100
show the presence of one substance by changing colors
What is an indicator
200
Pure substance that cannot be broken down into other substances Ex. Gold, Helium, Mercury, Lead, Silver etc.
What is an Element
200
Number of protons a particular element will contain ex. all carbon atoms *contain 6 protons*
What is an atomic number
200
When two or more substances interact and form one or more new substances
What is a Chemical Reaction

Substances with a pH above 7; release OH- ions in a solution
What is a base
200
contain both carbon and hydrogen ex. glucose
What is an organic molecule
300

Carbon(C) Oxygen (O) Nitrogen (N) Hydrogen (H)

Name 4 Major elements in living things

300
Similar forms of the same element that have different numbers of neutrons. Ex. carbon12, carbon13, carbon 14.
What is an Isotope
300
Starting Materials
What is a reactant
300
Describes how acidic or basic a substance is; scale is 0 to 14 Ex. stomach acid has a pH of 2, Human blood has a pH of 7.4 Ammonia has a pH of 11.5
What is a pH scale
300
Do not contain both carbon and hydrogen ex. water, oxygen

Name 4 minerals in humans

400

When atoms share or transfer electrons to create an attraction between them

What is Chemical Bond

400
Ending Materials
What is a Product
400
neutralization- mix of acidic solution with a basic solution to form a neutral solution
What is a neutral
400
organic molecules made up only of carbon and hydrogen atoms
What is hydrocarbons
500
*Substances containing two or more DIFFERENT elements chemically combined* Ex. Water (H20), Table Salt (NACL) Glucose (C6H12O6)
What are compounds
500

What is released when an unstable nucleus releases a particle (aka the nucleus of a Helium atom) transforming the atom into one with a mass 4 AU lower and 2 fewer protons 

What is alpha decay 

500
Water molecules cohere(stick) to one another as well as adhere to many other types of molecules. Ex. cohesion and adhesion help water to be transported from roots to leaves in plants. Water has the ability to resist temperature changes. Ex. oceans and large lakes help to moderate the temperature of nearby land. Density of ice is less than that of liquid water Water is an excellent solvent
What is The Importance Characteristics of Water
500
a compound that helps to maintain the pH of a solution
What is a buffer
500

removing water molecules to link monomers *build by removing water*

What is dehydration synthesis or condensation reactions
