Answer:
A nuclear reaction releases more energy per gram and appears to violate the law of conservation of mass.
Explanation:
- In nuclear reactions there arises a shift in the nucleus of the atom. This results in the production of a different element altogether. While in chemical reactions the electrons are rearrangement and there is no change in the nucleus.
- Factors like temperature, pressure, and catalysts do not affect the rate of nuclear reactions while they influence the chemical reactions.
- The change in the energy is higher in nuclear reactions. It arises out of the destruction of mass.
<span>Hey Jose! Thanks for asking a question here on Brainly.
⚪ Potassium

The answer is nosocomical.

Answer:
Nitrogen reacts with oxygen to form a number of nitrogen oxides. It exhibits different oxidation states in its oxides, ranging from +1 to +5. Oxides of nitrogen having nitrogen in the higher oxidation state are more acidic than that in lower oxidation state. Nitrogen oxides are critical components of photochemical smog. They produce the yellowish-brown colour of the smog. In poorly ventilated situations, indoor domestic appliances such as gas stoves and gas or wood heaters can be significant sources of nitrogen oxides.
Following are the harmful effects caused by the oxides of nitrogen
Nitrogen oxides causes irritation in mucous membrane.
Large concentrations of Nitrogen oxide causes lungs problems in humans
It causes injuries to vegetation by damaging leaves.
Nitrogen oxide oxidizes Hydrocarbons in the presence of sunlight, which causes eye irritation, asthama attacks, nasal and throat infections.
NO: sharp, sweet-smelling, colourless gas. Melting point: -163.6°C. Boiling point: -151.8°C. Relative Density: 1.04 (air = 1) NO2: reddish-brown gas with irritating odour
