I believe the choices
in this question are:
A. Lowering the
temperature of the reaction. <span>
B. Lowering the enthalpy of the reaction.
C. Decreasing the volume of the system.
D. Adding oxygen gas.
E. Decreasing the pressure of the system. </span>
<span>From the choices
above, A, B, and D will result in creation of more Cl2 gas.</span>
Answer: Bohr proposed his quantized shell model of the atom to explain how electrons can have stable orbits around the nucleus.
so C would seems to be right.
Explanation: The energy of an electron depends on the size of the orbit and is lower for smaller orbits. Radiation can occur only when the electron jumps from one orbit to another. The atom will be completely stable in the state with the smallest orbit, since there is no orbit of lower energy into which the electron can jump.

Answer:
The percentage yield of LiOH is 39.9%
Explanation:
From the question given above, the following data were obtained:
Theoretical yield = 47.4 g
Actual yield = 18.9 g
Percentage yield =?
The percentage yield of LiOH can be obtained as follow:
Percentage yield = Actual yield / Theoretical yield × 100
Percentage yield = 18.9 / 47.4 × 100
Percentage yield = 1890 / 47.4
Percentage yield = 39.9%
Therefore, percentage yield of LiOH is 39.9%
