The answer is elements gain electrons. Oxidation reduction is elements lose electrons. And oxygen is added/lost can be a type of oxidation/reduction reaction.
You need to look at the electronegativity and decide wheter the difference of both of the numbers are significant enough to form a polar bond
C. CaCl2 is the correct answer
Answer: they say death is painful but youve already died so i guess not that painfu;
Explanation:
This answer to this question is a rule that is applied to any reaction taken at dynamic equilibrium, with respect to 500 K. In other words, you can say that this reaction is of no use to us -
In a chemical equilibrium, it is known that the forward and reverse reactions occur at equal rates. At this point the concentrations of products and reactants remain constant, or in other words do not change
