trigonal pyramidal

Why are prefixes not used in naming ionic compounds

two ions can combine in only one combination

How does the shape of a molecule affect the polarity of the molecule

C.A molecule that has a symmetrical shape will be a nonpolar molecule.

What effect does a lone electron pair have on molecular shape

The lone pair pushes bonding electron pairs away.

What is an example of food engineering

The development of irrigation.

What is a consequence of electron-pair repulsion around an atom

The atoms sharing the electron pairs will spread out around the central atom. Apex

How does a lone pair contribute to the molecular shape

The lone pair repels the electrons of the adjacent bonds more so than does a bonding pair of electrons, so thus alters the molecular geometry of the molecule.

What bond has a very strong dipole dipole force

a hydrogen bond

When food is exposed to air it can lose electrons this loss of electrons creates reactive molecules that work to destroy the chemical bonds in the food causing it to spoil what are these molecules cal

Free radicals
