Answer: Option (c) is the correct answer.

Explanation:

A reaction which is able to occur in fraction of seconds or which is able to occur at an instant rate of time means that reaction is at a very fast rate.

Rusting of iron is not an immediate process as it occurs due to the humidity present within the air an oxide layer develops on the surface of iron. This layer formation does not occur in an instant.

Photosynthesis is a process of formation of food by the plants for themselves in the presence of air, sunlight, carbon dioxide and water.

Rotting wood also takes time and may occur over a period of month or more.

An explosion is an instantaneous process as it occurs within a fraction of seconds.

Thus, we can conclude that out of the given options an explosion is an example of a chemical reaction that occurs at a very fast rate.

<h3>How are elements named?</h3>

Elements have been given names based on a variety of factors, including their characteristics, the compound or ore from which they were extracted, the method by which they were found or acquired, mythical characters, locations, and well-known individuals. Some components have names that are descriptive and are based on one of their attributes.

The International Union of Pure and Applied Chemistry chooses the official element names and symbols (IUPAC). However, different nations frequently use similar names and symbols for elements. Official names and symbols for elements are not given until after their discovery has been confirmed. The discoverer may then suggest a name and a symbol.

There are name standards for several element groupings. Names of halogens end in -ine. All noble gas names, save helium, end in -on. The names of most other elements finish with -ium.

Show your calculation by uploading a picture. Calculate the molar mass of ammonia, NH3

Cloud [144]

Answer:

17.04 g/mol

Explanation:

Molar Mass of NH₃

we know that

Nitrogen has 14.01 gram/mol

And Hydrogen has 1.01 gram/mol

but we have 3 Hydrogens So we multiply

1.01 by 3 i.e., 3.03

Now, add

14.01

+ 3.03

17.04

So, The molar mass of ammonia, NH₃ is

17.04 g/mol
