Question 1

A student constructs a model of a neutral carbon atom (carbon-12) found in Michigan limestone deposits. Which statement accurately describes the location, composition, and electrical charges of the subatomic particles in this atom?

Protons (+1) and neutrons (0) are bound in the dense central nucleus, surrounded by electrons (-1) in outer energy levels. Protons (+1) and electrons (-1) form the central nucleus, while neutral neutrons orbit around the outside. Electrons (-1) and neutrons (0) are packed inside the nucleus, while positively charged protons orbit the outside. All subatomic particles carry positive charges and are evenly distributed throughout the entire volume of the atom.

Correct Answer:

Protons (+1) and neutrons (0) are bound in the dense central nucleus, surrounded by electrons (-1) in outer energy levels.

Question 2

During a science lab in Lansing, a student mixes solid baking soda (sodium bicarbonate) into liquid vinegar (acetic acid) inside a beaker. Rapid gas bubbling occurs and the temperature of the beaker drops significantly. Which observation provides the strongest evidence that a chemical reaction occurred?

The total mass of the liquid increased because vinegar expanded. A new gas substance was produced and a thermal energy change occurred. The baking soda dissolved completely to form a homogeneous mixture. The liquid changed color from clear to completely transparent.

Correct Answer:

A new gas substance was produced and a thermal energy change occurred.

Question 3

Engineers in Detroit manufacture durable synthetic nylon ropes using petroleum extracted from underground rock formations. Which description best explains nylon in this example?

Synthetic materials occur naturally in underground mineral deposits without requiring human intervention. Synthetic materials are created by physically chopping natural plant fibers into smaller fragments. Synthetic materials are manufactured by chemically processing natural resources to produce materials with specialized desired properties. Synthetic materials retain identical atomic arrangements to the original raw petroleum.

Correct Answer:

Synthetic materials are manufactured by chemically processing natural resources to produce materials with specialized desired properties.

Question 4

A hockey puck slides across smooth ice at the Van Andel Arena in Grand Rapids. After receiving an initial hit, the puck continues gliding across the ice at a constant speed in a straight line. Which law best explains this motion?

Gravitational pull pulling the puck sideways along the ice surface. Air resistance accelerating the puck in its direction of travel. Friction between the puck and ice pushing the puck forward. Inertia, which causes an object in motion to remain at constant velocity unless acted upon by an unbalanced net force.

Correct Answer:

Inertia, which causes an object in motion to remain at constant velocity unless acted upon by an unbalanced net force.

Question 5

A student generates transverse mechanical waves along a stretched spring during a physical science demonstration in Ann Arbor. If wave speed stays constant while frequency increases, what happens to wavelength?

The wavelength decreases because wave frequency and wavelength are inversely proportional. The wavelength increases because frequency and wavelength are directly proportional. The wavelength remains unchanged regardless of vibration frequency. The wavelength doubles immediately as frequency increases.

Correct Answer:

The wavelength decreases because wave frequency and wavelength are inversely proportional.
