Solution Steps

Step 1: Analyze Reaction (1) - Ionization of Cobalt

The reaction given is: \[ \mathrm{Co}(g) \rightarrow \mathrm{Co}^{+}(g) + e^{-} \] This is the ionization of cobalt, where an electron is removed from a neutral cobalt atom to form a positively charged ion. The energy required for this process is the ionization energy.

Step 2: Determine if Reaction (1) Absorbs or Releases Energy

The ionization energy for cobalt is given as \(760.4 \, \mathrm{kJ/mol}\). Ionization energy is the energy required to remove an electron, so this process absorbs energy.

Step 3: Check if Energy Calculation for Reaction (1) is Possible

Since the ionization energy is provided, it is possible to calculate the energy absorbed by the reaction. The amount of energy absorbed is equal to the ionization energy.

Step 4: Analyze Reaction (2) - Electron Affinity of Cobalt

The reaction given is: \[ \mathrm{Co}(g) + e^{-} \rightarrow \mathrm{Co}^{-}(g) \] This is the electron affinity process, where an electron is added to a neutral cobalt atom to form a negatively charged ion.

Step 5: Determine if Reaction (2) Absorbs or Releases Energy

The electron affinity for cobalt is given as \(63.7 \, \mathrm{kJ/mol}\). Electron affinity is the energy released when an electron is added to an atom, so this process releases energy.

Step 6: Check if Energy Calculation for Reaction (2) is Possible

Since the electron affinity is provided, it is possible to calculate the energy released by the reaction. The amount of energy released is equal to the electron affinity.

Final Answer

  • Reaction (1) absorbs energy: \(\boxed{\text{absorb}}\)
  • Possible to calculate energy for Reaction (1): \(\boxed{\text{yes}}\)
  • Energy absorbed by Reaction (1): \(\boxed{760.4 \, \mathrm{kJ/mol}}\)
  • Reaction (2) releases energy: \(\boxed{\text{release}}\)
  • Possible to calculate energy for Reaction (2): \(\boxed{\text{yes}}\)
  • Energy released by Reaction (2): \(\boxed{63.7 \, \mathrm{kJ/mol}}\)

A glider of mass 0.240 kg is on a frictionless, horizontal track, attached to a horizontal spring of force constant 6.00 N / m. Initially the spring (whose other end is fixed) is stretched by 0.100 m and the attached glider is moving at 0.400 m / s in the direction that causes the spring to stretch farther. What is the total mechanical energy (kinetic energy plus elastic potential energy) of the system? Express your answer with the appropriate units. When the glider comes momentarily to rest by distance is the spring stretched? Express your answer with the appropriate units. x= Value Units Units input for part B
