If you know the molar masses of the reactants in a chemical reaction can you determine the molar masses of the products?
If you know know the molar masses of the reactants in a chemical reaction you can determine the molar masses of the products because the combined molar masses of the reactants equals the combined molar masses of the products.
Is 4Al 3O2 2Al2O3 exothermic or endothermic?
When aluminum burns, the reaction is highly exothermic.
Is the reaction agno3 plus fecl3 equals agcl plus fe no3 3 redox?
No, it is not a redox reaction. None of the oxidation numbers changes during the reaction. You have to determine the oxidation number for each element and see if it changes from reactant side to product side. If the oxidation number doesn't change, it is not a redox reaction.
