Answer:
cell - basic unit of structure and function of all living things
tissue - a group of cells that work together to perform a common function
organ - a group of tissues that work together to perform a common function
organ system - group of organs that work together to perform a common function
Explanation:
What you have there is the biological level of organization. It is how living things are organized from the simplest to the most complex. Each level makes up another level.
As you can see in your exercise, the basic unit of life is the cell and cells make up tissues, while tissues make up organs and so forth. There are higher levels of organizations passed organ system.
Cell - tissue - organ - organ system - organism - population - community - ecosystem - biosphere
Answer:
The pressure of N₂O₄ in the reaction vessel after the reaction is 290 mmHg
Explanation:
Nitrogen gas reacts with oxygen gas to form dinitrogen tetroxide.
N₂ (g) + 2O₂ (g) → N₂O₄ (g)
Therefore since by Avogadro's law equal volumes of all gases contain equal numbers of molecules, there fore as the gases are within the same vessel, thier partial pressure is equivalent to their concentration
from the reaction, 1 mole of N₂ react with 2 moles of O₂ to produce 1 mole of N₂O₄
Thus
1 mmHg of N₂ react with 2 mmHg of O₂ to produce 1 mmHg of N₂O₄
337 mmHg N₂ ×(1 mmHg of N₂O₄/ 1 mmHg of N₂) = 337 mmHg N₂O₄
580 mmHg O₂ ×(1 mmHg of N₂O₄/ 2 mmHg of O₂) = 290 mmHg N₂O₄
As seen from the above calculation, the limting reactant is oxygen and the partial pressure of N₂O₄ = 290 mmHg
