Write the shorthand electron configuration for the ion O2− (oxide ion).

How many orbitals are in the 3p sublevel?

For the reaction N2 + 3 H2 → 2 NH3, if 5.0 g N2 reacts with 2.0 g H2, which is the limiting reactant?

Four identical particles, each of mass 1.5 kg, are located at x = ±2.0 m and x = ±1.0 m on the x-axis. Their y-coordinates are all zero. The rotational inertia about the y-axis is:

To increase the rotational inertia of a solid disk about its central axis without changing its mass, you should:

An ice skater with rotational inertia I₀ spins with angular speed ω₀. She pulls in her arms and her angular speed becomes 3ω₀. Her new rotational inertia is:

A student is spinning on a frictionless turntable with arms extended. When the student pulls the arms inward:

An optimal tariff is defined as the tariff rate that:

Scale economies are said to be present when

Governments choose to use voluntary export restraints (VERs) rather than tariffs because
