Which of the following is not a concern regarding the use of corn as biofuel

The correct answer for above statement is:

The color of corn is different than the color of gasoline or coal.

Explanation:

While there was a great potential to use grain as a biofuel the cost of corn-based commodities rushed up throughout the world as well as any other goods as more area was being given to corn. The only difficulty though is corn isn't the best specialist for biofuels, there are a lot of additional choices that work great and aren't as costly to grow.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
