Classify this chemical reaction 2Cu plus O2 2CuO plus 315kj?
This is an exothermic reaction because it releases energy (315 kJ), indicating that it is spontaneous and gives off heat. The reaction involves the oxidation of copper (Cu) by oxygen (O2) to form copper oxide (CuO).
Which reaction are of oxidation reaction and are of exothermic nature?
These are not mutually exclusive. A reaction can be oxidation and exothermic. Oxidation reactions involve a change in oxidation state (charge) which is interpreted as a loss of electrons. Exothermic reactions release heat energy.
Is oxidation endothermic?
An oxidation reaction is also known as a redox reaction. Not all redox reactions give off heat. Some redox reactions give off heat and some require heat from an outside source for the reaction to be completed.
Copper oxidation number?
It depends on the compound. +1 and +2 are the more common ones (as in Cu2I2 and CuI2 respectively). In elemental form, its oxidation number is zero.
Difference between cucl and cu2cl2?
CuCl is copper (I) chloride, where copper has a +1 oxidation state. Cu2Cl2 is copper (II) chloride, where copper has a +2 oxidation state. The difference lies in the oxidation state of copper present in the compounds.
Is oxidation of copper exothermic or endothermic?
Copper oxidation is endothermic.

Is oxidation a exothermic or endothermic reaction?
it is exothermic b/c it gives off heat

Is copper exothermic or endothermic?
Copper is neither exothermic nor endothermic. Exothermic and endothermic describe reactions that release or absorb heat, respectively. Copper itself does not undergo a reaction that releases or absorbs heat, so it does not fall into either category.
Is paint drying exothermic?
As paint dries through the process of oxidation the reaction produces heat, which is an exothermic reaction.
What is the oxidation state of cupric ion in copper tartar-ate?
The oxidation state of the cupric ion in copper tartarate is +2. Copper (II) ion, or cupric ion, has an oxidation state of +2 due to the loss of 2 electrons. In the case of copper tartarate, the ligand (tartarate) does not affect the oxidation state of the central copper ion.
Copper oxidation number?
It depends on the compound. +1 and +2 are the more common ones (as in Cu2I2 and CuI2 respectively). In elemental form, its oxidation number is zero.
Why does liver and hydrogen peroxide exothermic?
Hydrogen peroxide is an oxidising agent, and oxidation is an exothermic reaction. The liver is being oxidised.
What Kinds of chemical changes?
Exothermic reactions. E.g. combustion, oxidation
Difference between cucl and cu2cl2?
CuCl is copper (I) chloride, where copper has a +1 oxidation state. Cu2Cl2 is copper (II) chloride, where copper has a +2 oxidation state. The difference lies in the oxidation state of copper present in the compounds.
