If the volume of a container of air is reduced by one-half what happens to the partial pressure of oxygen within the container?
katovenus [111]

Decreasing Pressure. The combined gas law states that the pressure of a gas is inversely related to the volume and directly related to the temperature. If temperature is held constant, the equation is reduced to Boyle's law. <em>Therefore, if you decrease the pressure of a fixed amount of gas, its volume will increase.</em>

The table shows a chemical equation and the dimensional analysis used by a student to calculate the number of moles of Ba3N2 req
a_sh-v [17]

Answer:

c 3 mol of Ba(OH)₂ and 1 mol of Ba₃N₂ should be interchanged  

Explanation:

              Ba₃N₂ + 6H₂O → 3Ba(OH)₂ + 2NH₃

n/mol:                                      9.2

\text{Moles of Ba$_{3}$N}_{2} = \text{9.2 mol Ba(OH)}_{2} \times \dfrac{\text{1 mol Ba$_{3}$N}_{2}} {\text{3 mol Ba(OH)}_{2}}= \text{x mol Ba$_{3}$N}_{2}

They want to find moles of Ba₃N₂, so that should be in the numerator of the conversion factor,

Moles of Ba(OH)₂ should be in the denominator to cancel the units in 9.2 mol Ba(OH)₂,
