Krypton is non metal it is part of the noble gas family. It has 36 protons and 48 neutrons. Its symbol is Kr. <span>Krypton, like the other noble gases, is used in lighting and photography. Krypton was discovered in Britain in 1898 by Sir William Ramsay, a Scottish chemist, and Morris Travers, an English chemist, in residue left from evaporating nearly all components of liquid air. Neon was discovered by a similar procedure by the same workers just a few weeks later.</span>

Answer:
Explanation:
We are asked to find the energy given mass, specific heat, and change in temperature. Therefore, we must use this formula;
The mass is 15 grams and the specific heat is 0.129 J/(g×°C). Let's calculate the change in temperature.
- ΔT= final temperature - initial temperature
- ΔT= 85 °C- 22°C = 63°C
Now we know all the values:
Substitue the values into the formula.
Multiply the first numbers together. The grams will cancel.
Multiply again, this time the degrees Celsius cancels.
<u>121.905 Joules</u> are required.
