An optical double is an illusion—the stars are at vast distances from each other and are not actually orbiting each other—whereas in a visual binary, the stars are actually orbiting each other. its total energy output into all space
The excess reactant in the combustion of 211 g of methane in an open atmosphere is oxygen, O₂
<h3>What is a combustion reaction? </h3>
A combustion reaction is a reaction in which a substance burns in air (oxygen) to produce carbon dioxide and water.
<h3>Combustion of methane </h3>
Methane combust in air (oxygen) to produce carbon dioxide and water according to the following equation:
CH₄ + 2O₂ —> CO₂ + 2H₂O
From the question given above, we were told that 211 g of methane combust in an open atmosphere. This simply means that the amount of oxygen will be very high.
Therefore, we can conclude that oxygen will be the excess reactant since the reaction is carried out in an open atmosphere.

- René Descartes can be regarded as one of the philosopher that brings sbout invention of analytical geometry as well as skepticism which serve as essential part of the scientific method.
- With his analytical geometry relationship between separate fields of geometry and algebra were established.
Descartes has four rules which help him to have a true conclusion about his research, and they are :
- Doubting of everything is allowed
- Every bulk problem must be broken into parts
- Solving of the simplest problem must come first.
- Be thorough.
Therefore, descartes’s rules can be regarded as essential part of scientific method
