Thermal stability of $\mathrm{BaCO}_{3}, \mathrm{CaCO}_{3}$ and $\mathrm{MgCO}_{3}$ is (a) $\mathrm{BaCO}_{3}>\mathrm{CaCO}_{3}>\mathrm{MgCO}_{3}$ (b) $\mathrm{BaCO}_{3}>\mathrm{MgCO}_{3}>\mathrm{CaCO}_{3}$ (c) $\mathrm{MgCO}_{3}>\mathrm{CaCO}_{3}>\mathrm{BaCO}_{3}$ (d) $\mathrm{CaCO}_{3}>\mathrm{MgCO}_{3}>\mathrm{BaCO}_{3}$

In this problem, we can obtain as three or four as three Beautiful can be obtained as a product by following the accent. So just look at it carefully. When a red fast porous deactivate, Bye at 10 03 It is right When white first reported, react with kong as two and so forth. It will give us three P. 04 And when we see L. Three, the activate of the leak acid plus hit. It will give a strip your food, so option B. It correct here.

As we know that as we know that in this problem, CN group CN you do get reference, get difference over oh, it guru. Our ohh group in there, only functional in a bully functional compound. Therefore, according to the given option option C it corrected option C 205 hide job engine carbonite trial is the correct answer. I hope you understand the solution.

In this problem, I'm writing the the reaction so just look at it carefully in presence of concentrated SCL f e c l t six H two in potential concentrated SCL will give the product ad f e CL four I am. Therefore according to the given option in this problem, option A is correct, therefore absent age. But again, sir, for this problem.

In this problem, I can write the reaction age this compound Plus Cl two in Potenza. Every cl tree will give this compound here it is cl And this compound in Potenza CS three cl and hide us. LCL three will give this compound here it is. See http here it is cl plus this compound here it is. Yes terry, he irritates cl. This is peak laura tall win and this is oh claro will win. So religions are also para directing here and according to the option option, see each correct.
