Acids and salt assessment

1. Definitions and properties

a. Highlight which of the following is a basic oxide.

•Lithium oxide
•Aluminium oxide
•nitrogen dioxide

b. Define what is meant by a strong acid.

c. For the weak alkali ethyl amine, predict its likely pH (at 1 mol/dm), and the
colour it will turn universal indicator.

d. Explain two ways strong acids can be differentiated from weak acids without
the use of universal indicator.

Write a net ionic equation to show that hydrofluoric acid, behaves as an acid in water.

Match the following vocabulary terms to their definitions. 1. amount of energy required to change 1 gram of material from the solid to the liquid state at its melting point 2. a measure of the kinetic energy of the particles of a substance 3. the amount of heat energy required to raise the temperature of 1 gram of liquid water from 14.5°c to 15.5°c 4. amount of energy required to change 1 gram of material from the liquid to the gaseous state at its boiling point 5. the amount of energy required to change 1 gram of a substance 1°c a. temperature b. latent heat of vaporization c. latent heat of fusion d. calorie e. specific heat

Rocks, as they are compressed, begin forming mountains above the earth's surface when two continental plates converge. the continental crust increases in depth as the mountains grow above. the himalayan mountains formed at a convergent plate boundary in this manner. the rocks are smashed together causing them to due to the intense heat and pressure from the colliding plates and eventually forming rock. a) melt; igneous b) layer; sedimentary c) recrystallize; metamorphic d) melt into the earth's interior; metamorphic
