Consider the equation ∆G = –nFE, where F = 9.648533289 x 104 C/mol. Given that n is the mole of e– transferred and the following relationships, prove that ∆G will be in units of Joules.

See explanation below.

Explanation:

In the equation  ∆G = –nFE,  E is the electromotive force ( cell potential ) in Volts.

Now in turn a Volt is defined as the potential difference that will impart one joule of energy per coulomb of charge that moves through two points.

V = J/C where J is Joules and C is coulombs of charge

Therefore in terms of units the equation will give us units of Joules:

[ mol] x [C/mol] x [J/C] = [J]

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.

shield volcanos are angry and get mad over the smallest things so much that there heads erupt   pahoehoe and a'a lava. a composite volcano is the poller opposite of a shield volcano. its   peaceful thing and knows how to control its emotions.
