Fill the blanks.
During combustion, ______ reacts with fuel to produce ______ _______ and _____.
During combustion, OXYGEN reacts with fuel to produce CARBON DIOXIDE and WATER.
What are the 3 mechanisms of heat flow?
Combustion, Conduction, and Radiation.
What is a P orbital shaped like?
Barbell or dumbbell.
Define electronegativity?
The tendency for an atom of a given chemical element to attract shared electrons when forming a chemical bond.
What is the chemical formula for Decaphosphorus Dioxide?
Why is Energy hard to define?
It takes many different forms and can do many different things.
What is an insulator?
The transfer of heat through electromagnetic radiation.
How many P orbitals are there?
3
When does a double covalent bond form?
When atoms share two pairs of electrons.
What is the BIC name for Cd3 (PO4)2?
Cadmium (II) Phosphate
During Chemical Reactions, how does the amount of Chemical Potential Energy in substances compare as they change into different substances?
The energy amount begins to change along with whatever substance they transform into.
Would a substance that has good Electrical Conductivity also have good Thermal Conductivity? Why?
Yes because electricity can make heat which would just help conduct heat faster.
In what order do electrons fill orbitals from?
From the lowest energy state to highest energy state.
What atoms form a single covalent bond?
Hydrogen and flourine.
When do you omit then prefix "mono"?
When just one atom of the first element is in the formula.
How is the size of an anion different from a neutral atom?
These anions lose their particles or their charges making them smaller than their neutral atoms.
Why is Thermal Conduction in Metals a special case of Conduction?
The heat is carried by movements of the electrons as well as by movements of the atoms.
