Which balanced equation represents an oxidation-reduction reaction?
Equations that separate the oxidation from the reduction parts of the reaction
Does Oxidation and reduction reactions occur at the same time?
Yes, an element can undergo both oxidation and reduction in the same reaction. The reaction between Zinc and Copper Sulphate is a perfect example. This type of reaction is called a redox reaction.
Why is oxidation and reduction processes are complementary?
Oxidation is loss of electrons. Reduction is gain of electrons.Therefore in a redox reaction one substance will lose electrons which the other picks up and gains.So the complimentary part is because in order for one substance to gain electrons another in the system must be losing them.I think that is what is meant - although it has been many years indeed!-from von2 posadas of EN 4A UE Caloocan
Undergo no chemical change during a chemical reaction?
A catalyst doesn't undergo a chemical change during a chemical reaction.
Is mixing calcium chloride and water a chemical reaction?
Yes. CaCl2(aq) + H2O(aq) = 2HCl(aq) + CaO(s), a double displacement reaction which forms a precipitate, therefore, is a chemical reaction.
Is it possible to have a reaction in which oxidation takes place but reduction does not?
Oxidation is characterized by the loss of electrons, and reduction is characterized by the gain of electrons. Since there must be an electron loser and an electron receiver, oxidation and reduction are always complimentary.
What reaction is reduction?
In chemistry, reduction is considered the gaining of electrons. Oxidation is the lose of electrons. They go together in reactions called redox (reduction/oxidation). You cannot have a reduction without also having an oxidation.
Oxidation cannot occur without?
Oxidation cannot occur without a reduction reaction happening simultaneously. In a redox reaction, electrons are transferred between two species: one is oxidized (loses electrons) and one is reduced (gains electrons). This electron transfer process is essential for oxidation to take place.

What can oxidation not occur without?
Oxidation cannot occur without a reduction reaction happening simultaneously. In a redox reaction, one reactant is oxidized (loses electrons) while another is reduced (gains electrons). This transfer of electrons is essential for oxidation to take place.
Does Oxidation and reduction reactions occur at the same time?
Yes, an element can undergo both oxidation and reduction in the same reaction. The reaction between Zinc and Copper Sulphate is a perfect example. This type of reaction is called a redox reaction.
The following reaction takes place in an acidic solution. MnO4–(aq) + Cl–(aq) Mn2+ + Cl2(g) (unbalanced) Write the reduction and oxidation half-reactions (without electrons). :(?
Reduction Half-Reaction: MnO4-(aq) → Mn2+(aq) Oxidation Half-Reaction: Cl-(aq) → Cl2(g)
Does removing oxygen always prevent an oxidation recreation?
Removing oxygen does prevent oxidation from occurring since oxidation is a chemical reaction that involves the gain of oxygen by a substance. Without oxygen present, oxidation cannot take place.
Why must oxidation and reduction occur simultaneously?
Because for oxidation to take place the electrons lost by the substance that is oxidized must be accepted by atoms or ions of another substance. Also, for reduction to occur the electrons gained by the substance that is being reduced must be transferred from the atoms of ions of another substance. Therefore, oxidation and reduction are complementary processes: that is to say that oxidation cannot occur without reduction and visa versus.
Why IS OXIDATION DESCRIBED AS A OXIDATION REACTION?
Oxidation is described as an oxidation reaction because it involves the loss of electrons from a substance, leading to an increase in its oxidation state. This process often occurs alongside reduction, where another substance gains those electrons. Commonly associated with reactions involving oxygen, oxidation can also occur in scenarios without oxygen, emphasizing its broader definition related to electron transfer rather than just the presence of oxygen. Thus, an oxidation reaction is fundamentally about changes in electron distribution and oxidation states.
What is meant by Auto-redox reaction?
An auto-redox reaction, also known as an autooxidation-reduction reaction, is a chemical reaction where a substance is both oxidized and reduced by itself. This type of reaction involves the transfer of electrons within the same chemical species, leading to the formation of new products without the presence of an external oxidizing or reducing agent.
Is oxidation an example of mechanical weathering?
no. oxidation is a chemical reaction that involves an atom or a molecule losing electrons in a chemical reaction. Mechanical weathering would be something like water seeping into cracks in a rock, then freezing and breaking that rock apart.
