Answer:
The answer to your question is 2.32 atm
Explanation:
Data
P = ?
n = 0.214
V = 2.53 L
T = 61°C
R = 0.082 atm L/mol°K
Formula
PV = nTR
solve for P
P = nRT/V
Process
1.- Calculate the temperature in K
°K = °C + 273
°K = 61 + 273
= 334
2.- Substitution
P = (0.214 x 0.082 x 334) / 2.53
3.- Simplification
P = 5.86/2.53
4.- Result
P = 2.32 atm

Final answer:
The two gases that cannot be broken down by chemical means are He (helium) and Xe (xenon).
Explanation:
According to the question, we are looking for two gases that cannot be broken down by chemical means. Chemical means refer to chemical reactions that break down compounds into their constituent elements. The options given are (1) CO and He, (2) CO and NH3, (3) Xe and He, and (4) Xe and NH3.
CO and NH3 are both compounds that can be decomposed by chemical means. However, both He (helium) and Xe (xenon) are noble gases that cannot be broken down by chemical means. This is because noble gases have stable electron configurations, making them unreactive and resistant to chemical reactions. Therefore, the correct answer is (3) Xe and He.

A: Scientists have not yet gotten a fusion reaction to happen on Earth.
B: Per gram of fuel, fission releases more energy than fusion.
C: The energy from fusion cannot yet be converted to electricity.
D: Fusion requires conditions that use too much energy to maintain.
Answers
According to the nuclear fission and nuclear fusion reactions,energy from fusion cannot yet be converted to electricity.
What is nuclear fission and nuclear fusion?
There are two types of nuclear reactions which are nuclear fusion and nuclear fission .They involve the combination and disintegration of the element's nucleus respectively.
In nuclear fission, the nucleus of the atom is bombarded with electrons of low energy which splits the nucleus in to two parts .Large amount of energy is released in the process.It is used in nuclear power reactors as it produces large amount of energy.
In nuclear fusion,on the other hand, is a reaction which occurs when two or more atoms combine to form a heavy nucleus.Large amount of energy is released in the process which is greater than that of the energy which is released in nuclear fission process.

Fusion results in a lot of energy. The sun uses fusion reactions to burn. So, if we were using fusion reactions, we would have little suns going off. Nuclear bombs often use a combination of fission and fusion reactions to maximize devastation. However, we do not currently have the ability to control or convert the energy produced by a fusion reaction.
(2) The entropy of the LiBr(aq) is less than the entropy of the water.
(3) The dissolving of the LiBr(s) in water is an endothermic process.
(4) The dissolving of the LiBr(s) in water is an exothermic process.
Answers
The statement best explains why the thermometer reading initially increases when LiBr(s) is dissolved in the water is the dissolving of the LiBr(s) in water is an exothermic process.
What is a thermometer?
A thermometer is an instrument that is used to measure the temperature of an object.
An exothermic process is in which the heat and energy is released in the outer system.
Thus, the correct option is (4) The dissolving of the LiBr(s) in water is an exothermic process.

Answer:
Explanation:The buffer is a mixture of ammonia (NH3) and ammonium (NH4+). ... Since ammonia (NH3) is a weak base, it will have a pH above 7 and since ammonium (NH4+) is a weak acid, it will have a pH below 7. Ammonia (NH3) is a weak base and ammonium (NH4+) is a weak acid. Ammonia (NH3) is the conjugate base of ammonium (NH4+).
Final answer:
Ammonium ion, in collaboration with ammonia, acts as a buffer solution. The point at which it becomes a buffer is when the concentrations of NH3 and NH4+ are equal, typically around a pH of 9.25, enabling them to neutralize other strong acids or bases to stabilize the pH.
Explanation:
Ammonium ions (NH4+) act as a buffer solution in conjunction with a weak base (ammonia, NH3). This system can balance the pH of a solution by either absorbing excess hydronium ions (H3O+) when the solution becomes too acidic or by producing more when the solution becomes too basic. The point at which the ammonium ion acts as a buffer solution is the pH at which the concentrations of the weak base (NH3) and its conjugate acid (NH4+) are equal. This is typically around a pH of 9.25, where the ammonium ion and its conjugate base, ammonia, can effectively neutralize additional strong acids or bases, thereby stabilizing the pH of the solution.
