from an external source of power

Explanation:

The energy needed for nuclear fusion comes from an external source of power.

Nuclear fusion is the combination of small sized atomic nuclei to form larger ones.

The reaction releases a huge amount of energy but also requires a large activation energy to start up.

  • The energy input require to drive two nuclei into fusion comes from an external source.
  • Nuclear fusion has a high activation energy which serves as the energy barrier for this reaction to take place.
  • The energy comes from the surrounding and once initiated, spontaneous chain reactions are set up.

In a sample containing a mixture of only these gases at exactly one atmosphere pressure, the partial pressures of carbon dioxide
Black_prince [1.1K]

Answer:

Explanation:

The pressure of a gaseous mixture is equal to the sum of the partial pressures of the individual gases:

ΣP_g_a_s = P_1+P_2+P_3+...+P_n

The prompt is trying to confuse you, but it actually tells us the pressure of the mixture to be 1 atm, but this can be converted to torr. Furthermore, we are informed only three gases are in the mixture: diatomic nitrogen, diatomic oxygen, and carbon dioxide:

P_g_a_s=1 \ atm = 760 \ torr= P_N_2+P_O_2+P_C_O_2\\760 \ torr = 582.008 \ torr + P_O_2 \ + 0.285 \ torr

Solve for Po2:

P_o_2=(760-582.008-0.285) \ torr = 177.707 \ torr

Thus, the partial pressure of diatomic oxygen is 177.707 torr.
