Formula of anion: Anion is a negatively charged specie;
NO₃⁻
Answer:
It is an example of coupling an exogenic reaction to an endogenic reaction.
Explanation:
The endergonic reaction is typically being pushed by coupling it to strongly exergonic reaction. This is in most cases via shared intermediates. Most chemical reactions are endergonic in nature. In other word, the are not spontaneous (i.e ΔG>0). Energy must also be applied externally to initiate the reactions. The reactions can also be coupled to exergonic reactions (with ΔG<0) to initiate them through a process known as share intermediate. Because Gibbs Energy can be summed up (i.e is a state function), the combined ΔG of the coupled reaction will be thermodynamically favorable. The decomposition of calcium carbonate is a typical example.
<h2>Answer:</h2>
At 189 K volume = 32.0 cm
As volume of gas is directly proportional to temperature.
As the temperature increase the volume of gas will also increase.
so
Volume at 1 K = 32/189
Volume at 242 K = 32/189 * 242 = 40.97 cm.
Gas occupy 40.97 cm volume at 242 K.
