Explain how the terms oxidation and reduction apply even when there is only a partial shift of electrons between atoms linked by
aliina [53]

Explanation:

In a covalent bond, there is sharing of the donated electron by two atomic species having very small electronegative differences between them.

Oxidation is the loss of electrons by a specie and it usually lead to an increase in oxidation number.

Reduction is the gain of electrons by a specie. It leads to a lower oxidation number.

Since there is no actual loss of gain of electrons in a covalent body, the electronegativiy is at work.

Electronegativity is the ability of a specie to draw the shared electrons more to itself in a covalent bond.

  • Between two atoms bonded covalently, the more electronegative specie draws the electrons closer.
  • This leaves a partial negative charge on it.
  • The other electron then becomes partially positively charged.
  • We can then say, the more electronegative specie undergoes reduction.
  • The less electronegative one undergoes oxidation.

Which describes the variable that is changed to test the prediction
slavikrds [6]

D)independent

Explanation:

An independent variable is a variable that is changed to test the prediction in an experiment. Independent variables are the cause in an experiment. They are the ones that produces the effect.

  • Changing independent variables produces different effects in an experiment.
  • These effects are the dependent variables
  • Independent variables do not depend on the outcome of the experiment.
  • They are the ones that determines how a reaction proceed and what might likely happen.
