what uhm subject it didnt show for me :/ and im slow sooooo
Explanation:
State the problem that you are trying to solve. Make sure that the hypothesis clearly defines the topic and the focus of the experiment.
The answer is A. Voltaic cells couple oxidation and reduction half reactions to produce electromotive force from chemical potential energy. Electrolytic cells do the opposite in that they require electromotive force to store chemical energy.
Answer:- Theoretically 7.20 moles of are formed.
Solution:- The balanced equation for the reaction of Sulfur with nitric acid is---
From balanced equation, 1 mol of sulfur reacts with 6 moles of nitric acid. So, 1.20 moles of sulfur would react with 6 x 1.20 = 7.20 moles of nitric acid.
9.90 moles of nitric acid are available. It means nitric acid is present in excess and sulfur is limited. So, the theoretical yield is calculated by 1.20 moles of sulfur as...
1.20 mol x (6 mol nitrogen dioxide/1mol S) = 7.20 mol
