Write the correct equation and then balance the equation. silver nitrate + sodium bromide sodium nitrate + silver bromide

potassium iodide + lead (II) nitrate lead (II) iodide + potassium nitrate

iron (Ill) chloride + a mmonium hydroxide iron (IIl) hydroxide + ammonium chloride

what is the question here. i think you messed up.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
