What would happen to the amount of matter on earth if mass were not conserved during changes of state?
In chemistry, a precipitation reaction is a double replacement reaction. It involves two reactants and two products. It means that the cations and anions of the compounds interchange with one another to yield two products. But what makes precipitation reactions different is that when two liquid reactants are allowed to react together, a solid substance called precipitate is formed. The solid appears because it is insoluble to the other product in aqueous state.
Therefore, basing on the choices given, precipitation reactions apply to letters C and D.
Exocytosis : exo- means outside , -cyte means cell
<span>No. A chemical reaction does not destroy matter but it can convert matter into another form or into a substance with a different molecular structure. Matter can even be converted into energy in a nuclear reaction.</span>
