This is an complete question, here is a complete question.
Consider the following standard reduction potentials in acid solution:



The weakest reducing agent listed above is:
(a)
(b)
(c) 
(d) 
Answer : The correct option is, (d) 
Explanation :
As we know that,
The substance having highest positive
potential will always get reduced and will undergo reduction reaction and weakest reducing agent or strongest oxidizing agent.
From the standard reduction potentials we conclude that,
having highest positive
potential than the other. So, it will always get reduced and will undergo reduction reaction and weakest reducing agent.
Hence, the correct option is, (d) 
<u>Answer:</u> The amount of hydrogen sulfide needed is 6.2 moles and amount of sulfur dioxide gas produced is 6.2 moles
<u>Explanation:</u>
We are given:
Moles of oxygen gas = 9.3 moles
The chemical equation for the reaction of oxygen gas and hydrogen sulfide follows:

<u>For hydrogen sulfide:</u>
By Stoichiometry of the reaction:
3 moles of oxygen gas reacts with 2 moles of hydrogen sulfide
So, 9.3 moles of oxygen gas will react with =
of hydrogen sulfide
<u>For sulfur dioxide:</u>
By Stoichiometry of the reaction:
3 moles of oxygen gas produces 2 moles of sulfur dioxide
So, 9.3 moles of oxygen gas will produce =
of sulfur dioxide
Hence, the amount of hydrogen sulfide needed is 6.2 moles and amount of sulfur dioxide gas produced is 6.2 moles
Answer:
i believe it is b as well
Explanation:
Answer:
A: Object A will move in the up direction. But not object B
Explanation:
It will move in the up direction because object A has an unbalanced force. For the up direction there, it is 6 newtons and for the bottom direction, it is 2 newtons. For the right and left direction, both of them are 3 newtons. So object A will move in the up direction because it has the most newtons(which is 6).
For Object B, it is unbalanced too. But object B will move to the right because it is 2 newtons there and there is one newton on the left. Furthermore, the up and down directions are 3 newtons. So they are balanced and will cancel out. Therefore, object A will move in the right direction because it has the most newtons(which is 3).
So the final answer is object A. Hope it helped!
