Question 1
A student observes that lithium (Li) and sodium (Na) react vigorously with water, releasing hydrogen gas and forming basic solutions. Which property explains why these elements display similar chemical reactivity?
Correct Answer:
They have the same number of valence electrons.
Question 2
During a lab investigation, a student combines hydrochloric acid (HCl) and sodium hydroxide (NaOH) in a closed, insulated calorimeter. The temperature of the liquid increases. Which statement correctly characterizes this reaction?
Correct Answer:
It is an exothermic reaction because chemical energy is transformed into thermal energy released to the surroundings.
Question 3
A toy car is pushed across a flat wooden table with a constant horizontal force. If the pushing force is exactly equal in magnitude to the frictional force acting on the car, what will happen to the car's motion?
Correct Answer:
The car will move at a constant velocity.
Question 4
A hydro-electric dam converts the gravitational potential energy of stored reservoir water into electrical energy. Which energy transformation sequence best describes this process?
Correct Answer:
Gravitational potential energy -> kinetic energy of moving water -> mechanical energy of turbine -> electrical energy
Question 5
Which portion of the electromagnetic spectrum has shorter wavelengths and higher frequencies than visible light, causing it to damage biological molecules such as DNA upon prolonged skin exposure?
Correct Answer:
Ultraviolet radiation
