replies: text: Chalk is generally considered to be calcium carbonate. Other Group I and II metal carbonates may also be present. That said, magnesium carbonate chalk is, indeed, a type of chalk. I guess another way to put this is that "chalk" is an ambiguous term used to describe a variety of metal carbonates. Because MgCO3 is *not* necessarily what we'd be talking about (most of the time) when talking about chalk, I disagree that the term should be on top. (Although I would say that the way the article is now written, it isn't surprising that people come away from it misinformed. Clarification should be made.)174.130.71.156 (talk) 22:32, 28 October 2022 (UTC)

message: In the "Forms" section, it writes the formula of nesquehonite, the trihidrate of magnesium carbonate, is , but suddenly in the "Chemical properties"/"Decomposition" section writes the formula of the same chemical may be written as , confusing students is the molecular formula of nesquehonite  or , which are two distinct chemicals. That imports confusion (suspicion) are the molecular formulas of other hydrates (ammines, and other complexes) of magnesium carbonates, and all metal carbonates, sulfates, phosphates and other salts and other chemical compounds, all across the Wikipedia website, really true.
