The average melting point for a solid is -38.83 degrees Celsius and -37.89 degrees Fahrenheit.<span />
The atoms in the second to last group
The correct answer is 92. <span> uranium atom has 92 protons and 92 electrons. hope this helped, have an amazing day :)</span>
Answer:
Mass of NO produced is "6.5 g".
Explanation:
The given reaction is:
⇒ ![3 NO_2(g) + H_2O(l) \rightarrow 2 HNO_3(g) + NO(g)](https://tex.z-dn.net/?f=3%20NO_2%28g%29%20%2B%20H_2O%28l%29%20%5Crightarrow%20%202%20HNO_3%28g%29%20%2B%20NO%28g%29)
Now,
⇒ ![Moles \ of \ NO_2= \frac{Mass \ of \ NO_2}{Molar \ mass}](https://tex.z-dn.net/?f=Moles%20%5C%20of%20%5C%20NO_2%3D%20%5Cfrac%7BMass%20%5C%20of%20%5C%20NO_2%7D%7BMolar%20%5C%20mass%7D)
⇒ ![=\frac{30 \ g}{46 \ g \ mol^{-1}}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B30%20%5C%20g%7D%7B46%20%5C%20g%20%5C%20mol%5E%7B-1%7D%7D)
⇒ ![=0.65 \ mol](https://tex.z-dn.net/?f=%3D0.65%20%5C%20mol)
- We shouldn't have to acknowledge the sum of H₂O as it would be in excess. It's going to mot finish resolving answer.
- We provided 0.65 mol of NO₂, of which 3 mol of NO₂ = 1 mol of NO was previously given.
Accordingly,
is created.
So,
The mass of NO will be:
= ![mol\times molar \ mass](https://tex.z-dn.net/?f=mol%5Ctimes%20molar%20%5C%20mass)
= ![\frac{1}{3}\times 65 \ mol\times 30 \ g \ mol^{-1}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%5Ctimes%2065%20%5C%20mol%5Ctimes%2030%20%5C%20g%20%5C%20mol%5E%7B-1%7D)
= ![6.5 \ g](https://tex.z-dn.net/?f=6.5%20%5C%20g)
