Carbonates are decomposed by heating in oxides and carbon dioxide; the temperatures of decomposition are:
- Beryllium carbonate: decomposed at room temperature.
- Magnesium carbonate: 400 0C
- Calcium carbonate: 900 0C
- Strontium carbonate: 1 280 0C
- Barium carbonate: 1 360 0C
- Radium carbonate: I have not yet found data.
An element in group 2 of the periodic table typically forms 2 covalent bonds, as it has 2 valence electrons available for bonding. This allows the element to achieve a full outer shell and attain stability.
Carbonates are compounds that contain the carbonate ion (CO3^2-) and are formed by the reaction of carbon dioxide with a base. Hydroxides are compounds that contain the hydroxide ion (OH-) and are formed by the reaction of a metal with water. Carbonates are typically insoluble in water, while hydroxides are usually soluble.
The exception to the trend of increasing ionization energy across a period in the periodic table occurs when transitioning from group 2 to group 3 elements. This is because the group 3 elements have a slightly lower ionization energy compared to the group 2 elements due to the added stability of having a half-filled or fully-filled subshell.
When metals react with acids,hydrogen is liberated,(since all acids contain hydrogen) eg:Na2 + H2SO4 -> Na2SO4 + H2 When metal carbonates react with acids carbon dioxide is liberated. eg:Na2CO3 + H2SO4 -> Na2SO4 + H2O + CO2
The main difference is the presence of a hydroxyl (-OH) group on the 2' carbon of the ribose sugar in ribonucleotides, whereas deoxyribonucleotides lack this hydroxyl group. This small difference affects the stability and structure of RNA and DNA molecules. Ribonucleotides are used for RNA synthesis while deoxyribonucleotides are used for DNA synthesis.
The size of the group 2 ions gets bigger as we go down the group. Hence, their polarising power also decreases. So, the carbonates are less polarised as we go down the group, requiring more energy to decompose them. Polarising power is the ability of the ion to attract the bonding pair of electrons towards itself.
over 1000 degrees, but it does change with the other metals, i guess you'll have to keep looking
Ammonium carbonate ((NH4)2CO3) is a specific reagent that precipitates the cations of group 2 in qualitative analysis. It forms insoluble carbonates with cations such as calcium, strontium, and barium, allowing for their separation from other cations in the group.
Transistors need thermal stabilization because the operating point of a transistor junction, similar to a diode, is affected by temperature. In fact, this can cause thermal runaway, and device destruction, if the circuit design does not compensate for this. Answer mostly correct but the operating point of a transistor must remain fixed as temperature varies whether going low or higher. that is mainly the concern about. not runaway that is caused by bad design.
The chemical classification group that dolomite belongs to is a carbonate. Dolomite is an element of calcium magnesium carbonate and has the chemical formula CaMg(CO3)2.
If your Group 2 cations are calcium, strontium or barium, add a solution containing sulphate ions, i.e. sulphuric acid or the sulphate of the Group I metal that is the Group I cations in your solution. The Group 2 cations will precipitate out with the sulphate ions. If you have beryllium or magnesium cations, then I don't know.

A mineral carbonate is a compound containing the carbonate ion (CO3^2-). Examples include minerals such as calcite (CaCO3) and dolomite (CaMg(CO3)2). Carbonates are common minerals in Earth's crust and play a key role in rock formation.
Carbonates are compounds that contain the carbonate ion (CO3^2-) and are formed by the reaction of carbon dioxide with a base.
