Standar molar entropies from a table:
CH3OH (l): 126.8 J / K*mol
O2 (g): 205.1 J/ K*mol
CO2(g): 213.7 J/K*mol
H2O(g): 188.8 J/J*mol
Now use the coefficients of the reaction and sum the product entropies less the reactant entropies:
4*188.8 + 2*213.7 - 3*205.1 - 2* 126.8 = 313.7 J/mol*K
Answer: option C) +3173.766 J/mol*K
Density is therefore called an intensive property of matter. Mass<span> is the amount of matter contained in an object and is commonly measured in units of </span>grams<span>(g). </span>Volume<span> is the amount of space taken up by a quantity of matter and is commonly expressed in</span>cubic centimeters<span> (cm</span>3<span>) or in </span>milliliters<span> (ml) (1cm</span>3<span> = 1 ml).</span>
The substance that can be broken down by chemical means from the choices given is CO (Carbon monoxide). Carbon monoxide is a compound made up of carbon and oxygen and can therefore be broken by chemical means.
