I would say that the main purpose of the European Union is to strengthen the economy of the member states by merging their economies and by introducing one stronger, common economy - a stronger economy for the states means a better comfort of life in those states.

Answer:
The atoms or molecules bond closer together.
Explanation:
The gas molecules are free and float around whereas liquid atoms are bonded but are able to move freely as long as they are touching each other. These two substances are different to a solid substance because the molecules or atoms will not not be tightly bound together.
It is True, oxidation is associated with an increase in oxidation number.
An oxidation; reduction or redox reaction is a reaction that involves the transfer of electrons between chemical species (the atoms, ions, or molecules involved in the reaction). Redox reactions are all around us: the burning of fuels, the corrosion of metals, and even the processes of photosynthesis and cellular respiration involve oxidation and reduction. Oxidation states are typically represented by integers which may be positive, zero, or negative.
The term oxidation was first used by Antoine Lavoisier to signify the reaction of a substance with oxygen. Much later, it was realized that the substance, upon being oxidized, loses electrons, and the meaning was extended to include other reactions in which electrons are lost, regardless of whether oxygen was involved.
