The formula H4N2O3 represents a salt containing ammonium (NH4+) and nitrate (NO3-) ions. These ions are often present in fertilisers because they effectively deliver nitrogen to plants.
The empirical formula H4N2O3 represents a salt used in fertilisers and it contains hydrogen, nitrogen, and oxygen. In this salt, the ions present are the ammonium ion (NH4+) and the nitrate ion (NO3-). Hydronium and nitrogen dioxide might also be present in the compound. However, the most relevant ions are generally the ammonium and the nitrate ions, because they are often used in fertilizers due to their abilities to effectively deliver nitrogen to plants.

Photosynthesis
Answer:
The correct option is: D. Photosynthesis
Explanation:
Photosynthesis is a biological process in green plants by which food such as sugar (like glucose C₆H₁₂O₆), is synthesized from water (H₂O) and carbon dioxide (CO₂) from the atmosphere, in the presence of light energy. This process produces oxygen gas (O₂) as a by-product.
This reaction converts the light energy from the sun to chemical energy.
The reaction involved is: 6 CO₂ (g) + 6 H₂O + light → C₆H₁₂O₆ (s) + 6 O₂ (g)
Photosynthesis is the only process among the given options, that produces oxygen gas.
(2) geothermal energy (4) nuclear energy
(2) 200. K to 400. K (4) 200.°C to 400.°C
(2) emitted by the electron
(3) absorbed by the nucleus
(4) absorbed by the electron
An atom of oxygen is in an excited state. When an electron in this atom moves from the third shell to the second shell, energy is emitted by the electron. Hence, option B is correct.
The smallest piece of stuff that still retains its characteristics is an atom. A gold atom, for instance, is the smallest piece of that element that will still retain all of gold's properties and behaviors. When an atom is disassembled into its component parts, the subatomic particles found inside each have special characteristics that are not at all similar to those of the element the atom represents. Protons, neutrons, and electrons are the three different subatomic particle kinds.
The electron that transitioned from a higher to a lower level felt the change in energy level. Since the nucleus is unaffected, its energy levels are unaffected as well. Since it requires more energy to keep an electron at a higher energy level than a lower one, the shift in energy levels indicates that the electron released some energy.
