Answer: Multiple answers to this question. This is what I comprehend.

Explanation:

Upon analysis of the results, a theory can be rejected or modified, but it can never be proven to be correct 100 percent of the time. For example, relativity has been tested many times, so it is generally accepted as true, but there could be an instance, which has not been encountered, where it is not true.

Study the following reaction carefully. What classification should this reaction have? 4Al + 3O 2 2Al 2 O 3
nikitadnepr [17]

The reaction is a synthesis…

4Al + 3O_2 \longrightarrow 2Al_2O_3\\

… because <em>two substances are combining to make one other substance</em>.

4\stackrel{\hbox{0}}{\hbox{Al}} + 3\stackrel{\hbox{0}}{\hbox{O}}_2 \longrightarrow 2\stackrel{\hbox{+3}}{\hbox{Al}}_2\stackrel{\hbox{-2}}{\hbox{O}}_3\\

It is also a <em>reduction-oxidation reaction</em> because the <em>oxidation number of Al increases</em> from 0 to +3 and the <em>oxidation number of O</em> decreases from 0 to -2.

Ilya [14]

  • The alkanes are non- polar solvents.
  • The alkanes are immiscible in water but freely miscible in other non-polar solvent .
  • The alkanes are consisting of weak dipole dipole bonds can not breaks the strong hydrogen bond.
  • The alkanes having only carbon (C) and hydrogen (H) atom which is bonded by a single bonds only.
  • The alkanes posses weak force of attraction that is weak van der waals force of attraction.

The ethane, propane, butane, belong to alkanes family.The alkanes are also considers as saturated hudrocarbons. Ethane is found in gaseous stae Ethane is the second alkane followed by propane followed by butane.
