Lead is a bluish-white metal that will burn in air to produce lead (II) oxide. It is highly malleable and was used by the Romans to make pipes to carry water ("plumbing" is taken from the Latin name for lead "plum bum"). It has a relatively low melting point of 327°C and an atomic weight of 207.2 amu. Which property of lead is a chemical property?

Alan constructs a circuit that has two 1.5 V batteries arranged in series. These batteries power a single light bulb. What will happen if Alan adds another load in series?

The resistance of the circuit has increased, so more current will flow.

The voltage of the circuit has increased, so more current will flow.

The resistance of the circuit has decreased, so less current will flow.

The resistance of the circuit has increased, so less current will flow.

What is the danger of an uncontrolled chain reaction within the core of a nuclear fission reactor?

An uncontrolled chain reaction will use up all of the fuel in the reactor and force the fission of the metals that make up the core casing.

An uncontrolled chain reaction will produce enough heat to crack the reactor core open, releasing radioactive material.

An uncontrolled chain reaction will produce enough electrons to electrically charge the reactor core.

An uncontrolled chain reaction will produce enough heat to induce fusion in the reactor core, which will result in an explosion.

What question did the students pose before designing this experiment?

How does temperature affect the rate of the breakdown of hydrogen peroxide into water and oxygen?

How much dye do I need to use to determine the presence of hydrogen peroxide while performing this experiment?

How many plants should I put in the laboratory to have an abundance of oxygen in the air?

How does time affect the increase in temperature when hydrogen breaks down into oxygen and water?


SORRY, wrong answer crack the reactor core open, releasing radioactive material.


How does temperature affect the rate of the breakdown of hydrogen peroxide into water and oxygen?


40 points2
40 Points hydrogen peroxide into water and oxygen?

For new scientific knowledge to be gained, scientists must share their ideas. What is an appropriate way for scientists to communicate their findings?
