The name of cu+ is copper (i) ion. true false

The correct answer is True.

Explanation:

Copper is the 29th element of periodic table. It is a transition metal and shows a variable oxidation state of +1 and +2.

The oxidation state of transition metals is written in roman numbers after their elemental name. Thus, the ion is named as copper (I) ion.

Hence, the correct answer is True.

by the combination of an unlimited number of elements

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
