KBr(solid) = K+(aq) and Br-(aq). (aqueous) means dissolved in Water.
Magnesium Bromide
Potassium bromate
K2s
Cesium bromide. In a binary compound (2 constituent elements,) the non-metal becomes an "-ide" regardless of its normal name. So, oxygen becomes oxide, chlorine becomes chloride, nitrogen becomes nitride, etc...
The correct formula is K2Se. It is an ionic compound: potassium selenide.
Mercury (II) Bromide
Sodium Bromide
Magnesium Bromide
KMnO4
Potassium bromate
This compound is lead bromide - PbBr2.
The compound is Calcium Oxide and is commonly known as Quick Lime.
There is no compound k1 KI, with an uppercase letter "i" is potassium iodide
K2s
Cesium bromide. In a binary compound (2 constituent elements,) the non-metal becomes an "-ide" regardless of its normal name. So, oxygen becomes oxide, chlorine becomes chloride, nitrogen becomes nitride, etc...
More correct KCl is the formula unit of potassium chloride.
The correct formula is K2Se. It is an ionic compound: potassium selenide.
