1. In the chemical reaction shown below, the reactants are best classified as- 2H2 + O2 → 2H2O​

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.

explanation:

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

i think it's c. if you look search electronic symbol on google and then click on wiki it shows you a

i think it's letter a.
