Chemistry exam 1 Exam Study Guide Solutions ionic compound properties - ANSWER-- have a high melting and boiling point - they're solid at room temperature - are hard, but brittle, so they're not malleable or ductile - don't conduct electricity in solid state - are good conductors of electricity in liquid state or when dissolved in water - they vary from very soluble to insoluble in water, they're not soluble in non-polar solvents (oil) define ionic compounds - ANSWER-made by...

A father's age is twice the sum of the ages of his four sons. In 30 years, the total of the sons' ages will be twice the age of their father. How old is the father now? a) 24 b) 48 c) 32 d) 40 e) 36 - ANS d) 40 If the sum of the four son's ages is x at present, the father's age is 2x. In 30 years, the total of the son's ages will be x+4×30=x+120, whereas the father's age will be 2x+30. Therefore, x+120=2(2x+30), which yields x=20, and hence, the father's age at present i...

Chemistry definition correct answers Study of structure, properties, transformations of matter Matter correct answers Anything that has mass + takes up space Phases: solid, liquid, gas Condensed phases = solids + liquids Intermolecular Forces (IMF) correct answers = Interactions between molecules/atoms/ions Solution correct answers = Homogenous mixtures of 2+ pure substances In a solution, the solute is dispersed uniformly throughout the solvent - Solute = compound(s) in lesser amount - ...

1. particles are arranged in a random fashion ANS Amorphous solids 2. physical properties of solvents that are dependent on the concentration of the solute present and the identity of the solvent but not on the identity of the solute. They include vapor pressure, freezing point and boiling point ANS Colliga- tive properties 3. heterogeneous mixtures which appear to homogeneous one-phase mix- tures but are actually composed of particles too small to be seen with the naked eye ANS Colloids 4...
