Process energy required
1) raise the temperature to 75.0 °C 628 J
2) evaporate the liquid at 75.0°C 15.6 KJ = 15,600 J
3) raise the temperature to ? 712 J
Total energy: 628 J + 15,600 J + 712 J = 16,940 J
As you must have realized the clue to do the problem correctly is to convert all the energy values to joules, because you cant not add up joules with kilo joules.
Answer: 16,940 J
Answer:
option A
![{1s}^{2} {2s}^{2} {2p}^{3}](https://tex.z-dn.net/?f=%20%7B1s%7D%5E%7B2%7D%20%20%7B2s%7D%5E%7B2%7D%20%20%7B2p%7D%5E%7B3%7D%20)
Explanation:
Atomic number of Nitrogen (N) = 7
So, no. of protons and electrons = 7
Then,
![1s {}^{2} {2s}^{2} {2p}^{3}](https://tex.z-dn.net/?f=1s%20%7B%7D%5E%7B2%7D%20%20%7B2s%7D%5E%7B2%7D%20%20%7B2p%7D%5E%7B3%7D%20)
Kinetic energy is proportional to the velocity squared, so increasing in velocity will have an exponentially greater affect on translational kinetic energy. if you doubled the mass of an object it will double only it’s kinetic energy, but doubling the velocity of the object will quadruple its velocity.
<span>These elements are red. They are typically gaseous at normal temperatures: some examples can include oxygen, hydrogen, and the noble gases (neon, argon, krypton). These elements all use the concept of STP (standard temperature and pressure) as their baseline: 1 atmosphere of pressure and 0 degrees Celsius.</span>
