Answer:
Middle: Self heating containers are really expensive but are useful because they are easy to use, portable, and can be recycled, unlike a camp stove which is not as easily moved.

Explanation:
Temperature is defined as a measure of the average kinetic energy of the molecules of a body.
When a substance is heated, the kinetic energy of its molecules increases as the temperature increases; hence the particles of the substance moves faster with increasing temperature.
When heat is withdrawn from a liquid, the temperature decreases and the average kinetic energy of the molecules decreases. The molecules become less energetic hence the liquid changes into solid
Answer:
In this chemical reaction, which is considered irreversible, that is why the reaction arrow is ONE and unidirectional and not two in opposite directions, which means reversibility of the reaction.
In summary, if we look closely at the reaction, we observe that the stoichiometric values are balanced in the reaction, therefore there is THE SAME AMOUNT OF REAGENTS AS PRODUCTS.
This phenomenon has to be met in ALL CHEMICAL REACTIONS, the stoichiometric balance is essential for this reaction to be well expressed.
Why is stoichiometric balance so important? Why we indicate that we have the same amount of reagents as products, means that NOTHING IS LOST, EVERYTHING IS TRANSFORMED in the matter of the organic compounds that reacted.
Explanation:
Although if we observe the stoichiometric values well they are not correct with respect to oxygen, therefore it would be necessary to correct that in the chemical reaction, but above we briefly explain why the balancing of the reactions and the relationship they have with the conservation of the mass.
The law of conservation of mass indicates that mass is never lost, but is transformed, like energy, considering that it happens in terrestrial life.
Ice is less dese than water
The answer is (3). The reaction that can occur at the anode is oxidation reaction which will lose electrons. So (1) and (2) are not correct. For (4) Fe3+ can not lose electrons again.
