Using the table of standard formation enthalpies that you'll find under the aleks data tab, calculate the reaction enthalpy of this reaction under standard conditions:
c2h5oh(l)+3o2(> 2co2(g)+3h2o(l)
round your answer to the nearest whole number.

Use the table to identify the phase and phase changes of the elements under the given conditions. write the name of the substance, phase, or phase change. when the temperature in a room increases from 25°c to 33°c, changes from a solid to a liquid. in a lab, methane and nitrogen are cooled from -170°c to -200°c. the methane freezes and the nitrogen . when gold is heated to 2,856°c it changes from a liquid to a .
