D an average train goes 300 km/h or 190-220 mph
Answer:
Manganese decreases from 4+ to 2+ (reduced and oxidizing agent) and nitrogen increases from 2+ to 5+ (oxidized and reducing agent).
Explanation:
Hello there!
In this case, according to the given redox reaction, we rewrite it as a convenient first step:
![2NO + 3MnO_2 + 4H^+ \rightarrow 2NO_3^- + 3Mn^{2+} + 2H_2O](https://tex.z-dn.net/?f=2NO%20%2B%203MnO_2%20%2B%204H%5E%2B%20%5Crightarrow%202NO_3%5E-%20%2B%203Mn%5E%7B2%2B%7D%20%2B%202H_2O)
Next, we assign the oxidation numbers as follows:
![2N^{2+}O^{2-} + 3Mn^{4+}O^{-2}_2 + 4H^+ \rightarrow 2(N^{5+}O^{2-}_3)^- + 3Mn^{2+} + 2H^+_2O^{2-}](https://tex.z-dn.net/?f=2N%5E%7B2%2B%7DO%5E%7B2-%7D%20%2B%203Mn%5E%7B4%2B%7DO%5E%7B-2%7D_2%20%2B%204H%5E%2B%20%5Crightarrow%202%28N%5E%7B5%2B%7DO%5E%7B2-%7D_3%29%5E-%20%2B%203Mn%5E%7B2%2B%7D%20%2B%202H%5E%2B_2O%5E%7B2-%7D)
Thus, we can see that both manganese and nitrogen undergo a change in their oxidation number, the former decreases from 4+ to 2+ (reduced and oxidizing agent) and the latter increases from 2+ to 5+ (oxidized and reducing agent).

Flash drivers are more robust, if you drop it, it is still most likely to work. Hard drivers provide more storage. There’s not much difference
Answer:the temperature might increase because of the humidity in the room so everything gets goofy and moist

I’m sorry but where’s the worksheet lol......
