Ethanol undergoes combustion in oxygen to produce carbon dioxide gas and liquid water. The standard heat of combustion of ethanol, c2h5oh(l), is -1366.8 JK/mol. Given that [co2(g)] = -393.5kg/mol and [h20(l) = -285.8 KJ/ mol, what is the standard enthalpy of formation of ethanol?

Explanation:

Heat of combustion of = -1366.8 kJ/mol

Heat of formation of = -393.5 kJ/mol

Heat of formation of = -285.8 kJ/mol

The reaction is

Assuming is the standard enthalpy of formation of ethanol

The standard enthalpy of formation of ethanol is .

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

b. examine and describe cells
