answered-by-expert Expert Answer

(a) The reactions in which one reactant gets oxidized while the other gets reduced during the reaction are called oxidation-reduction reactions or redox reactions.

(b) The reaction between manganese dioxide and hydrochloric acid is a redox reaction because MnO2 is reduced to MnCl2 and HCl is oxidized to H2O.

 MnO2 + 4HCl → MnCl2 + Cl2 + 2H2O

(c) Oxidizing agent - HCl Reducing agent - MnO2

water is in the form of H2O, and from the equation it is clear that concentration of hydrogen is more in water, since, thier are 2 atoms of hydrogen in a single molecule, my main question was, why water is not flammable? as liquid version of hydrogen is used as fuel in space shuttle, which is combined with oxygen, and in water, both are present. Please reply. I am having this doubt from long time.
