A chemical formula shows what elements a compound contains, and the ratio of the atoms or ions of the elements in the compound.
No. The formula unit for an ionic compound denotes the ratio of ions in the compound. For example, the formula unit NaCl indicates a ratio of 1 sodium ion to 1 chloride ion, CaCl2 indicates a ratio of 1 calcium ion to 2 chloride ions, and Fe2O3 indicates a ratio of 2 iron ions to 3 oxide ions.
The atomic ratio Sr/Br is 2.
KBr(solid) = K+(aq) and Br-(aq). (aqueous) means dissolved in Water.
