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.
Answer:
NaOH and HCl
Explanation:
The reaction of sodium hydroxide, NaOH, with hydrochloric acid, HCl, produces NaCl and water.
Answer:
The thermodynamic parameter which is of significance in this case is the 'Reduction Potential' for molecular bromine which is ~ +1.1 v vs N.H.E. In other words, it is a strong oxidizing agent. The bromine will oxidize sulfur compounds in which the valence of sulfur is lower than six to sulfate.
There are many possible reactions. Here is one possible example:
Na2 S2O3 + 4Br2 + 5 H2O = 2NaHSO4 + 8 HBr
Answer: A. 11.15
Explanation:
The pH of a solution is given by the formular; pH = -log [H+].
pH = - log [ 7.0 x 10 ∧-12]
= 12 - log 7
= 12 - 0.845
= 11.15
Answer:
<h3>when the temperature of a solution increases then,solubility of solid solute increases...</h3>
