Test 1 Flashcards
changed during a chemical reaction
Reactants
Exothermic
release more energy than they absorb.
Endothermic
absorb more energy than they release.
Changes in ph and temperature
Disruptions in homeostasis can prevent enzymes from properly functioning.
activation energy
amount of energy
needed to start a chemical
reaction.
Chemical reaction/ reaction rate
Speeds up
made by a chemical reaction.
Products
Equilibrium
reactants and
products form at the same
rate.
catalyst lowers?

Electrons are part of atoms that involved in all types of
Bonding
Covalent bonds occur
when atoms
Share electron 
Ionic bonds occur when
Atoms gain or lose electrons
Water
Polar (Slightly charged regions) covalent molecule 
Hydrogen bonds
Slightly positive Hydrogen atoms and slightly negative oxygen atoms
Are in the nucleus and have a positive charge
Protons
Are also in the nucleus and have no charge
Neutrons
Orbit the nucleus and have a negative charge
Electron
Hydrogen bonds are responsible for four important properties of water
• Universal solvent (adhesion)
• High specific heat
• Surface tension (cohesion)
• less dense as a solid 
 Bond energy
The amount of energy that it takes to break a bond between two atoms
