What is Li3N name

Li3N is lithium nitride

Which out of the two following molecules is trigonal planar shape NF3 or PCL3

Neither.

Due to the lone pairs on the N and P atoms, both molecules have a trigonal pyramidal shape.

When is the oxidation state of a metal indicated in the name of a compound

When the metal can exist in more than one oxidation state

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 is an example of food engineering

The development of irrigation.

What shape does the molecule ClF2 plus have

The ClF2+ ion is bent. (The VSEPR AXE notation is AX2E2 ). The ClF2- ion (AX2E3) is linear.

The products in a decomposition reaction

The products in a decomposition reaction depend on what the reactants are in that decomposition reaction. The products will be different depending on the reactants.

Food engineering focuses on

Food engineering focuses on inventing ways to make food more accessible to populations. This can be done, for example, by genetic modification.

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 reactive mo

Free radicals

When is the oxidation state of a metal indicated in the name of a compuond

The oxidation state of a metal is indicated in the name of a compound if and when that metal has more than one oxidation states. The oxidation state is then indicated by a Roman numeral placed in parenthesis next to the metal (Stock System).
