Answer: 
, 
and 
are formed at the end of the reaction. They are named as tin (IV) oxide or stannic oxide, nitrogen dioxide and water respectively.
Explanation: Reaction of tin and nitric acid is given as:
Three products are formed at the end of the reaction which are:
- which is termed as stannic oxide or Tin (IV) oxide. This is a white colored solid.
- which is termed as nitrogen dioxide. These are brown colored fumes.
- which is termed as water.
At the starting tin was a silvery-white colored solid and after the reaction, it changed the color to milky-white. This change in color is due to the chemical reaction happening between tin and nitric acid.
Release of brown fumes are also an indication that a chemical reaction has taken place.
The <u>option which correctly compares beta decay and gamma decay</u> is Beta-decay releases a particle, while gamma decay only reduces the energy level. Beta-decay is a form of nuclear fission, but gamma decay is not.
Beta decay is a form of radioactivity in which an electron is released. The electron could be positively charged(positron) or negatively charged.
Also, beta decay also occurs when there is nuclear fission of a substance in which a larger atom breaksdown into a smaller atom and releases energy.
Gamma decay is a form of radioactivity in which photons are released without the release of a particle from the atom.
Since a photon is released, only the energy level of the atom reduces and is thus not a form of nuclear fission
So, the <u>option which correctly compares beta decay and gamma decay</u> is Beta-decay releases a particle, while gamma decay only reduces the energy level. Beta-decay is a form of nuclear fission, but gamma decay is not.

Answer:
In a redox reaction, hypochlorite ion would be more easily reduced.
Explanation:
Hypochlorite compounds are generally unstable - e.g. sodium hypochlorite is not available in solid form, because removing water from a NaClO disolution, causes a dismutation, turning it in a mixture of NaCl y NaClO3. Heating the same disolutions will also cause this effect. Hypochlorite will decompose under solar light into chlorides and oxygen.
Due to their low stability, hypochlorite compounds (i.e. those containing the hypochlorite ion) are very strong oxidants. Perchlorate ion can balance its negative charge instead and thus will be less prone to reduction than hypochlorite.
