Answer:
The limiting reagents seemed to be those that were consumed first
.
Because when this reagent is consumed, the reaction stops. The quantity of this determines the total quantity of the product formed.
Explanation:
A limiting reagent is one that is consumed in its entirety. In this way, it delimits the amount of product that can be formed.
Take the case of two substances that interact and produce a chemical reaction. If one of the substances runs out as it is consumed during the process, the reaction will stop. The reagent consumed acts as a limiting reagent, that is, it limits the possibility of the reaction proceeding, and therefore it also limits the amount of the product generated by the reaction.
Answer: Gold act as cathode.
Explanation:
Standard potential for an electrochemical cell is given by:
= standard electrode potential =
The 
values have to be reduction potentials.
Reduction potentials for given elements
The element Be with negative reduction potential will lose electrons undergo oxidation and thus act as anode.The element Au with positive reduction potential will gain electrons undergo reduction and thus acts as cathode.
Cathode : 
Anode : 
Thus gold act as cathode.
Answer: Exothermic
Explanation: Looking at the graph, you see that the reaction started with more energy than it ended with, meaning it gave out its energy over the course of the reaction. This is also confirmed by the reaction equation, which shows the energy (891 kJ) on the right side of the equation.
