Answer:
B.) +6
Explanation:
To find the oxidation number of sulfur, we can assume the oxidation numbers of the other elements.
What I mean is, oxygen (O) always has an oxidation number of (-2). That being said, if there are 4 oxygen atoms, oxygen is contributing -8 overall. We also know that hydrogen generally has an oxidation number of (+1). Like before, if there are 2 hydrogens, it must be contributing +2.
If the overall molecule is neutral, we have to get these charges to balance out.
In essence, -8 + 2 + ? = 0?
If you combine the charges from oxygen and hydrogen, you are left with -6. Therefore, to make the molecule neutral, sulfur must have an oxidation number of +6.
Answer:
613.0 g
Explanation:
2 L = 2000 mL
(30.65 g/100 mL)*2000 mL = 613.0 g
<span>Answer:
Correct answers are- Electron affinity decreases; Cl has 7 valence electrons but Na has only 1. So Na is going to lose its e, Cl is going to gain an e.</span>
