If you were going to graphically determine the enthalpy of vaporization, δhvap, for this liquid, what points would you plot
Klio2033 [76]
It depends on what type of graph you have. The easiest would be using a H-T diagram. Enthalpy of vaporization is the physical change from liquid to vapor. It occurs at a constant pressure and a constant temperature. As shown in the picture, 1 point is drawn on the subcooled liquid, and another point of the saturated vapor isothermal line. Now, the difference between those two points is the value for the enthalpy of vaporization of water.

How many liters of carbon dioxide will 0.5 mole of lithium hydroxide (LiOH) absorb? (One mole of any gas occupies 22.4 L under c
Svet_ta [14]

Answer:

0.5 moles of LiOH will absorb 5.6 L of CO_2

Explanation:

According to law of conservation of mass, the sum of mass on the reactant side must be equal to the sum of mass on product side.

The balanced chemical equation is:

2LiOH+CO_2\rightarrow Li_2CO_3+H_2O

2 moles of LiOH absorb 1 mole of CO_2 i.e. 22.4 Liters at STP

0.5 moles of LiOH absorb

=\frac{22.4}{2}\times {0.5}=5.6Liters

0.5 moles of LiOH will absorb 5.6 L of CO_2
