Answer:

A chemical reaction involves, breaking and making of bonds between reactants to give rise to formation of new products. A chemical reaction is basically rearrangement of atoms.

By definition, chemical reactions are those that cause the chemical bonds between atoms to break and reorganize, giving rise to different substances.

<h3>Substances present in a chemical reaction</h3>

In a chemical reaction there are the substances that react, that is, the reactants, and the substances produced, called products.

<h3>Mass of a chemical reaction</h3>

The mass of the participating substances is the same before and after the reaction, that is, it is conserved. This happens because only a rearrangement takes place between the atoms of the reactants, which break and form new bonds.

<h3>Energy necessary of a chemical reaction</h3>

It must be taken into account that for a chemical reaction to occur the reactants must collide since energy is necessary to break the chemical bonds between atoms.

<h3>Summary</h3>

In summary, chemical reaction is the way one substance reacts against another. In this way, the chemical bonds between atoms are broken and new bonds are formed.

goldfiish [28.3K]

Answer:

The structures are shown in the figure.

Explanation:

The primary hydrogens are those which are attached to primary carbon.

Primary carbons are the carbons which are attached to only one carbon.

Primary carbons is bonded to three hydrogens.

In order to draw such structure we will draw structures which will have carbon with three hydrogens or no hydrogens (quaternary)

The structures are shown in the figure with clear marking.

Calculate the ph of this solution. round to the nearest hundredth. poh = 3.45 ph =
maks197457 [2]

The potential of hydrogen pH of the solution with the given value of pOH to the nearest hundredth is 10.55.

What is pH of solution?

The pH of a solution is defined as the logarithm of the reciprocal of the hydrogen ion concentration  [H+] of the given solution.

It is expressed as;

pH = -log[ H⁺ ]

Also,

pH + pOH = 14

Given that;

  • pOH = 3.45
  • pH = ?

We simply substitute our values into the expression above.

pH + pOH = 14

pH + 3.45 = 14

pH = 14 - 3.45

pH = 10.55

Therefore, the potential of hydrogen pH of the solution with the given value of pOH to the nearest hundredth is 10.55.
