Answer:
hydrogen ions
Explanation:
because acid is the specie that have ability to donate proton or forming bond with electron pair
The fusion on water is an enxothermic change but at this temp, the temp-entropy product is outweighed by the change in enthalpy.
Given by the name of these compounds, they are formed if one or more hydrogen atoms are substituted for halogens
X = Cl, Br, I, F
Answer:
Option a is the right one
Explanation:
Redox reactions are defined as the reactions where one element is oxidized (so the oxidation state is increased); and another element is reduced (oxidation state decreases). These changes in the oxidations states are defined by a transference of electrons.
When the oxidation state decrease → reduction → the element gains electrons
When the oxidation state increase → oxidation → the element release electrons
