Answer :electrostatic repulsion.
EXPLANATION
Valence shell electron pair repulsion theory, or VSEPR theory, is a model used in chemistry to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms
Not sure about 2 or 3 but I believe that for number 1 is B or claim 2!!
Answer: the effective nuclear charge of sulfur is less than that of chlorine
Explanation:
Ionization Energy can be defined as the energy needed for the complete removal of valence electron.
Ionization Energy decreases steadily down the group because of the outer electrons becomes progressively separated from the nucleus, hence they are less tightly held.
Also, Ionization Energy increases from left to right across the period i.e formation of a cation becomes more difficult owing to increase in nuclear charge.
Therefore, the effective nuclear charge of sulfur is less than that of chlorine because Chlorine have a greater ionization energy.
Answer:
Explanation: since oxalic acid is a weak acid it wont provide a strong acidic medium. So in order to provide a strong acidic medium dilute sulphuric acid is added.
