Answer:
Perfectly Specified
Explanation:
Pressure, P = 0.9 atm
Boiling point = T
Number of components C = 1
Number of phases P = 2
Using Gibbs phase rule as:
F = C - P + 2
F = 1 - 2 + 2 = 1
At Pressure = 0.9 atm, boiling point is T which means that the temperature is also fixed which is equal to 96.7 °C . The data taken from steam table.
In given problem, the pressure is fixed so temperature is also fixed.
The system is perfectly specified.
Answer:
CH4+2O2-->2H2O+CO2 chemical reaction
First of all, we convert the amount of item given in moles into grams. Each mol of steam is 18 grams of steam. Such that the heat released during the evolution of per gram of steam is,
H = (2.01 J/goC)(160 - 100) + 2260 J/g + (4.179 J/gC)(100 - 0) + (333.5 J/g) + (2.09 J/gC)(45oC)
H = 3226.05 J/g
Then, we multiply this value by 18 g to get the final answer which is equal to 58068.9 Joules.
Answer:Why is Dalton credited with proposing the first atomic theory if Democritus was talking about atoms almost 2,200 years earlier?
- Democritus' ideas were not supported by evidence
- Dalton's theory was the first scientific theory because it relied on scientific investigative processes.
- Dalton's theory was supported by evidence and repeated investigation.
Explanation: 1: Democritus' ideas were not supported by evidence
2: Dalton's theory was the first scientific theory because it relied on scientific investigative processes.
3: Dalton's theory was supported by evidence and repeated investigation.
Answer: The given statement is false .
Explanation:
Noble gases are least reactive elements in the periodic table. Noble gases have fully filled stable electronic configuration which the reason of their inert and lest reactive nature.
For example : Helium. Neon, argon etc.
