a)lithium nitrates and lithium carbonate All the carbonates in this Group undergo thermal decomposition to give the metal oxide and carbon dioxide gas.

For Li2CO3, however, the decomposition occurred at much faster rates than that for Na2CO3. The decomposition temperature of a substance is the temperature at which the substance chemically decomposes. this is an experiment on heating the nitartes and carbonates of the s-block element. This type of reaction is called a thermal decomposition. If decomposition is sufficiently exothermic, a positive …

2 NaHCO 3 (s) Na 2 CO 3 (s) + H 2 O (g) + CO 2 (g) This reaction takes place at a temperature of over 1200°C K 2 CO 3 2K + CO + O 2 The effect of heat on the Group 2 carbonates. The thermal decomposition of potassium carbonate to potassium produce, carbon monoxide and oxygen. Lithium Carbonate is the carbonate salt of lithium, a soft alkali metal, with antimanic and hematopoietic activities. The chemical formula of sodium carbonate (washing soda) is Na2CO3. write balanced equation for the thermal decomposition of this few nitrates & carbonates.? Thermal decomposition, or thermolysis, is a chemical decomposition caused by heat. The balanced equation for the decomposition of sodium bicarbonate into sodium carbonate, carbon dioxide, and water is: 2 NaHCO3(s) → Na2CO3(s) + CO2(g) + H2O(g) Like most chemical reactions, the rate of the reaction depends on temperature. $\ce{MgCO3}$ is also a bit unstable taking into consideration the above fact. The Facts. $\ce{BeCO3}$ is so unstable that it can only be kept in an atmosphere of $\ce{CO2}$. It describes and explains how the thermal stability of the compounds changes as you go down the Group. When it is heated above about 80°C it begins to break down, forming sodium carbonate, water and carbon dioxide. The reaction is usually endothermic as heat is required to break chemical bonds in the compound undergoing decomposition. When it is heated it undergoes a thermal decomposition reaction. In this regard the beryllium carbonate is the least stable alkali carbonate or in other words, an unstable alkali carbonate and readily decomposes into $\ce{BeO}$ and $\ce{CO2}$. This takes place above 500 degree C. For the case of pure Na2CO3, the thermal decomposition started from its melting point and continued as the temperature was increased, but at a very slow rate. Sodium hydrogen carbonate (also known as sodium bicarbonate or bicarbonate of soda) has the chemical formula NaHCO 3.
