Antimony Sb
Explanation:
The element that will have similar chemical properties with Arsenic As is element Antimony or Sb.
An element is a distinct substance that cannot be split-up into simpler substances. They are made up of only one kind of atom.
- The chemical properties of an element is determined mostly by the number of electrons in its outermost shell.
- This is called the valency of an element.
- Element having the same valency behaves the same way chemically.
- They exchange the same number of electrons during chemical reaction.
Therefore, elements in the same group on the periodic table have the same chemical properties.
Elements in the same group have the same valency.
Anitmony and Arsenic belongs to group 5 on the periodic table. The elements in this group are Phosphorus, Arsenic, Antimony and Bismuth.

Answer: C) 0.020 m
Explanation:
Molality of a solution is defined as the number of moles of solute dissolved per kg of the solvent.
where,
n = moles of solute
= weight of solvent in g
Mole fraction of 
is = 
i.e. moles of is present in 1 mole of solution.
Moles of solute 
=
moles of solvent (water) = 1 - = 0.99
weight of solvent =
Molality =
Thus approximate molality of in this solution is 0.020 m
