Make sure the equation satisfies the law of conservation of matter.Write an equation expressing the fact that solid potassium and fluorine gas react to make solid potassium fluoride. Make sure the equation satisfies the law of conservation of matter....
Oxygen was discovered about 1772 by a Swedish chemist,Carl Wilhelm Scheele, who obtained it by heatingpotassium nitrate, mercuricoxide, and many other substances. An English chemist,Joseph Priestley, independently discovered oxygen in 1774 by the thermal decomposition of mercuric oxide and published his...

Ferric Nitrate + potassium thiocyanate = Iron (III) Thiocyanate + Potassium Nitrate Fe (NO3)3 + KSCN → Fe (SCN)+2 + KNO3 the one above i figure to be wrong because i can't balance it. calcium chloride + acetic acid + ammonium oxalate ...
A balanced chemical equation has an equal number of atoms of different elements in the reactants and products. For example, zinc reacts with dilute sulphuric acid to give zinc sulphate and hydrogen. This reaction can be written as \(\mathrm{Zn}+\mathrm{H}_{2} \mathrm{SO}_{4} \longri...
(Highly concentrated iodine is poisonous and may cause serious damage to skin and tissues.) For this reason, iodine is best weighed in a stoppered bottle; for the preparation of an aqueous solution, the bottle may contain a solution ofpotassiumiodide, which considerably decreases the vapor ...
