Alex17521 [72]

The Number of moles required for MTBE is 2 as per molarity based chemistry theories.

  1. A flammable liquid with a distinct, unpleasant smell is called methyl tert-butyl ether (MTBE).
  2. Since the 1980s, it has been added to unleaded gasoline as a fuel additive to promote more effective burning.
  3. It is created by mixing chemicals like isobutylene and methanol. Gallstones can be removed with MTBE as well.
  4. In this type of treatment, surgically inserted special tubes are used to deliver MTBE directly to the gall bladders of the patients.
  5. Methyl tert-butyl ether is a colorless liquid with a distinct anesthetic-like smell. Vapors are narcotic and heavier than air. 131 °F boiling point. 18 °F is the flash point.
  6. It is miscible in water and less dense than water. Boosts the octane of gasoline.
  7. Therefore it has 2 moles of oxygen.

Consider this mechanism:
DerKrebs [107]

Answer:

ClO^- + I^-\rightarrow IO^- + Cl^-

Explanation:

Given a reaction mechanism, we will typically have catalysts and intermediates which will not be observed in the final balanced overall reaction. In order to obtain a net reaction, we need to add all the separate steps of the given reaction.

First of all, the reactants are combined followed by a combination of products. The repeating species on both sides of the final equation are then canceled out. Let's sum everything we have in our steps:

ClO^- + H_2O + I^- + HClO + OH^- + HIO\rightarrow HClO + OH^- + HIO + Cl^- + H_2O + IO^-

Repeating species that can be canceled out are:

H_2O,~HClO,~OH^-,~HIO

This leaves a net reaction of:

ClO^- + I^-\rightarrow IO^- + Cl^-

Andru [333]

Answer:

The answer to your question is letter B. 2

Explanation:

Unbalanced reaction

                  NH₃   +   O₂   ⇒     HNO₃   +   H₂O

            Reactants      Elements     Products

                   1                     N                  1

                   3                    H                  3

                   2                    O                 4

Balanced reaction

                   NH₃   +   2O₂   ⇒     HNO₃   +   H₂O

           Reactants      Elements     Products

                   1                     N                  1

                   3                    H                  3

                   4                    O                 4            

When the reaction is completely balanced the coefficient of O₂ is 2
