The practical work inside the lab includes lab equipments, chemicals, and the practical outside a laboratory is more about conservation of nature and practicals include natural things in their living areas.
What are lab practicals?
Practicals are set up stations with lab equipments and chemicals and where students learn practical of the theoretical statements.
The exams of practicals are done to test the leaning of chemistry of the students.
Thus, the practical work inside the lab includes lab equipments, chemicals, and the practical outside a laboratory is more about conservation of nature and practicals include natural things in their living areas.

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
There are two possible situations.
1) If a phase change is not occurring, then the heat added contributes to increased translational energy of the particles. What that means is the particles move/vibrate faster.
2) If a phase change is occurring, then the heat added contributes to the breaking of bonds or intermolecular forces (depending on the chemical nature of the matter you're dealing with).
Answer:
This soda is brown, sweet, has high carbonation, and is about 200 calories when consumed.
Explanation:
:)
The equilibrium constant<span> of a chemical reaction is the value of the reaction quotient when the reaction has reached </span>equilibrium<span>. An </span>equilibrium constant<span> value is independent of the analytical concentrations of the reactant and product species in a mixture, but depends on temperature and on ionic strength.</span>
