Trend in thermal stability down group 2
WebThermal Stability is the decomposition of a compound on heating. The higher the temperature needed to decompose something, the more thermally stable it is. In group 1 and 2, the nitrates and carbonates get more stable down the group. The rest of group 1 follow the same pattern. (substitute Na, K etc where Li is). WebTrend in thermal stabilities Going down Group 2, more heat is needed to break down the carbonate and nitrate ions The thermal stability of the Group 2 carbonates and nitrates …

WebAlkane. In organic chemistry, an alkane, or paraffin (a historical trivial name that also has other meanings ), is an acyclic saturated hydrocarbon. In other words, an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single. [1] Alkanes have the general chemical formula CnH2n+2.
