Why is electrical conductivity a resourceful property of metals like copper, silver, and aluminum?

Chemistry
1 answer:
aleksley [76]2 years ago
3 0

Answer:

The electrical conductivity of metals come from the fact that their outer electrons have been delocalised (meaning that the elections are not locked into atoms but can move freely throughout the metal ) .

And , the electrical conductivity of a metal is determined by the ease of movement of the electrons past the atoms<em> </em><em>under the influence of an electric field</em>.

46.6 grams of mercury II sulfate (HgSO4) reacts with an excess of sodium Chloride (NaCl). How many grams of mercury II chloride
slega [8]

Answer:

m_{HgCl_2}=42.7gHgCl_2

Explanation:

Hello,

In this case, the undergoing chemical reaction is:

HgSO_4+2NaCl\rightarrow HgCl_2+Na_2SO_4

In such a way, the mercury II sulfate (molar mass 296.65g/mol) is in a 1:1 molar ratio with the mercury II chloride (molar mass 271.52g/mol), for that reason the stoichiometry to find mass in grams of mercury II chloride turns out:

m_{HgCl_2}=46.6gHgSO_4*\frac{1molHgSO_4}{296.65 gHgSO_4}*\frac{1molHgCl_2}{1molHgSO_4} *\frac{271.52gHgCl_2}{1molHgCl_2} \\\\m_{HgCl_2}=42.7gHgCl_2

Best regards.
