A metal (1) carbonate decomposes at high temperature into a metal oxide and carbon dioxide gas. When 106g of metal (1) the carbonate decomposes, only 58.5% of it becomes originally the mass remained. What is probably the metal? The "(I)" in the middle of the name means that our unknown metal can images 1+ ions. The carbonate ion has the formula CO²
I'm sorry but I don't understand the question, particularly the portion " only 58.5% of it becomes originally". 58.5% becomes what? Please rephrase and repost.
