What is they are homogeneous?
This solution surrounds a cell that has a higher concentration of salt solution inside.
What is hypotonic?
This solution surrounds a cell that has a lower concentration of salt solution inside.
What is hypertonic?
The movement of water across a membrane.
What is osmosis?
The process by which substances move from areas of higher concentration to areas of lower concentration.
What is diffusion?
This is why solutions containing acids conduct an electric current.
What is acids break apart to form ions in water?
A strong acid.

Balancing Game Category Tell whether the reaction is balanced or unbalanced.
A reaction in which a compound is broken apart into simpler substances can be classified as this type of reaction.
What is decomposition?
When heat is being released, this type of chemical reaction is taking place.
What is exothermic?
The substance that slows down or stops a chemical reaction.
What is an inhibitor?
When two simple substances chemically react to form a more complex substance, this type of reaction has taken place.
What is synthesis?
This happens to the reaction rate when particles are able to collide more often and with more energy.
What is increases?
Fe + 2HCl → FeCl2 + H2
What is balanced?
H2O → H2 + O2
