Question

Please answer i will mark brainliest
Some ores contain metal carbonates and some ores contain metal oxides. Name the type of reaction that happens when a metal carbonate is heated.

Please help and explain in detail (i have a test tomorrow so i need to understand how this works) i will give brainliest for good answers not the fastest answers lol

PLEASE ACTUALLY ANSWER (i wasted 88 points earlier cuz some idiot just wrote idk and took the points)

Answer 1

Answer:

Those metal carbonates which do decompose leave a residue of the metal oxide and evolve carbon dioxide in the process, eg:

ZnCO3(s) → ZnO(s) + CO2(g)

At an elementary level, the relative thermal stability of the carbonates of the metals cannot easily be explained in terms of simple ideas of bonding in these compounds. A simple relationship between the reactivity of the metal and the stability of its compounds, such as the carbonate here, will have to suffice.

With abler and older students it may be appropriate to refer to the polarization (distortion) of the electron cloud of the carbonate ion by the metal ion, and that this is bound to be more pronounced when the metal ion is doubly, rather than singly charged, and small. Polarization eventually leads to abstraction of oxygen from the carbonate ion, producing the oxide ion and a carbon dioxide molecule. The greater the polarization, the lower the temperature needed to decompose the carbonate.
