What is the periodic table, and what is its significance in the study of chemistry?
NeX [460]

Explanation:

<u>Periodic table is the tabular display of elements that are arranged by the increasing atomic number. </u>

Structure of the periodic table shows various periodic trends.

<u>Significance: </u>

The periodic table is very important because it gives an organized way to provide lots of information about the elements and how they can be related to one another. The table gives a systematic approach to study the elements and their properties. The table can also be used to predict the properties of the elements which have not been discovered yet.

NH3 + HCI —&gt; NH4CI synthesis O decomposition O single replacement O double replacement​
wlad13 [49]

Answer:

synthesis

Explanation:

The reaction given is a synthesis reaction or combination reaction.

Given equation:

                        NH₃  +  HCl   →   NH₄Cl

In a synthesis reaction, a single product is formed from two or more reactants

                          A + B →  C

The formation of compounds from the union of constituent elements also falls into this category.

So the given reaction is a synthesis reaction.

In a decomposition reaction two or more products are formed from a single reactant

In a single replacement reaction, one substance replaces another.

In double replacement reactions partners in a chemical specie are exchanged.

Therefore the given reaction is a synthesis reaction

Calculate the ph of a mixture that contains 0.18 m of hno3 and 0.24 m of hbro
Kobotan [32]
HNO3 is a strong acid while HBrO is weak acid.
Therefore we ignore the presence of the weak acid such that we consider the pH of the strong acid.
Therefore; since pH= - log (H+)
Hence pH= -log 0.18
                = 0.745
Thus the pH of the mixture is 0.745
