Both oxidation and reduction
1- Reaction of an acid with a base. 2-Displacement reactions of ionic compounds.
Oxygen gas is neither a physical nor a chemical property. It is a state. The property of being a gas is a PHYSICAL property, however.
Darkness means no reduction. NADP is in light reactions - DPIP is electron acceptor susbstitute for NADP... if NADP does not react in darkness (plants dont react at night and do not undergo photosynthesis) then neither should DPIP
no
During a chemical reaction matter is neither created nor destroyed
It is neither oxidation nor reduction it is simply a double displacement reaction.
It's not entirely clear what the question is asking... but oxidation involves the loss of electrons from an atom or ion, and reduction involves the gain of electrons. The other parts of a redox (reduction-oxidation) reaction may involve atoms forming and breaking bonds, but the oxidation or reduction part is just about losing or gaining electrons. You might be talking about what is called a "half-reaction." A half-reaction is the part of the reaction that is only either the oxidation step or the reduction step. Neither is a complete reaction, but put together the two half-reactions give the overall reactions. In the oxidation half-reaction, electrons come out as products, and in the reduction half-reaction electrons go in as reactants. Remember: OIL RIG Oxidation Is Loss; Reduction Is Gain.

Oxidation
whether oxidation, reduction or neither has occured.
A. Fe^2+ ==> Fe^3+ + e- is an oxidation reactionB. Fe^3+ +e- ==> Fe^2+ is a reduction reactionC. Fe(s) ==> Fe(l) is neither an oxidation nor a reduction reaction. It is a phase change.D. Fe + 2e- ==> Fe^2+ is not a possible reaction.
It is safer to claim it as neither - not least because the reaction would/does not work. Far safer to say that the sulphur is oxidised (which, you could argue, makes it a reducing agent).
Fermentation is not considered as an oxydation reaction. ------------------------------------------------------------------ It may not usually be considered as such, but the oxidation state of C in sugar is zero, and the oxidation state of C in ethanol is -2. Any change in oxidation state can be treated as a redox process. Loss of electrons (or an increase of oxidation state) is oxidation, gain of electrons (or a decrease of oxidation state) is reduction. The carbon that ends up in the ethanol has decreased its oxidation state from 0 to -2 so those atoms have undergone reduction. Reduction cannot exist without a subsequent oxidation, so something else has undergone oxidation. The fermentation process also makes carbon dioxide. The C in those molecules has an oxidation state of +4, so those atoms of carbon have been oxidized. So the answer is --- both.
Oxygen gas is neither a physical nor a chemical property. It is a state. The property of being a gas is a PHYSICAL property, however.
The way to tackle this to look at reactants and at the products, and this where oxidation numbers come in. Remembering that oxidation is loss of electrons and reduction is gain, (OILRIG is an acronym that is sometimes used). Mn metal is changed to Mn2+ so it is oxidised H in HCl has a +1 oxidation number and in H2 zero so it is reduced. Cl in HCL is at -1 and is -1 in MnCl2 so it is neither oxidised nor reduced.
Neither. A Net Loss is a reduction of Equity.
In any chemical reaction atoms are neither created nor destroyed.
