Amolecule of a covalent compound contains three atoms of fluorine (f) and one atom of boron (b).
what is the correct molecular formula and chemical name of the compound described in this statement?
f3b; trifluorine boronide
bf; boron fluoride
bf3; boron trifluoride
f3b; boron trifluorine

BF₃; boron trifluoride

Explanation:

The molecular formula of the compound would be BF₃

The atoms making up the compound consists of B and F.

In covalent bonds, electrons are shared between atoms for the bonds to form. Boron has 3 valence electrons and would freely share with other atoms for it to have a stable configuration. Fluorine requires just one electron to have a stable configuration. Three fluorine atoms would make the bonding work.

This leaves us with a BF₃ compound

Chemical name is Boron trifluoride(3 atoms of fluorine)

b is the correct answer

mark me brainliest and hope this

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
