Ethylene glycol, commonly used in automobile antifreeze, contains only carbon, hydrogen and oxygen. combustion analysis of a 23.46mg sample yields 20.42 mg of water and 33.27 mg of carbon dioxide. what is the empirical formula of ethylene glycol? if other experiments determine that it's molar mass is 62.0g/mol, what is it's molecular formula?

Suppose a pair of chemical compounds a and b can react in two different ways: a + b -> c reaction 1 gives product c. a + b -> d reaction 2 gives product d. the following facts are known about the two reactions: . reaction 1 is endothermic and reaction 2 is exothermic. if a reaction vessel is charged (filled) with a and b , then at first d is produced faster than c. use these facts to sketch a qualitative reaction energy diagram for both reactions. note: because these sketches are only qualitative, the energies don? t have to be exact. they only have to have the right relationship to each other. for example, if one energy is less than another, that fact should be clear in your sketch.
