The chemical compound lithium fluoride contains a(n) chemical bond because electrons are

Answer : The chemical compound lithium fluoride contains an ionic chemical bond because electrons are transferred.

Explanation :

Covalent compound : It is defined as the compound which is formed by the sharing of electrons between the atoms forming a compound.

The covalent compound are usually formed when two non-metals react.

Ionic compound : It is defined as the compound which is formed when electron gets transferred from one atom to another atom.

Ionic compound are usually formed when a metal reacts with a non-metal.

In lithium fluoride, lithium is an alkali metal and has one valence electron and fluoride is a non-metal and has 7 valence electrons.

When lithium atom donates an electron to a fluoride atom then it forms an ionic compound that is lithium fluoride (LiF).

Hence, the chemical compound lithium fluoride contains an ionic chemical bond because electrons are transferred.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
