Answer:positive electrode
Explanation:
Anode can also be referred to as positive electrode in a cell
The balanced half-reaction: Cr²⁺⁺(aq) → Cr⁴⁺(aq) + 2e⁻.
Chromium(II) cations two electrons and became chromium(IV) cations.
<span>Oxidation
reaction is increasing of oxidation number of element, because element or
ion lost electrons in chemical reaction.
</span><span>Reduction is lowering
oxidation number because element or ions gain electrons.</span>
The chemical bonds in CH4 are all single bonds. C only can bond 4 times because it needs 8 electrons in it's outer shell and only has four right now. The bonds represented are all single bonds because there are two electrons present on each side of the carbon. Two electrons, in this case, equals one bond.
Each substance has its own unique structure and properties that are based on these structures.
One of those most important properties is the "specific heat" value.
Specific heat is defined as the amount of heat required to raise the temperature of a unit mass of a substance by 1 degree Celsius.
Each substance has its own specific heat. The higher the specific heat of a substance, the longer it will take to heat up or cool down.
Hope this helps :)
