The potassium bromide, or KBr, has been used as an anti-seizure drug in human and veterinary medicine for over a century. Use uppercase for the first character in the element and lowercase for the second character. Balancing chemical equations. Balanced: AgNO3 + KI ----> KNO3 + AgI Is the equation not balanced? 2KBr(aq) + CaS(aq) -> K2S(aq) + CaBr2(aq). Given the long history of widespread use of both medications, neither is … Bromine is diaomic meaning it is naturalluy found as a molecule and therefore when properly balanced you get the answer above. the equation ive been given is; potassium bromide + sulphuric acid --> potassium hydrogen sulphate + Bromine + Sulphur dioxide + water it looks something like this i think but i cant balance it: KBr + H2SO4 --> KHSO4 + Br2 + SO2 + H2O I input this answer into the online hw, but it keeps telling me I am wrong. Home Reactions Blog. I am just supposed to write the molecular equation and whatever the precipitate is that has formed,if any. What is the balanced equation for silver nitrate and potassium iodide? Replace immutable groups in compounds to avoid ambiguity. Language: ru es en. Potassium + Bromine = Potassium Bromide 2K (s) + Br2 (g) = 2KBr (s) This is the balanced equation. Potassium bromide react with sulfuric acid. Examples: Fe, Au, Co, Br, C, O, N, F. Ionic charges are not yet supported and will be ignored. 2KBr + 3H 2 SO 4 2KHSO 4 + Br 2 + SO 2 + 2H 2 O [ Check the balance ] Potassium bromide react with sulfuric acid to produce potassium bisulfate, bromine, sulfur dioxide and water. Phenobarbital, or PB, has been used to treat seizures for years too. Log in: Chemical reactions Сhemical tables. They undergo a displacement reaction where a more reactive halogen in this case bromine displaces an iodide from its salt. I have got this so far, but I am kind of stuck what is wrong with my equation. The balanced equation will appear above. Bromine and Potassium iodide react to form Potassium bromide and Iodine. To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. Potassium bromide - solid.
