A physical exothermic process
Answer: The middle hydrogen is surrounded by 4 electrons, the middle hydrogen is bonded to 2 elements, and there are too many electrons in the final structure are correct.
Explanation: I just did this question and got the correct answers.
When a neat, ordered chemical is change into a more disordered chemical, then there is an increase in ENTROPY.
Entropy refers to the degree of disorderliness in a reacting system. The degree of entropy is considered to be zero, when there is no disorderliness. The degree of entropy increases as the disorderliness increases. <span />
First you need to write out the original equation.
It needs to be balanced, though, so after balancing it should look like this:
The ionic equation would look like this. (Only aqueous solutions can be split up).
The net ionic equation only contains the products that are not aqueous. Therefore, the final net ionic equation should be:
So your answer is C.
