Chemistry

tatuchka [14]2 years ago

The <u>secretion</u><u> </u>of acids, buffers, enzymes, and water aids in the breakdown of food.

The food moves through the gastrointestinal tract and breaks down into smaller particles for energy, cell repair, and growth.

Digestion begins when eating and chewing food with the help of teeth in the mouth, then it goes down to the small intestine.

While moving through the gastrointestinal tract it mixes with juices, acids, enzymes, and water which disintegrates the large molecules of food into smaller ones and makes it suitable for assimilation and absorption in the body.

Measurements show that the enthalpy of a mixture of gaseous reactants decreases by 162. kJ during a certain chemical reaction, w
puteri [66]

Answer:

= -356KJ

<em>therefore, the reaction where heat is released is exothermic reaction since theΔH is negative</em>

Explanation:

given that enthalpy of gaseous reactants decreases by 162KJ and workdone is -194KJ

then,

change in enthalpy (ΔH) = -162( released energy)

work(w) = -194KJ

change in enthalpy is said to be negative if the heat is evolved during the reaction while heat change(ΔH) is said to be positive if the heat required for the reaction occurs.

At constant pressure the change in enthalpy is given as

ΔH = ΔU + PΔV

ΔU = change in energy

ΔV = change in volume

P = pressure

w =  -pΔV

therefore,

ΔH = ΔU -W

to evaluate  energy change we have,

ΔU =ΔH + W

ΔU = -162+ (-194KJ)

= -356KJ

<em>therefore, the reaction where heat is released is exothermic reaction since theΔH is negative</em>
