Question 1: Which is NOT an example of how to charge an object?

• Transferring electrons
• Induction
• Polarization
• Refraction
• Friction

Answer:

D : Refraction involves the bending of light through different mediums and does not affect the charge of an object. Electrons can be transferred from one object to another, giving an object a negative charge, so Choice A is incorrect. Induction, Choice B, involves the redistribution of charge by bringing a charged object close to two stationary objects. If the charged object is negatively charged, the electrons of the stationary objects will be repelled away and one of the stationary objects will take on a positive charge while the other one will become negatively charged. Polarization, Choice C, occurs when electrons in an object are reconfigured temporarily. Friction, Choice E, is a common way that objects are charged. The example of rubbing the socked feet along the carpet demonstrates how friction causes the transfer of electrons, and thus charge, from one object to another

Question 2: The density of a substance is

• the relationship of its mass to a unit of volume
• the relationship of its volume to its chemical state
• the relationship of its weight to its volume
• the relationship of its inertia to its volume.

Answer:

• the relationship of its mass to a unit of volume

Question 3: In which part of the atom is 99 percent of its mass found?

• Orbitals
• Nucleus
• Protons
• Neutrons
• Electrons

Answer:

B : The nucleus contains the protons and neutrons of the atom. Together, they make up 99 percent of the atom's mass. Electrons, Choice E, are found in the orbitals, Choice A, surrounding the nucleus and do not have as much mass as the protons or neutrons. Protons and neutrons, Choices C and D, have similar masses, but neither makes up 99 percent of the atom's mass alone.Question 4: Which of the following is one main type of transfer that occurs in redox reactions?

• Transfer of carbon
• Transfer of hydrogen
• Transfer of nitrogen
• Transfer of sulfur
• Transfer of helium

Answer:

B : Redox reactions are chemical reactions that involve one species of the reactants being oxidized and another species of the reactants being reduced. The transferring of hydrogen between reactants is one type of redox reaction. Another type involves the transferring of oxygen between reactants, and the third type involves the transferring of electrons between the reactants. Carbon, nitrogen, sulfur, and helium, Choices A, C, D, and E do not drive redox reactions.

Question 5: Sulfur is mined chiefly for the production of...

• sulfa drugs
• sulfanilamide
• sulfuric acid
• superphosphates

Answer:

• sulfuric acid

Sulfuric acid is one of the most important acids used by industry.

Question 6: Ecology can best be described as the study of...

• different methods of fighting pollution
• the rate of land erosion
• changes in plants
• the relationship between the environment and living things

Answer:

• The relationship between the environment and living things

Question 7: Which one is most different from the other three?

• Pluto
• moon
• Neptune
• Uranus

Answer:

• moon

The moon is a satellite of a planet, Earth. The others are all planets. Pluto was the former moon of Neptune that had somehow escaped its orbit.

Question 8: The asteroid belt is

• Just beyond the orbit of Neptune
• between earth and mars
• between mars and Jupiter
• between Jupiter and Saturn

Answer:

• between mars and Jupiter

Question 9: In chemical reactions, water forms compounds that are classified as

• bases only
• acids only
• bases and acids
• baseless acids

Answer:

• bases and acids

Question 10: Humidity refers to ____

• the amount of moisture is in the air
• the distance to the nearest body of water
• the temperature of the air at a standstill
• the density of the air at the point of measurement

Answer:

• the amount of moisture is in the air
