Mixtures
The three types of mixtures
What are solutions, colloids and suspensions?
The qualities of a suspension
What are the presence of large solutes that separate readily when not moving?
The nature of a covalent bond
What is the bond formed when atoms share electrons?
The rational behind covalent and ionic bonds
What is the achievement of stability through the filling of the outer electron shells of the atoms involved?
The possible locations of hydrogen bonds
What are within molecules and between molecules?
The typical appearance of a solution
What is clear?
A major suspension in the body
What is blood?
The name of 2 substances associated with breathing in mammals that are formed by covalent bonds
What are Oxygen O2 and Carbon Dioxide CO2?
The term for an atom with positive electrical charge and an atom with a negative electrical charge.
What is a cation (meow) (+ve) and what is an anion (-ve)
The names of the 3 types of chemical reactions
What are synthesis, decomposition and exchange reactions?
The most important solvent in the body
What is water?
One way that a compound and a mixture differ
What is:
1. The components of a mixture are chemically unchanged whereas the components of a compound are chemically changed to create that compound.
2. The components of a compound can only be separated by breaking chemical bonds whereas the components of a mixture can be separated via processes such as filtration, straining, evaporation & centrifugation.
The name of the substance that is made of 2 hydrogen atoms and one oxygen atom
What is water or H2O?
The force that draws 2 atoms with opposite electrical charges together.
What is electrostatic attraction?
The term for constructive processes in the body
What is anabolic?
The typical appearance of a colloid
What is translucent or milky that often reflects light?
The number of types of chemical bonds that exist
What are 3?
The meaning of the term "polar molecule" when water is described.
What is the uneven sharing of electrons between hydrogen and oxygen creates a slightly positive charge on the hydrogen side and slightly negative charge on the oxygen side.
The name of the force that creates a hydrogen bond
What is an electrostatic attraction?
The term for decomposition reactions in the body
What is catabolic?
The name of the ability of a colloid to transform from a liquid to a solid and back again
What is sol-gel transformation?
The names of the types of chemical bonds
What are Covalent, Ionic and Hydrogen bonds?
The nature of an ionic bond
What is the transference of electrons from one atom to another?
The relative strength of a hydrogen bond compared to a covalent bond
What is weaker?
The term for reactions that require and input of energy and reactions that give off energy
What are endergonic and exergonic?
