What happens when you burn magnesium metal using the big idea of energy?
I wonder what your teacher thinks is the big idea of energy?
To me, it is that "matter and energy are equivalent, and may be interchanged with each other in transformation, but the sum total of energy and mass equivalent is constant in the universe"
That is indeed a big idea.
So within that big idea, if magnesium "burns", and give off heat, some of its mass (albeit many billionths of a nanogram) has changed into energy.
I suspect your teacher has a lessor big idea, and I have no clue.
i have this aswell... we havent learned about it or anything.. it just says, 'explained the big idea of energy' wtf is this
When you burn magnesium metal, a chemical reaction takes place known as combustion. This reaction involves the release of energy in the form of heat and light. Magnesium metal reacts with oxygen gas in the air to form magnesium oxide.
Now, let's dive into the big idea of energy that applies to this scenario: the Law of Conservation of Energy. According to this law, energy cannot be created or destroyed, but it can be transferred or converted from one form to another.
In the case of burning magnesium, the energy is initially stored in the chemical bonds of the magnesium atoms and the oxygen molecules. As the reaction occurs, the heat energy from the surroundings breaks the bonds between the magnesium and oxygen atoms. This process requires energy, which is absorbed from the surrounding air or heat source.
Once the initial energy is supplied to start the reaction, a significant amount of heat energy is released. The energy released by the reaction is in the form of heat and light, causing the brilliant white light and intense heat associated with burning magnesium. The energy released is the result of the magnesium and oxygen atoms forming new bonds to create magnesium oxide.
In summary, when you burn magnesium metal, the chemical reaction releases the energy stored in the chemical bonds. This energy is converted into heat and light, following the Law of Conservation of Energy.
