Answer:
Hydrogen (H₂) gas at the cathode and Bromine (Br₂) gas at the anode
Explanation:
Bromine gas is evolved at anode.Since bromide ion is negatively charged it will go to anode to be oxidized and lose electrons.
while, Hydrogen gas is evolved at cathode .Since hydrogen ion is positively charged it will go to cathode reduced and gain electrons.
C. Beryllium. Which has 112 pm
X is the chemical symbol of the element
Solution :
In the process to isolate gold that has a 80 percent yield, a 3.00 g of Au is being isolated.
That is, the actual yield of Au is 3. 00 g
Therefore, we need to find the theoretical yield.
As we know,


As actual yield = 3.00 g
percent yield = 80 %
So, theoretical yield = 
= 3.75 g
Thus he should be able to get 3.75 g which is the theoretical yield of Au.
