(d) Ca(HCO3)2, (e) aluminum sulfide, (f) iron(III) sulfate, (g) disilicon hexabromide.
(a) mass, in grams, of 1.906 × 10−2 mol Bal2
[n = integer]
Chemical change involves a reorganization of the atoms in one or more substances.
The limiting reactant is the reactant that is consumed first,limiting the amounts of products formed.
