Cryolite, Na3AlF6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. Balance the equation for the synthesis of cryolite.

equation:
Al2O3(s)+NaOH(l)+HF(g)⟶Na3AlF6+H2O( g)

If 17.6 kg of Al2O3(s), 58.4 kg of NaOH(l), and 58.4 kg of HF(g) react completely, how many kilograms of cryolite will be produced?
mass of cryolite produced: kg Na3AlF6

Which reactants will be in excess?
-Al2O3Al2O3
-NaOHNaOH
-HFHF

What is the total mass of the excess reactants left over after the reaction is complete?
total mass of excess reactants: kg

Idid a lab for chemistry where we put nails in a copper (ii) chloride solution. 1. why did the reaction stop? which reactant was used up? how do you know? 2. describe what was happening to the atoms of iron and copper during the reaction. what is this type of reaction called? 3. what would happen to the ratio of copper to iron if you had placed more nails in the beaker? if you had let the reaction go for less time? 4. what is the accepted ratio of copper atoms to iron atoms in this reaction? account for differences between your experimental value and the accepted value. write the balanced equation for the reaction.
