Which of the following is an example of a pure element?
Show answer
Answer: C. Oxygen (O₂)
An element is a pure substance consisting only of atoms that all have the same number of protons in their atomic nuclei. Oxygen (O₂) is a diatomic molecule composed of only oxygen atoms, making it a pure element. Water, salt, and air are compounds or mixtures.
Which separation technique is most suitable for separating sand from water?
Show answer
Answer: C. Filtration
Filtration is used to separate insoluble solids from a liquid or gas using a filter medium that allows the fluid to pass through but not the solid. Sand is insoluble in water and can be separated by filtration.
What are the smallest particles of an element that retain the chemical properties of that element?
Show answer
Answer: C. Atoms
An atom is the basic unit of a chemical element. Atoms are the smallest particles of an element that still exhibit the properties of that element.
When a solute is dissolved in a solvent, the solute is the substance that:
Show answer
Answer: B. Is present in smaller amount
In a solution, the solute is the substance that is dissolved in another substance, the solvent. Typically, the solute is present in a lesser amount than the solvent.
Which of the following is a characteristic property of a nonmetal?
Show answer
Answer: D. Often brittle and dull in appearance
Nonmetals generally lack metallic properties. They are typically brittle, dull in appearance, and poor conductors of heat and electricity. Metals, on the other hand, are malleable, ductile, and good conductors.
