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.
The correct statements about the structure of periodic table are:
1. The inner transition elements are placed at the bottom of the periodic table for easy viewing.
2. The distribution of electrons in energy levels is responsible for the shape of the periodic table.
Periodic table has more groups than periods.
And it has more metals than non metals.
Denitrifying Bacteria such as Pseudomonas aeruginosa is the type of bacteria that use enzyme nitrate reductase to metabolise nitrogen oxides to nitrogen gas.
Denitrification is the process whereby nitrites or nitrogen oxides is converted to nitrogen gas by a denitrifying Bacteria such as Pseudomonas.
Pseudomonas aeruginosa uses enzyme nitrate reductase to reduce nitrate to nitrite.
Then nitrite is then converted back to nitrogen gas.
Therefore, Pseudomonas aeruginosa is a type of bacteria that uses enzyme nitrate reductase.

How to find it- Add up the mass of protons and neutrons
The total number of atoms make up the products :
D) 1 carbon, 4 hydrogen, and 4 oxygen
<h3>Further explanation
</h3>
Complete combustion of Hydrocarbons with Oxygen will produce CO₂ and H₂O compounds.
If O₂ is insufficient there will be incomplete combustion produced by CO and H and O
Hydrocarbon combustion reactions (especially alkanes)
For combustion of methane (CH₄) and two molecules of oxygen (O₂).

The number of atoms make up the products
CO₂ : 1 carbon, 2 oxygen
2H₂O : 4 hydrogen , 2 oxygen
