Answer:
Explanation: For most longer adjectives, the comparative is made by adding the word "more" (for example, more comfortable) and the superlative is made by adding the word "most" (for example, most comfortable). If a 1-syllable adjective ends in "e", the endings are "-r" and "-st", for example: wise, wiser, wisest.

Explanation:
For a reaction that proceeds by E1 mechanism, the rate determining step involves the formation of the carbocation.
The rate of formation of this carbocation depends only on the concentration of the t-butyl bromide since it is the only specie that enters into the rate equation.
Hence, when the concentration of t-butyl bromide is tripled, the rate of reaction is tripled.
Methanol does not enter into the rate equation hence doubling its concentration does not affect the rate of reaction.
Answer:
The number of moles of H₂O is 0.135 mol.
The number of moles of LiClO₄ is 0.0449 mol.
Explanation:
Mole is an important standard unit used for the measurement of large quantities of atoms, molecules, or other particles. One mole is equal to 6.022×10²³ units.
The number of moles of a substance is calculated by:
To find the number of moles of H₂O:
Mass of H₂O in the sample = 2.43g
The molecular weight of H₂O = 18.02g
Number of moles = 
= 0.135 mol.
To find the number of moles of LiClO₄:
Mass of LiClO₄ given = 4.78g
The molecular weight of LiClO₄ = 106.39g
Number of moles = 
= 0.0449 mol.

Answer:
Oxygen.
Explanation:
Oxygen is a chemical element that aides in the burning of materials and it is needed for humans to breathe.
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage through the breathing of oxygen used to obtain energy from the food ingested.
Hence, all cells in living organisms require oxygen and glucose to release energy.
