Answer
Two different elements have similar chemical properties when they have the same number of valence electrons in their outermost energy level. ... Elements in the same column of the Periodic Table have the same number of valence electrons – that's why they have similar chemical properties.
Answer:
Scale Factor: 1 : 2
X = 11
Explanation:
3 / 3 = 1
6 / 3 = 2
The scale factor should be 1:2
So 'X' should be 11 since 5.5 * 2 = 11
The question is incomplete. But this is a typical thermodynamic problem. Looking at the given data and knowing that it is an isothermal process, the most probable question would be, the final pressure of the system. The solution is as follows:
For state 1,
PV=nRT
P₁(100 L)(1 m³/1,000 L) = (5 mol)(8.314 m³Pa/molK)(300 K)
P₁ = 124,710 Pa
For isothermal process:
P₁V₁ = P₂V₂
(124,710 Pa)(100 L)= P₂(500 L)
Solving for P₂,
<em>P₂ = 24,942 Pa</em>
It's observation and a hypothesis.
