in <em>r</em><em>a</em><em>n</em><em>d</em><em>o</em><em>m</em><em> </em><em>s</em><em>p</em><em>e</em><em>e</em><em>d</em><em> </em><em>a</em><em>n</em><em>d</em><em> </em><em>d</em><em>i</em><em>r</em><em>e</em><em>c</em><em>t</em><em>i</em><em>o</em><em>n</em><em>s</em>.

Answer:
SO42 - Trigonal planar ion
Explanation:
The SO4^2- ion is tetrahedral and not trigonal planar because the sulphur atom has four regions of electron density which includes the lone pair of electrons on sulphur atom.
This accounts for the observed tetrahedral arrangement of electron pairs around the central sulphur atom in SO4^2- ion, hence the answer.
Answer:
The amount of NaF produced is doubled.
(d) is correct option.
Explanation:
Given that,
A 2 mole sample of F₂ reacts with excess NaOH according to the equation.
The balance equation is
If the reaction is repeated with excess NaOH but with 1 mole of F₂
The balance equation is
Hence, The amount of NaF produced is doubled.
(d) is correct option.
