An atom cannot receive an electron (be reduced) without another atom giving up an electron (be oxidized). In other words, it's impossible to have just a reduction because another atom needs to first give the electron up.
The single elements in the reactants will have oxidation numbers of 0. Once they are in a compound, they will have different oxidation numbers.
Not all combination reactions are redox reactions. If all the reactants are compounds, then they will not be redox reactions. For example:
CaO + SO2 --> CaSO3
Balancing redox reactions is different from balancing other reactions because both the number of atoms and the amount of charge must be balanced.
If one substance is losing electrons (where it is gaining charge, or oxidizing), we must assume those electrons are going to another substance in the reaction, which will cause the charge to go down, or reduce. This type of equation is called a Redox (reduction-oxidation) reaction.

Not technically. A neutralization reaction is the correct answer. NaOH + HCl --> NaCl + H2O Products of a neutralization reaction; a salt and water. In a redox reaction something must be oxidized and something must be reduced and oxidation states must be changed, so I am not too sure that is happening here.
Hydrogen ion (acid) has extra electrons which can be donated so the reaction can take place, whereas oxygen can accept those ions to form water in the product. That's why redox reactions always start of in a acidic solution and end up in a neutral/basic solution.
The most important thing to consider is the number of electrons being transferred. Of course one also must consider the mass on each side of the equation.

An acid and an alkali/base takes place in a neutralization reaction. For reactions such as redox, precipitation etc. an acid or a base might not take place.

electrons must be transfered from one atom to another

we must classify its human nature to organize. and also to predict
to be a welder you must have very steady hands and good eye focus also you must know what process you are doing and what the reactions of this process are

yes it does because if it is an redox reaction then something has to be getting reduced of oxygen, therefore the equation must contain oxygen in some type of form somewhere. Sorcha :)
Biochemical reactions in the body must occur in solution; otherwise, they cannot chemically react.
