Hello!
In this case, since the relationship between entropy and enthalpy for any process is defined below:
For the vaporization of ammonia or any liquid, we can write:
In such a way, solving the temperature of vaporization, or boiling point, we have:
Plugging in the given enthalpy and entropy of vaporization we obtain:
Best regards!
Answer:
Explanation:
Use the ideal gas equation:
Where:
- p is the pressure: 202.6kPa
- n is the number of moles: 0.050 mol
- T is the temperatue in absolute scale: 400K
- R is the universal constant for ideal gases: 8.314 L-kPa / K-mol
- V is the volume
Substitute and solve for V:
Convert to liters:
The answer is rounded to two significant figures.
An ionic compound is composed of anions and cations. A cation is a positively charged ion, and an anion is the opposite. A metal is composed of two or more cations. Since you need at least one cation and one anion for an ionic compound, the metal is not ionic.
In order to find the answer you must plug in the information to the frequency equation,
. C is the speed of light, 3.0 x 10^8. By plugging in the information you receive a frequency of
3.0 x 10^7 hz.
Answer: 330 K
Explanation: Charles Law
V1/ T1 = V2/ T2
Derive the equation to find T2
T2 = V2 T1 / V1
