Explanation:

Hello!

Let's solve this!

A hemiacetal is the product of a reaction between an aldehyde and an alcohol.

The structure is

      R

       |

RO-C-H

       |

      OH

An acetal has two alkoxy groups. The structure is :

        H

         |

 OH-C-OR '

         |

        OR ''

Of the compounds given, the first two are hemiacetals.

The next three are acetals and the last two are others.

pashok25 [27]

Answer: Combustion reactions are characterized by the reaction of a substance with O2 to form one or more oxygen, often water. Combustion reactions emit heat, and they are important because most of society's energy is derived from them. Ex.: CH4 (g) + 2O2 (g) -- CO2 (g) + 2H2O (g)

Sulfuric acid was once produced through the reaction of sulfur trioxide with water. Sulfur trioxide can form through the reactio
vekshin1

Answer 1) In the given reaction of sulfuric acid


2NO_{(g)} + O_{2}_{(g)} ---->  2NO_{2}_{(g)}


2NO_{2}_{(g)} + 2SO_{2}_{(g)} ---->  2NO}_{(g)} + 2SO_{3}_{(g)}


On addition of nitrogen monoxide gas the reaction rate increases and more amount of product is formed.


So, it is clear that NO is the catalyst in this reaction.


Answer 2) This can be proven that NO is catalyst because it increases the rate of the reaction, but it is not consumed during the reaction, and it also gets regenerated at the end of reaction.


Hence, nitrogen mono oxide is considered as the catalyst in the given reaction.


Answer 3) It increases the rate of reaction by decreasing the activation energy of the reaction. Also it can be clearly seen in this reaction the NO is reacting with oxygen to lower the energy of activation. So, it is providing an alternative pathway for proceeding the reaction. This all confirms the assumptions of NO being the catalyst.


2NO_{(g)} + O_{2}_{(g)} ---->  2NO_{2}_{(g)}
