no, it contains 3 basic particles. (protons, electrons, neutrons)
hope this helped
A chemical change is one where the compounds are modified: a compound decomposes into its elements, or combine with other elements to form a different compound.
That is what happens when a match burns: oxygen reacts with the match compounds and form CO2(g), H2O(g) and other compounds depending on the composition of the match.
The other processes only involve a physical change of the compounds, but they remain being the same compounds (same elements with the same bonds).
Answser: option 1. the burning of a match.
The excess reactant is Aluminum.
<u>Explanation:</u>
We have to write the balanced equation as,
4 Al+ 3 O₂ → 2 Al₂O₃
According to the molar ratio 4: 3, from the given balanced equation, we can say that 4 atoms of Al reacted with 3 molecules of oxygen.
Given that 10 atoms of aluminum reacts with 6 molecules of oxygen, as per the ratio only 8 atoms of Aluminum is required to react with 6 molecules of oxygen, so excess reactant is Aluminum.
