Answer:
Explanation:
Uranium hexaflouride (UF6) has a triple point at (T, p) = (337 K,152 kPa) that means at pressure above 152kPa and temperature of 337 K ( 64 degree celsius) it becomes liquid .
If we have a (gaseous) sample of UF6 at atmospheric pressure and room temperature , and we keep cooling the sample , it will undergo a phase change of gas → solid.
<u>Answer:</u> The equilibrium constant for the given equation is 0.0315
<u>Explanation:</u>
We are given:
Total pressure in the container = 0.596 atm
The given chemical equation follows:
<u>Initial:</u> -
<u>At eqllm:</u> - 2x x
Evaluating the value of 'x'
The expression of for above equation follows:
The partial pressure of pure solids and pure liquids are taken as 1 in the equilibrium constant expression.
Putting values in above expression, we get:
Hence, the equilibrium constant for the given equation is 0.0315
Well if you go to Quiz-let it gives the answer the mass of a mole of compound is determined by adding the atomic masses of the atoms making up the molecules
Answer:
22
Explanation:
5.5 mol C3H8 • (4 mol H2O / 1 mol C3H8 ) = 22 mol H2O
Answer:
B
Explanation:
You might want to pick "A sound is created" No that answer is just fine. If you listen when sitting around a campfire, you might hear the crackling of what is burning. Burning is an excellent example of a chemical change. Wood becomes ash.
The answer is a change in the state of matter. (B). That need not indicate a chemical change. In fact, most of the time, a change in matter is a physical change.
Answer: B
