Answer:

Hydrogen

Explanation:

Just to provide some background, an element is a pure substance consisting of only one type of atom. An atom is the smallest constituent of matter. All elements are comprised of a single type of atom (e.g., gold is composed of gold atoms, helium of helium atoms, phosphorus phosphorus, and so on).

A molecule is a group of two or more atoms. They can be the same atom (homonuclear), such as or different atoms (heteronuclear).

Some examples of homonuclear molecules include:

Hydrogen (H2)

Nitrogen (N2)

Phosphorus (P4)

Some examples of heteronuclear molecules include:

Carbon dioxide (CO2)

Sulfuric acid (H2SO4)

Methane (CH4)

What is the Lewis dot structure for the formula ch3br?

Alenkasestr [34]

You may find the Lewis dot structure of the CH₃-Br in the attached picture.

Explanation:

In the Lewis dot structure we represent the unpaired electrons using dots.

Bromide have one electron shared with one electron from the carbon to form a covalent bond, while the remaining electrons remains unpaired. We represent the six unpaired electrons of the bromide with dots.

Write the reaction of crystal violet with 1 equivalent of HCl.

tankabanditka [31]

The reaction of crystal violet with 1 equivalent of HCl will be when leuco crystal reacts with HCl to crystal violet it forms hexamethyl pararosaniline chloride.

<h3>What are crystal violet?</h3>

These are the trinary methane compounds mainly used for staining and dying of anything like bacteria or fungi and other name for it is methyl violet 10 B.

In reaction the HCl gets protonated and lone pair of nitrogen atom gives them positive charge.

3C6H6(3NH)3 + HCl will give 3C6H6(3NH)3NH4Cl + 2H

Therefore, reaction of crystal violet with 1 equivalent of HCl will be when leuco crystal reacts with HCl to crystal violet it forms hexamethyl pararosaniline chloride.
