Question 1

What does Charles’ Law state?

Answer 1

At constant pressure, the volume of a given mass of gas varies directly with absolute temperature.

Question 2

What does Boyles’ Law state?

Answer 2

The volume of a gas is inversely proportional to the absolute pressure at constant temperature.

Question 3

What does Dalton’s law state?

Answer 3

The total pressure of a gas = sum of the pressures exerted by the individual gas components. The partial pressure is the pressure that would be obtained if the gas were alone in the same total volume at the same temperature.

Question 4

What does Kopp’s law state?

Answer 4

Kopp’s law states that at room temperature, the sum of heat capacities of the individual elements of a solid is approximately equal to the total heat capacity of the solid.

Question 5

What laws are apart of the ideal gas law?

Answer 5

1. Charles’ Law
2. Boyle’s Law
3. Dalton’s Law

Question 6

When does a gas behave ideally?

Answer 6

Low pressures and high temperature (higher than critical temperature).

Question 7

Explain the pattern of the atomic radii across the periodic table.

Answer 7

The atomic radius decreases as we move from left to right in a period and it increases when we go down a group.

Question 8

Explain the pattern of electronegativity across the periodic table.

Answer 8

Electronegativity decreases down a group and the highest electronegativities are found at the right end of the periods.

Question 9

Explain the relationship between atomic radii and stability.

Answer 9

Elements with smaller radii are more stable than those with larger radii.

Question 10

What is electronegativity?

Answer 10

The ability of an atom to attract an electron.

Question 11

List examples of metalloids

Answer 11

Boron (B), Silicon (Si), Germanium (Ge), Arsenic (As), Antimony (Sb), Tellurium (Te), and (sometimes) polonium (Po).
