<h2>Answer : The order of conductivity from most conductive to least is this - </h2><h2>Calcium bromide
, Potsassium bromide (KBr), Benzoic acid
and last is sugar.</h2><h3>Explanation : </h3>
When dissolved in water produces three ions namely; 
and 
which acts as best conductor amongst the given choices.
Next is potassium bromide when dissolved in water generates only two ions which are 
and 
and acts as an conductor.
Benzoic acid 
, is a weak acid and is slightly ionized so it acts as an weak conductor.
Sugar is a non ionized compound so it is anon conductor.
Answer:
Galvanization or galvanizing is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are submerged in a bath of molten hot zinc.
Answer: The molarity of the solution is 2.00 M
Explanation:
Molarity is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute
= volume of solution in L = 1.00 L
moles of solute =
Thus the molarity of the solution is 2.00 M
The first one is abundant
