One mole of Ag2CO3is strongly heated in an open vessel. Residue wll be...
Oxides of the metals are decomposed to metals if in electro chemical series , Eored > 0 .7 9 V
For A g, E°Ag+/Ag = 0.80 V hence Ag2O is decomposed to metals. Products are Ag , CO2 and O2. Since reaction takes place in an open vessel, CO2 and O2 escape from mixture, residue being 2 moles of silver.

One mole of Ag2CO3is strongly heated in an open vessel. Residue wll be...
Explanation:
When one mole of Ag2CO3 is strongly heated in an open vessel, it decomposes into its individual components - Ag2O and CO2. The balanced chemical equation for this reaction is as follows:

2Ag2CO3 → 4Ag + 2CO2

Let's analyze the reaction to understand why the correct answer is option 'B' - 2 moles of Ag.

Analysis:
1. Ag2CO3 decomposes into Ag2O and CO2:
- The coefficient in front of Ag2CO3 is 2, which means that 2 moles of Ag2CO3 decompose.
- According to the balanced equation, for every 2 moles of Ag2CO3, 4 moles of Ag are produced.
- Therefore, the moles of Ag formed will be twice the moles of Ag2CO3 used.

2. Residue formed:
- Since the reaction takes place in an open vessel, the CO2 gas generated will escape into the surroundings.
- Only the solid residue, Ag2O, will remain in the vessel.
- Therefore, the residue will be Ag2O.

Conclusion:
Based on the analysis, when one mole of Ag2CO3 is strongly heated in an open vessel, the residue obtained will consist of 2 moles of Ag2O (option 'B').

Read the following text and answer the following questions on the basis of the same:Microwave oven:The spectrum of electromagnetic radiation contains a part known as microwaves. These waves have frequency and energy smaller than visible light and wavelength larger than it. What is the principle of a microwave oven and how does it work ? Our objective is to cook food or warm it up. All food items such as fruit, vegetables, meat, cereals, etc., contain water as a constituent. Now, what does it mean when we say that a certain object has become warmer? When the temperature of a body rises, the energy of the random motion of atoms and molecules increases and the molecules travel or vibrate or rotate with higher energies. The frequency of rotation of water molecules is about 2.45 gigahertz (GHz). If water receives microwaves of this frequency, its molecules absorb this radiation, which is equivalent to heating up water. These molecules share this energy with neighbouring food molecules, heating up the food. One should use porcelain vessels and non metal containers in a microwave oven because of the danger of getting a shock from accumulated electric charges. Metals may also melt from heating. The porcelain container remains unaffected and cool, because its large molecules vibrate and rotate with much smaller frequencies, and thus cannot absorb microwaves. Hence, they do not get eaten up. Thus, the basic principle of a microwave oven is to generate microwave radiation of appropriate frequency in the working space of the oven where we keep food. This way energy is not wasted in heating up the vessel. In the conventional heating method, the vessel on the burner gets heated first and then the food inside gets heated because of transfer of energy from the vessel. In the microwave oven, on the other hand, energy is directly delivered to water molecules which are shared by the entire food.Q. In the microwave oven,
