Energy

Back 24

The capacity to do work or supply heat
Energy transformations cannot occur w/o any loss
Heat flows from hotter object to colder object

Front 25

Petroleum

Back 25

we already know how to use it
it has a high energy content
It is easy to store and transport
It emits CO2 when used to generate energy. Many are hydrocarbons, alkanes,

Front 26

Front 27

electronegativity

Back 27

Values increase from left to right in a row of the periodic table, and decrease going down a group.
Fluorine and Oxygen have the highest values
Lithium and sodium have low values
it is a measure of hte attraction of an atom for an electron in a chemical bond

Front 28

Polarity

Back 28

The larger the difference in electromagnetism, the more polar the bond

for it to be polar it must be a nonmetal

linear cannot be polar

Front 29

Potable water

Back 29

water that is safe to drink and cook with

Front 30

Aqueous solution

Back 30

An aqueous solution is a homogeneous mixture of uniform composition.


Solutes are substances that dissolve in water to make an aqueous solution.

Some covalent compounds and

some ionic compounds can dissolve to form an aqueous solution

All aqueous solutions contain water.

Front 31

Solutions

Back 31

A solution is a homogeneous mixture of uniform composition

Solutes are substances that dissolve in a solvent

A solvent is a substance that is capable of dissolving other substances

Front 34

Catalyst

Back 34

Only in exothermic reaction
Catalysts provide alternative reaction pathway that proceed with less energy input
Catalyst are not tranformed due to the reaction
Catalysts are used to refor petrolum

Front 35

Back 35

breaks down large hydrocarbons molecules into smaller ones by heating them

Front 36

Catalyst cracking

Back 36

catalyst is used to maek hydro carbon molecules smaller with low temps
