Answer:
Elements in the noble gas family are considered stable because their outer energy levels are very low.
Explanation:
Noble gas is also called inner gases because they are stable due to the completion of outermost shell. Other elements in the periodic table are very reactive so they wants to achieve the electronic configuration of noble gas so that's why they make chemical bonds with each other.
Answer:
the sun is directly behind your head
Explanation:
The reason why we can see a rainbow is caused by sunlight and atmospheric conditions
a. Using the Clausius-Clapeyron equation
ln P1/P2 = (-Hvap / R) (1/T1 - 1/T2)
P1 = 197 mm Hg
P2 = 448 mm Hg
T1 = 23 C = 296 K
T2 = 45 C = 318 K
R = 8.314 J/mol-K
Solving for Hvap
Hvap = <span>29225.43 J/mol
b. For normal boiling point
</span>P1 = 197 mm Hg
P2 = 760 mm Hg (normal pressure)
T1 = 23 C = 296 K
T2 = ?
R = 8.314 J/mol-K
Hvap = 29225.43 J/mol
ln P1/P2 = (-Hvap / R) (1/T1 - 1/T2)
Use the equation to solve for T2
solid, liquid, gas i think this the correct answer i guess so
Im sure that the answer is C, correct me if im wrong.
