Answer:
<h3><em>What is filteration</em><em>:</em></h3>
Filtration, the process in which solid particles in a liquid or gaseous fluid are removed by the use of a filter medium that permits the fluid to pass through but retains the solid particles. ... In some processes used in the production of chemicals, both the fluid filtrate and the solid filter cake are recovered.
<h3><em>When</em><em> </em><em>do</em><em> </em><em>we</em><em> </em><em>use</em><em> </em><em>it</em><em>:</em></h3>
<em>Filtration is used to separate particles and fluid in a suspension, where the fluid can be a liquid, a gas or a supercritical fluid. Depending on the application, either one or both of the components may be isolated.</em>
<h3><em>In</em><em> </em><em>order</em><em> </em><em>to</em><em> </em><em>separate</em><em> </em><em>a</em><em> </em><em>salt-water</em><em> </em><em>mixture</em><em>,</em></h3><h3><em>should</em><em> </em><em>a</em><em> </em><em>student</em><em> </em><em>use</em><em> </em><em>filtration</em><em>:</em></h3>
The mixture can be separated by filtration, by dissolving the mixture in water. Salt will dissolve in the water, whereas sand will not.

Answer:
36 KJ of heat are released when 1.0 mole of HBr is formed.
Explanation:
<em>By Hess law,</em>
<em>The heat of any reaction ΔH for a specific reaction is equal to the sum of the heats of reaction for any set of reactions which in sum are equivalent to the overall reaction:</em>
H 2 (g) + Br 2 (g) → 2HBr (g) ΔH = -72 KJ
This is the energy released when 2 moles of HBr is formed from one mole each of H2 and Br2.
Therefore, Heat released for the formation of 1 mol HBr would be half of this.
Hence,
ΔHreq = -36 kJ
36 KJ of heat are released when 1.0 mole of HBr is formed.
