Answer:
a) 0
Explanation:
Each of the small dots surrounding the C1 represents one electron. These are where electrivity comes from. Since there is the same number of electrons in both atoms, the difference is 0 (because 6 electrons-6electrons= 0).
Answer : If an increase in temperature accompanies a reaction, energy is released. Explanation :In thermodynamics, the reaction is considered as a system and the medium in which the reaction occurs which is usually an aqueous medium is considered as its surrounding. When the heat flows from the system to its surrounding, it increases the temperature of surrounding medium because the heat released by the system is absorbed by its surrounding. This is known as exothermic reaction. An exothermic reaction is always accompanied by energy release. On the other hand, when the heat flows from the surrounding towards system, it decreases the temperature of the surrounding medium. This is known as endothermic reaction. From the above discussion we can say that If an increase in temperature accompanies a reaction, energy is released.
Good luck ;)
All chemical reactions involve energy. Energy is used to break bonds in reactants, and energy is released when new bonds form in products. Endothermic reactions absorb energy, and exothermic reactions release energy. The law of conservation of energy states that matter cannot be created or destroyed.
As waves reach the shore, the energy in front of the wave slows down due to friction with the shallow bottom. ... The wave breaks, and it usually does so in water depth that is 1.3 times the wave height.
