What distinguishes ionic compounds from molecular compounds?
What distinguishes ionic compounds from molecular compounds?
- Ionic compounds are formed only from nonmetals while molecular compounds can contain metals.
- Ionic compounds consist of charged particles while molecular compounds consist of neutral molecules. (correct)
- Ionic compounds have lower melting points than molecular compounds.
- Ionic compounds do not conduct electricity, while molecular compounds do.
Which of the following correctly describes the pH scale?
Which of the following correctly describes the pH scale?
- A pH of 7 indicates a weak acid.
- The pH scale ranges from 0 to 14, with lower numbers indicating basic substances.
- The pH scale indicates the concentration of hydroxide ions in a solution.
- The pH scale is logarithmic and reflects the concentration of hydrogen ions. (correct)
What is the correct process for naming an acid?
What is the correct process for naming an acid?
- For oxyacids, if the anion ends in 'ate', the acid name ends with 'ic'. (correct)
- Use the name of the anion and add 'acid' for all acids.
- Acids are named by the number of hydrogen ions they contain.
- For monoatomic anions, drop the suffix and add 'ate' followed by 'acid'.

Flashcards
What is distance?
What is distance?
Distance is the total length of the path an object travels. It is a scalar quantity, meaning it only has magnitude, not direction.
What is displacement?
What is displacement?
Displacement is the overall change in position of an object from its starting point to its end point. It is a vector quantity, meaning it has both magnitude and direction.
What is speed?
What is speed?
Speed is the rate at which an object moves, calculated by dividing the distance traveled by the time taken. It is a scalar quantity, meaning it only has magnitude.
What is velocity?
What is velocity?
