Fumaric acid being the trans isomer will have the least stearic hindrance as the carboxylic acid groups will be on the different sides of the double bonds-hence causing the least electronic repulsion. Fumaric acid will be more stable as compared to maleic acid.
Maleic acid and fumaric acid are cis-trans isomers of each other.

yes
Malic Acid, Citric acid, Isocitric Acid, Succinic Acid and Fumaric Acid.
just tried it. a dash of reagent grade fumaric acid was covered in janator strength non detergent ammonia. no observable reaction....
Fumaric acid is dried in an oven at a relatively low heat - below 130 degrees centigrade - to evaporate any water that might be left over from formation. If it is heated above 130 degrees, the fumaric acid starts to decompose and form maleic acid, maleic anhydride, carbon monoxide and carbon dioxide. The acid may be dried for a number of reasons. Commercially because water has weight but no value, it is cheaper to transport completely dry fumaric acid. Water may also cause unwanted reactions with other chemicals which the fumaric acid is eventually added to. Removing the water then removes the reactions.
An aspartase is an enzyme which catalyzes the deamination of aspartic acid to fumaric acid and ammonia.
trans-butenedioic acid,C4H4O4 also called fumaric acid
1. Maleic anhydride is hydrated. This produces maleic acid. 2. Maleic acid is isomerised in the presence of a catalyst. 3. Fumaric acid is produced. Easy as that! (Except the temperature and pressure have to be kept controlled throughout)
trans-HO2CCH=CHCO2H or C4H4O4
Yes. Yes it would
Examples are: ethanol, lactic acid, butyric acid, acetic acid, acetone, fumaric acid.
