Answer:
Molten lead bromide, PbBr 2(l), is an electrolyte. During electrolysis: Pb 2+ ions gain electrons at the cathode and become Pb atoms. Br - ions lose electrons at the anode and become Br atoms, which pair up to form Br 2 molecules.

To answer this question, you need to know the chemical equation for making glucose. It should be look like this
C6H12O6<span>(s) + 6O2(g) -->6CO2(g) + 6H2O(g)
In the equation, the amount of glucose (</span>C6H12O6) is 1 and the amount of oxygen(O2) is 6. But the equation ratio is using moles as a unit. A mole of glucose will weight 180g but a mole of oxygen weight 32g.
Then, the amount of oxygen forms would be: 6/1 * (15.90g/180g) * 32g= 16.96 grams
Answer:
lower energy that helps the balance
