Answer :
(a) The name of [tex]K_2Cr_2O_7[/tex] is, potassium dichromate.
(b) The name of [tex]Li_2C_2O_4[/tex] is, lithium oxalate.
(c) The name of [tex]CuNO_3[/tex] is, copper nitrate.
Explanation:
Ionic compound : It is a type of compound that is made up of the ions of the two different elements in which one element is a metal and another element is a non-metal.
(a) [tex]K_2Cr_2O_7[/tex]
The given compound [tex]K_2Cr_2O_7[/tex] is an ionic compound. It is made up of two different ions which are potassium ion [tex](K^+)[/tex] and dichromate ion [tex](Cr_2O_7^{2-})[/tex].
So, the name of [tex]K_2Cr_2O_7[/tex] is, potassium dichromate.
(b) [tex]Li_2C_2O_4[/tex]
The given compound [tex]Li_2C_2O_4[/tex] is an ionic compound. It is made up of two different ions which are lithium ion [tex](Li^+)[/tex] and oxalate ion [tex](C_2O_4^{2-})[/tex].
So, the name of [tex]Li_2C_2O_4[/tex] is, lithium oxalate.
(c) [tex]CuNO_3[/tex]
The given compound [tex]CuNO_3[/tex] is an ionic compound. It is made up of two different ions which are copper ion [tex](Cu^+)[/tex] and nitrate ion [tex](NO_3^{-})[/tex].
So, the name of [tex]CuNO_3[/tex] is, copper nitrate.
