Answer:
The reaction has a single reactant
Explanation:
Decomposition reaction is a reaction in which an insoluble single compound is heated at a high temperature and decomposes into several products.
Typically, we may see decomposition of calcium carbonate producing calcium oxide and carbon dioxide, this is represented by the following reaction:
Another example would be decomposition of ammonium nitrite. Ammonium nitrite would decompose into nitrogen and water:
Notice that the two examples above share something in common: the two decomposition reactions have a single reactant.
Lithium has 1 valence electron and chlorine has 7 valence electrons.
Answer:
B) a neutron
Explanation:
The mass of a proton is approximately the mass of a neutron.
Both a neutron and proton are nuclear particles that are found within the nucleus of an atom.
Protons are the positively charged particles within an atom.
Neutrons do not have any charges on them.
Approximately the mass of:
Protons = 1.67 x 10⁻²⁷kg
Neutrons = 1.68 x 10⁻²⁷kg
If you are asking for the electron configuration of Ne, then the naswer is 2-8.
