What are the reactants in a neutralization reaction? two elements an acid and a base an element and a compound a salt and water
Vitek1552 [10]

ok thank you for elaborating and you are correct in a neutralization reaction the reactants are the acid and base. the salt and water would be the product and the two elements could be anything meaning that it is most likely a mixture

Hope this helps

An element with the general electron configuration for its outermost electrons of ns2np1 would be in which element group?
Firdavs [7]

Electron configuration is the electron distribution in the molecular and atomic orbital. An element with configuration ns²np¹ will be in the 3A group. Thus, option B is correct.

<h3>What is electronic configuration?</h3>

The electronic configuration has been the arrangement and distribution of the sub-atomic particle, an electron in the atomic shells.

The electronic configuration given is, ns²np¹. Here, there are three valence electrons in the outermost orbit. As it has been known that the number of the valence electron gives the number of the group.

Therefore, option B. 3A group or 13 group is the correct option.

A student writes the following explanation of how certain molecules are formed.A process is used to chemically link smaller unit
tensa zangetsu [6.8K]

Answer:

polymerization

Explanation:

Student is explaining the process of formation of a polymer and the process is called polymerization.

Polymer is made up of joining repeating units. The repeating units are called monomers.  

Properties of the polymer is determined by the structure of monomer molecule.

For example, consider a well-known polymer Teflon.is made by the polymerization of tetrafluoroethane.  

Thus, the student is explaining polymerization.

Explain why hydrogen can only have 2 valence electrons around it when it bonds to other items. What is the maximum number of bon
lys-0071 [83]

Answer:

In first shell only 2 electrons are present in hydrogen only one electron is present in valence shell. To complete its duplet hydrogen can share lose or gain only one electron to form chemical bond.

Hydrogen can form only one bond.
