Evaluate the drafted changes
Lead:

The lead has been expanded upon to give a better idea of what difluoromethane is and covers the included sections (uses and environmental fate) to give a well put together summary of what difluoromethane is. The mention of the Clean Air Act in the lead section could be expanded upon in the environmental fate section as well, giving more background as to why difluoromethane is and exception and what it means when it says it has a low production of tropospheric ozone.

Content:

The first few sentences under "Uses" seem a bit disconnected from the rest of the section. They would probably fit into one of the paragraphs well, although the second sentence seems to be a sentence fragment that doesn't really convey any information. Instead of leaving (aka freon) I would change aka to "such as" or something a bit more formal like that. Instead of saying "Last year..." put the actual year since this is an ongoing article and when someone is reading this in the future they likely will not know what year it was added. The first sentences under uses say that Difluoromethane is often used as a fire extinguishant, but then the last paragraph says the molecule is mildly flammable. Can you give clarification to this? Is there a certain type of difluoromethane that is used for fire extinguishing? All of the added content is relevant to difluoromethane, it is still in the process of being organized though.

Tone and Balance:

The article is not written with any apparent biases and remains neutral giving only the facts about the molecule.

Sources and References:

Make sure to use the references that are already cited in the article when you transfer over to your sandbox. Some of the information in your sandbox is not referenced, but on the published page it is. From what I could open, the first reference on the sandbox page is only a list of names that does not really give any information toward difluoromethane. You may want to replace it with an alternative reference. The other references in the sandbox are relevant to the article, however majority of them are over 10 years old. Difluoromethane may be an older molecule with not much recent information on it, but if so you may want to reference that in the article?

Organization:

The article is so far well organized. The only suggestion I might have is listing the toxicity before the environmental fate. Otherwise, each section seems to be well organized and coming along very nicely.

Images and Media:

N/A

Overall Impressions:

The information added has increased the readability of the Wiki page and gives more information about Difluoromethane. The original wiki page was pretty barren and Sarah has done a good job of flushing out the article more and providing more information regarding this chemical.
