Select the type of energy involved in each step. You turn on the burner of a gas stove. a) chemical b) thermal c) mechanical d) electrical The gas ignites. a) chemical b) thermal c) mechanical d) electrical The gas warms the water in the pan.

If this energy were used to vaporize water at 100.0 ∘C, how much water (in liters) could be vaporized? (Assume the density of water is 1.00 g/mL.)

A sample of Cl 2 Cl2 gas has a volume of 25.0 L 25.0 L at a pressure of 1.50 atm and a temperature of 23 ∘ C. 23 ∘C. What volume, in liters, will the gas occupy at 3.50 atm and 261 ∘ C? 261 ∘C? Assume ideal behavior.

Suppose an empty plastic bottle is sealed tightly at room temperature and then placed in the freezer. After some time the bottle changes shape. The bottle becomes slightly crushed as the volume of the air in it decreases.

Consider the following two-step reaction mechanism: A (g) + B (g) → X (g) + Y (g), X (g) + C (g) → Y (g) + Z (g). Which of the following statements about this mechanism is or are true? A. Both of the steps in this mechanism are bimolecular. B.

A covalent chemical bond is one in which outer-shell electrons of two atoms are shared so as to satisfactorily fill the outer electron shells of both atoms. protons and neutrons are shared by two atoms so as to satisfy the requirements of both atoms.

To break a chemical bond, energy must be (1) absorbed (2) destroyed (3) produced (4) released

In an experiment, 132 grams of potassium bromide (KNO3) was dissolved in 100 grams of water at 70 °C in 1 minute.
