Thermal stability of carbonates increases in a group as we move from top to bottom and decreases in a period as we move from left to right. The thermal stability of hydrides decreases on moving down the group. Thermal stability increases down the group due to the decrease in the charge density of the metal cation. When is passed through solution of alkaline metal hydroxides - wherein . ... What is the correct order of thermal stability of carbonates of alkaline earth metals? The decreasing stability of the hydrogen halide is also reflected in the values of dissociation energy of the H-X bond $\begin{matrix}H-F&H-Cl&H-Br&H-I\\ 135\,kcal\,mol ^{-1}&103\,kcal\,mol ^{-1}&85\,kcal\,mol ^{-1}&71\,kcal\,mol ^{-1}\end{matrix}$ Thus HF is most stable while HI is least stable.

Thermal stability order of CaO2 SrO2 BeO2. Write the order of thermal stability of the hydrides of Group 16 elements. The solubilities of the hydroxides in water follow the order: Be(OH)2 < … Thermal stability of carbonates increases in a group as we move from top to bottom & decreases in a period as we move from left to right. In other words, as you go down the Group, the carbonates become more thermally stable. asked Apr 11, 2018 in Chemistry by Golu (106k points) p - block element +1 vote. The oxides of calcium, strontium, and barium are basic and the hydroxides are strongly basic. The thermal stability order of hydroxides is said to be increasing down the group. The salt containing one or more atoms of oxygen such as oxides ,hydroxides ,carbonate ,bicarbonate ,nitrite ,nitrate ,sulphates ,oxalates and phosphates are called oxo salts. The correct order of increase thermal stability of {K_2}C{O_{3,}}MgC{O_{3,}}CaC{O_3} and BeC{O_3} is M g(OH)2. The correct order of the thermal stability of hydrogen halides (H–X) is. 1 answer. HF > HCl > HBr > HI. As we move down the group in hydrogen halides the thermal stability decreases due to decrease in bond strength.So the correct order of thermal. ... To compensate for that, you have to heat the compound more in order to persuade the carbon dioxide to break free and leave the metal oxide. i.e. (A) MgSO4 < SrSO4 < BaSO4 : Thermal stability order. 34.6k VIEWS. Dec 29,2020 - Which is the correct thermal stability order for H2E (E = O, S, Se, Te and Po)?a)H2S < H2O < H2Se < H2Te < H2Pob)H2O < H2S < H2Se < H2Te < H2Poc)H2Po < H2Te < H2Se < H2S < H2Od)H2Se < H2Te < H2Po < H2O < H2SCorrect answer is option 'C'. This is due to a decrease in the bond dissociation enthalpy (H-E) of hydrides on moving down the group. Generally increases down the group. Sodium forms peroxides(M2O2) one Oxygen needs one sodium.
