Answer:
The temperature of the gas is 876.69 Kelvin
Explanation:
Ideal gases are a simplification of real gases that is done to study them more easily. It is considered to be formed by point particles, do not interact with each other and move randomly. It is also considered that the molecules of an ideal gas, in themselves, do not occupy any volume.
The pressure, P, the temperature, T, and the volume, V, of an ideal gas, are related by a simple formula called the ideal gas law:
P*V = n*R*T
where P is the gas pressure, V is the volume that occupies, T is its temperature, R is the ideal gas constant, and n is the number of moles of the gas.
In this case:
- P= 470 mmHg
- V= 570 mL= 0.570 L
- n= 0.216 g= 0.0049 moles (being the molar mass of carbon dioxide is 44 g/mole)
- R= 62.36367
Replacing:
470 mmHg*0.570 L= 0.0049 moles* 62.36367 *T
Solving:
T= 876.69 K
<em><u>The temperature of the gas is 876.69 Kelvin</u></em>
Answer:
Acid rain's effect on stone is a chemical change.
Explanation:
Acid rain has hydrochloric acid which reacts with the calcium carbonate in the stone.
I hope this helps. (Sorry if i am wrong)
Answer:
Two design criteria for the design of the ammonia making process are;
1) Sustainable hydrogen production by renewable energy
2) Sustainable use of the ammonia-water thermal absorption cycle to retrieve the ammonia present in the waster water
Explanation:
Ammonia is produced from natural gas in the following process;
H₂ + RSH → RH + H₂S
H₂S + ZnO → ZnS + H₂O (Waste water)
CH₄ + H₂O → CO + 3H₂
CO + H₂O → CO₂ + H₂
Ammonia is then produced by reacting the produced hydrogen with nitrogen in the presence of a catalyst in a process known as the Haber-Bosch process as follows;
3H₂ + N₂ → 2NH₃
The
The design criteria for the design of the ammonia making process therefore as follows;
1) Sustainable use of renewable energy to produce hydrogen gas from the electrolysis of water
2) Use of the ammonia-water thermal absorption cycle to retrieve the ammonia present in the waster water.
