In the process of melting an ice cube, energy is (absorbed/released)
What is absorbed
The effect on atomic radius when moving from left to right on the periodic table
What is decreases
If two atoms have half-filled orbitals, the interactions balance at a small enough distance so the e–’s can be shared by both nuclei
What is a Covalent bond
dispersal of matter, disorder.
What is entropy
must be named using prefixes mono-, di-, tri-, tetra-, penta-, hexa-, hepta-, octa-, nona-, deca-.
What is covalent compound
atomic symbol surrounded by valence electrons.
What is Lewis structure
A chemical reaction that produces products with no external interference.
The value needed to convert from moles to grams of a substance
What is Molar mass
The pull felt on an electron from the nucleus
What is effective nuclear charge
Two bodies have reached a common temperature
What is thermal equilibrium
This type of reaction contains a fuel source and three chemicals: O2, CO2, and H2O.
What is combustion
A law stating that the elements, when listed in order of their atomic numbers, fall into recurring groups, so that elements with similar properties occur at regular intervals
What is Periodic Law
Many ions can be explained because they have gained or lost electrons and attain a
What is a full valence shell
States that regardless of the multiple stages or steps of a reaction, the total enthalpy change for the reaction is the sum of all changes.
