Representing Formula Flashcards
Define structural formula.
The position of all atoms in a molecule and how they are layed out.
Define General Formula..
How a molecule is usually written.
Define Displayed Formula.
The drawing of the compound.
Define Empirical Formula.
Simplest whole ratio number of atoms present in the compound.
Define Molecular formula.

State and explain 2 anomalous properties of ice caused by hydrogen bonding.
1.Water has a relatively high melting and boiling points it requires a lot of energy to overcome hydrogen bonds
- Ice is less dense than water, because it has an open lattice structure
Define dative covalent bond.
The strong electrostatic attraction between a shared pair of electrons and the nuclei of the bonded atoms, with the bonded pairs of electrons donated from the same atom i.e nitrogen.
Why is water more dense than ice?
Hydrogen Bonds hold H2O molecules in water.
