Average speed = (total distance covered) / (time to cover the distance)
Total distance = 69 km + 51 km = 120 km
Total time = 3 hrs + 2 hrs = 5 hrs
Average speed = (120 km) / (5 hrs) = 24 km/hr
From the balanced reaction, we are given that 1418 kJ of
heat is released for every 2 moles of nitromethane (CH3NO2) reacted.
So first calculate the moles of CH3NO2:
moles CH3NO2 = 5560 g / (61.04 g/mol)
moles CH3NO2 = 91.1 mol
So total heat released is:
total heat = (-1418 kJ / 2mol) * 91.1 mol
<span>total heat = -129,162.52 kJ = -129.16 MJ</span>
Answer : The magnitude of the orbital angular momentum for its most energetic electron is, 
Explanation :
The formula used for orbital angular momentum is:
where,
L = orbital angular momentum
l = Azimuthal quantum number
As we are given the electronic configuration of Fe is, ![[Ar]3d^64s^2](https://tex.z-dn.net/?f=%5BAr%5D3d%5E64s%5E2)
Its most energetic electron will be for 3d electrons.
The value of azimuthal quantum number(l) of d orbital is, 2
That means, l = 2
Now put all the given values in the above formula, we get:
Therefore, the magnitude of the orbital angular momentum for its most energetic electron is,
A.

Explanation:
The <em>electromagnetic spectrum</em> is the name given to the full range of frequencies and/or wavelengths that electromagnetic phenomena may have.
Human eyes respond to a small range of wavelengths in that spectrum. That response is called <em>sight</em>. Because humans can see that electromagnetic energy, it is called <em>visible light</em>.
