Answer:
Partial pressure
Explanation:
Since she's measuring the pressure exerted by each gas, it's partial pressure. If she were measuring the collective pressure, it would be total pressure.

Explanation:
Answer:Animal cells are eukaryotic cells that have both a membrane-bound nucleus and other membrane-bound organelles.
Explanation:Animal cells are eukaryotic cells that have both a membrane-bound nucleus and other membrane-bound organelles. These organelles carry out specific functions that are needed for the normal functioning of the cell. Plant and animal cells are similar in that they are both eukaryotic and have similar types of organelles
Answer:
Ammonia (NH3)
Explanation:
its an ionic compound where N nitrogen is bonded to covalent molecules
Answer is: -963,8 kJ.
Q₁ = m(Fe) · C · ΔT₁.
C - specific heat capacity of liquid iron, C(Fe) = 0,82 J/g°<span>C.
</span>m(Fe) = 575 g.
ΔT₁ = 1181 - 1825 = -644°C.
Q₁ = -859306,5 J = -859,3 kJ.
Q₂ = m(Fe) · C · ΔT₂.
ΔT₂ = 293 - 1181 = -888°C.
C - specific heat capacity, C(Fe) = 0,44 J/g°C.
Q₂ = -224664 J = -224,66 kJ.
Q₃ =- heat of fusion, ΔH = 209 J/g.
Q₃ = 120175 J = 120,17 kJ.
Q = Q₁ + Q₂ + Q₃ = -963,8 kJ.
