Answer:
For every 4 moles of NO created, 6 moles of H2O are created so the ratio is 4:6
Explanation:
You just need to balance the equation.
NH3 + O2 -> NO + H2O
1. I started with hydrogen; there's 3 on the left and 2 on the right. Multiply them together to find a number they both go into (3×2=6, but in this case 6 hydrogen on each side does not work so I doubled it so there is 12 hydrogen on each side).
This will bring you to this:
4NH3 + O2 -> NO + 6H2O
2. Now get equal amounts of nitrogen on each side. There's 4 nitrogen on the left side, and 1 on the right. Multiply the right by 4. Then you will have this:
4NH3 + O2 -> 4NO + 6H2O
3. Last thing you need to do is have the same amount of oxygen on both sides. On the left you have 2 and on the right you have 10. Get the left to 10 by multiplying it by 5.
Balanced: 4NH3 + 5O2 -> 4NO + 6H2O
In word form, for every reaction between 4 moles of ammonia and 5 moles of oxygen, 4 moles of nitric oxide and 6 moles of water will be created.
I hope this helps!
<span>he ratio of the RMS velocities is 0.837
Now the RMS velocity is inversely proportional to the square root of the Mol Wt
So we have V1/V(N2) = sq rt (28/M1)
So [V1/V(N2)]^2 = 0.837^2 = 0.70 = 28/M1 from which M1 = 28/0.7 = 39.97 (Ar)</span>

guys can u solve my ques plz
Answer:
Paired = 12
Unpaired = 0
Explanation:
Magnesium is alkaline earth metal.
It is present in second group.
Its atomic number is 12 and atomic mass 24 amu.
Electronic configuration:
Mg₁₂ = 1s² 2s² 2p⁶ 3s²
It can seen from electronic configuration that all electrons are paired because s subshell have one orbital and it can accomodate two electrons. Each s subshells in magnesium have two electrons so these are filled and have paired electrons. While p subshell have three orbitals and can accomodate six electrons two by each orbital with opposite spin thus 2p is also filled and have paired electrons.
