Give the names and charges of the cation and anion in each of the following compounds:. (a) CuS, (b) Ag2SO4, (c) Al(ClO3)3, (d) Co(OH)2 and (e) PbCO3

(a) : copper (II) sulfide or cupric sulfide.

(b)  : silver sulfate.

(c) : aluminum chlorate.

(d) : cobalt (II) hydroxide.

(e) : lead (II) carbonate.

Explanation:

Hello,

In this case, we proceed by exchanging the subscripts between the cation and anion for each case as follows:

(a) CuS: cation is cupper (II) and anion is sulfide, thus the name is copper (II) sulfide or cupric sulfide.

(b) Ag₂SO₄: cation is silver ion and anion is sulfate, thus the name is silver sulfate.

(c) Al(ClO₃)₃: cation is aluminum ion and anion is chlorate, thus the name is aluminum chlorate.

(d) Co(OH)₂: cation is cobalt (II) and anion is hydroxide, thus the name is cobalt (II) hydroxide.

(e) PbCO₃: cation is lead (II) and anion is carbonate, thus the name is lead (II) carbonate.

Regards.

the answer is 75.0%.

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
