"in the absence of an adequate supply of oxygen, yeasts obtains metabolic energy by fermentation of glucose to produce ethanol. c6h12o6(s) latex: \longrightarrow⟶ 2 c2h5oh(l) + 2 co2(g) use the standard enthalpies of formation to calculate δh for this reaction" substance δho glucose(s) -304.5 kcal/mol co2(g) -93.9 kcal/mol c2h5oh(l) -66.4 kcal/mol

Explanation:

The balanced chemical reaction is,

The expression for enthalpy change is,

where,

n = number of moles

Now put all the given values in this expression, we get

Therefore, the enthalpy change for this reaction is -16.5 kcal

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
