Answer:
The correct answer is option C.
Explanation:
Kr is the symbol of a noble gas named krypton.It belongs to the group 18 of the periodic table in which all the elements are less reactive.
These noble gases are highly inert and less reactive due to:
- Completely filled electronic configuration in their valence shell.
- High ionization enthalpies.
- Positive value of electron gain enthalpy.
Nuclear energy
Nuclear reactors use fission, or the splitting of atoms, to produce energy. Nuclear energy can also be produced through fusion, or joining (fusing) atoms together.
Explanation:
P1V1 = P2V2
(100.7 kPa)(0.75 L) = (99.8 kPa)V2
V2 = (100.7 kPa)(0.75 L)/(99.8 kPa)
= 0.757 L
Answer:
184.46
Explanation:
(84.7°c x 9/5)+32=184.46 °F
Answer is: A. adding heat to the product mixture.
Balanced chemical reaction:
CO(g) + 3H₂(g) ⇄ CH₄(g) + H₂O(g); ΔH = -206.1 kJ.
This reaction is exothermic, which means that heat is released.
According to Le Chatelier's principle when the reaction is exothermic heat is included as a product and when the temperature increased, the heat of the system increase, so the system consume some of that heat by shifting the equilibrium to the left.
