Finish balancing the following equation: _Al(s) + 3Zn(NO3)2(aq) → __AI(NO3)3(aq) +_Zn(s) What coefficient does Al(NO3)3 have in the balanced equation? PLS HELP I WILL GIVE BRAINLIEST

Bis the answerhope it !

It is a mixture. simply put, a compound must be pure, that is, of only one chemical structure and composition. a mixture is made of different chemical substances (i.e. elements, molecules, compounds) that are not chemically bonded to each other, but instead physically grouped together, as in the case of gasoline (a homogeneous solution).

What are the activitys?   sorry if this took your points : (

In reversible reaction chemistry equilibrium is attained when the forward and reverse reactions are taking place at the same rate, thus, the concentrations of reactants and products remain the same. a reversible reaction is a chemical reaction where the reactants form products that, in turn, react together to give the reactants back. in irreversible reactions on the other hand, the reactants react to form the products, which cannot revert back into reactants.
