sorry to annoy anyone, but WHAT is the big idea of energy? i would really appreiciate a response
In what context? Too much use. Not reneewable? Cost? availability?
in the context of an ironsulphide reaction
I still don't understand the question.
explaining the iron/sulphur reaction 'using the big idea of energy'
explaining the iron/sulphur reaction 'using the big idea of energy'
i need to explain the iron/sulphur reaction using the big idea of energy, no one i know understands this.
mmmeeeeeeeee to i rly don't get it, oh gosh and mi test is ment to be in tomoz HHHEEELLLPP MMMMEEEEE...(mutters "stupid big idea of energy")
the big idea of enery... um... don't know anything sorry.
don't know anything
Well it's when you mix stuff together to make poop
i like poop
The "big idea of energy" refers to the fundamental concept of energy and its various forms, transfers, and transformations. In the context of the iron/sulphur reaction, understanding the big idea of energy involves recognizing and explaining the energy changes that occur during the reaction.
To explain the iron/sulphur reaction using the big idea of energy, you need to consider the energy changes before, during, and after the reaction. Here's a step-by-step explanation:
1. Initial energy state: At the beginning of the reaction, both iron and sulphur are in a stable state with a certain amount of potential energy. This potential energy is stored within the chemical bonds of the reactants.
2. Activation energy: To initiate the reaction, an input of energy is needed to overcome the activation energy barrier. This additional energy allows the reactants to break their existing bonds and facilitates the formation of new ones.
3. Reaction and energy transfer: Once the activation energy is supplied, the iron and sulphur atoms start to combine and form iron sulphide. This chemical reaction involves a rearrangement of atoms and the formation of new bonds. As the reaction proceeds, energy is both released and absorbed.
4. Exothermic and endothermic processes: The energy released or absorbed during a chemical reaction can be categorized into two types: exothermic and endothermic. An exothermic process releases energy in the form of heat or light, while an endothermic process absorbs energy from the surroundings.
5. Energy change in the iron/sulphur reaction: In the case of the iron/sulphur reaction, it is an exothermic process. This means that more energy is released during bond formation in the iron sulphide molecules than is required to break the bonds in the reactants. As a result, the overall energy of the system decreases, and the excess energy is released as heat or light.
6. Final energy state: After the reaction is complete, the iron and sulphur have transformed into iron sulphide, and the system has reached a new stable state with lower potential energy compared to the initial state.
In summary, the big idea of energy helps us understand and explain the changes in energy that occur during the iron/sulphur reaction. It involves considering the initial energy state, activation energy, energy transfer during the reaction, classifying the process as exothermic, and understanding the final energy state.
