What is wrong with the name (in parentheses) for each of the following compounds: (a) BaCl2 (barium dichlo- ride), (b) Fe2O3 [iron(II) oxide], (c) CsNO2 (cesium nitrate), (d) Mg(HCO3)2 [magnesium(II) bicarbonate]

BaCl2-- Barium dichloride✔️, the dash (-) has the problem.

Fe2O3-- Iron(iii)oxide✔️, it's not Iron(ii)oxide.

CsNO2-- it's Cesium nitrogen dioxide✔️, not Cesium nitrate.

Mg(HCO3)2-- Magnesium hydrogen carbonate✔️, not magnesium(II) bicarbonate
