<h3>Balancing equations</h3>
In order for equations to be balanced, the component atoms in the reactants and products must be the same in terms of number.
Thus, in the given equation, the number of H, N, O, and Ba atoms in the reactants and the products must be equal.
Therefore, the overall equation becomes:

Answer:
Explanation:
The nuclear model of the atom was suggested by Ernest Rutherford based on his experiment on a thin gold foil.
To explain his observations, he suggested the atomic or nuclear model.
In this model, the atom has a small positively charged center called the nucleus.
All the mass of the atom is concentrated here in the nucleus.
Surrounding the nucleus is a large space
It is the extranuclear part
This part contains electrons.
A nucleus surrounded by electrons forms the nuclear model of the atom.
D, obviously. All living things are made of one or more cells, therefore non-living things aren’t made of cells
