Answer: 1.7 moles
Explanation:
Given that:
Volume of water V = 1.5L
(since 1 liter = 1dm3
1.5L = 1.5dm3)
Temperature T = 100°C
Convert Celsius to Kelvin
(100°C + 273 = 373K)
Pressure P = 3.5 atm
Number of moles of steam N = ?
Note that Molar gas constant R is a constant with a value of 0.0082 ATM dm3 K-1 mol-1
Then, apply ideal gas equation
pV = nRT
3.5atm x 1.5dm3 = n x (0.0082 ATM dm3 K-1 mol-1 x 373K)
5.25 = n x 3.06
n = 5.25/3.06
n = 1.7 moles
Thus, 1.7 moles of steam is present
Answer:
Kush would have been able to fight better and probably would have never been invaded by Egypt, and they could have beaten the Assyrians when they tried to takeover Egypt. And the 25th dynasty would have continued.
Explanation:
that is my explanation and answer^
We have to fill the gap
The correct answer is: Metals with the largest atoms and the smallest number of valence electrons and non-metals with the smallest atoms and the greatest number of valence electrons are the most reactive.
Reactivity of any species depends on ease of release or gain of electron. The species which can release electron easily from valence shell, the species is more reactive whereas the species which can accept electron to its valence shell easily is also more reactive.
Option (C) Electron.
Explanation:
Because Vander wall forces arises due to the small moment when a temporary dispole is created between the atoms. The more the electron the stronger the polarization will be and hen stronger bond.
