Consider the exothermic reaction
alisha [4.7K]

Answer:

The answer to your question is -2855 J

Explanation:

Reaction

                     2C₂H₆  +  7O₂   ⇒   4CO₂  +  6H₂O

Formula

Heat of reaction = ΔHrxn = ΣΔHrxn products - ΣΔHrxn reactants

Substitution

ΔHrxn = { 4(-393.5) + 6(-241.8)} - {2(-84.7) + 7(0)}

ΔHrxn = {-1574 -1450.8} - {-169.4}

ΔHrxn = -3024.8 + 169.4

ΔHrxn = -2855.4 J

What do you think happens to the air in the collid when ice cream melts ?
vichka [17]

The air escapes into the atmosphere.

An <em>emulsion</em> is a colloidal dispersion of one liquid in another liquid in which it does not dissolve.

<em>Ice cream</em> is essentially an emulsion of the fat in milk with a sugar solution trapped in a network of small ice crystals. Other chemicals are added to prevent the emulsion from separating, and air bubbles are mixed into the semisolid mixture.

<em>Up to 50 %</em> of the volume of ice cream can be air.

When the ice cream melts, the air bubbles are <em>no longer trapped</em>. They just escape into the atmosphere.

If you re-freeze the melted ice cream, its volume will be much less than the original.
