Without knowing the specific reaction being referred to, it is difficult to provide a detailed classification. However, reactions can generally be classified as redox reactions, precipitation reactions, acid-base reactions, or decomposition reactions based on the changes that occur during the reaction process.
Sometimes, as during oxidation reactions oxygen is either added or hydrogen is removed from that particular element or compound undergoing the reaction. Combustion is burning taking place in the presence of oxygen so when the certain substance burns it is having oxygen added to it. Eg. 2Mg + O2 gives 2MgO Here Mg is getting oxidised and combustion is taking place as Mg is being heated in the presence of Oxygen.
They both occur simultaneously in a redox reaction.
The reaction between potassium metal and fluorine gas is a redox reaction. Potassium transfers an electron to fluorine, forming potassium fluoride. This reaction is highly exothermic and produces a bright flame.
Assuming that the intended reaction is BaCl2 (aq) + Na2SO4 (aq) => 2 NaCl (aq) + BaSO4 (s), this is not a redox reaction. Instead it is an ion interchange reaction, driven by the fact that BaSO4 is much less soluble in water than any of the other ions pairs barium chloride, sodium chloride, and sodium sulfate.

0.34 - (-2.37) you're welcome.
The overall voltage for the non-spontaneous redox reaction between Mg and Cu can be calculated by finding the difference in standard reduction potentials between the two half-reactions. The standard reduction potentials for Mg and Cu are -2.37 V and 0.34 V, respectively. Therefore, the overall voltage would be (-2.37 V) - (0.34 V) = -2.71 V.
-2.37 - 0.34
No, single displacement and double displacement reactions are not always redox reactions. Redox reactions involve electron transfer between reactants, while single displacement and double displacement reactions do not always involve the transfer of electrons.
The overall voltage for the redox reaction involving Ag and Cu is determined by subtracting the reduction potential of the anode from the reduction potential of the cathode. Given the reduction potentials of Ag and Cu as 0.80 V and 0.34 V respectively, the overall voltage is 0.46 V, calculated as (0.34 V) - (0.80 V).
The overall redox reaction of Cr2O7 + Br is not a balanced equation. To balance the equation, the half-reactions for the oxidation and reduction of each element need to be determined and balanced first.
Single displacement reaction and a double displacement reaction are redox reactions. apex- false
To determine the overall voltage for the redox reaction involving the half-reactions ( \text{Mg}(s) \rightarrow \text{Mg}^{2+} + 2e^- ) and ( \text{Cu}^{2+} + 2e^- \rightarrow \text{Cu}(s) ), you first need the standard reduction potentials. The standard reduction potential for ( \text{Cu}^{2+}/\text{Cu} ) is +0.34 V and for ( \text{Mg}^{2+}/\text{Mg} ) is -2.37 V. The overall voltage is calculated by subtracting the oxidation potential of magnesium from the reduction potential of copper: ( 0.34 , \text{V} - (-2.37 , \text{V}) = 2.71 , \text{V} ). Thus, the overall voltage for the redox reaction is 2.71 V.
Yummy, Chemistry :) Redox reactions - Oxidation reaction This is a reaction in which atoms have undergone a change in their oxidation state.
