1 answer:

7 0

Two eukaryotic animal cell organelles that have roles similar to the organs of the human digestive system are lysosome and mitochondria. The lysosome is like our stomach, it is responsible for digesting or breaking down the food consumed by the cell. Mitochondria is like the small intestine, it is responsible for converting the food we eat into nutrients and minerals needed for the cell.

What volume of o2 at 874 mmhg and 33 ∘c is required to synthesize 18.0 mol of no?

Nataly [62]

1) Write the balanced chemical equation

4NH3 + 5O2 ----> 4NO + 6H2O

2) Write the molar ratios

4 mol NH3 : 5 mol O2 : 4 mol NO : 6 mol H2O

3) Write the proportions with the desired quantity of NO and the unknown quantity of O2

5 mol O2 / 4 mol NO = x / 18.0 mol NO

Solve for x: x = 18.0 mol NO * 5 mol O2 / 4 mol NO = 22.5 mol O2

4) Use the ideal gas equation to convert moles to volume

pV = nRT => V = nRT / p

n = 22.5 mol

R = 0.082 atm*liter / K * mol

T = 33 + 273.15 = 306.15 K

p = 874/760 atm = 1.15 atm

V = 22.5 mol * 0.082 atm*liter/K*mol * 306.15 K / 1.15 atm = 491.17 liter

Answer: 491 liters of O2

Atmospheric pressure at the summit of mount everest is about one third the pressure at sea level, which is 760 mm hg. if oxygen

vichka [17]

Atmospheric pressure at sea level is 760 mmHg.
We have been told that at the summit the pressure is only one third the pressure at sea level.
Then the pressure at the mountain top is $\frac{760}{3}$ mmHg
Air is made of a mixture of gases. the pressure that each gas exerts individually contributes to the total pressure of the system. The pressure that each gas exerts is the partial pressure of that gas which depends on the mole fraction of that gas or percentage composition of the individual gas.
Partial pressure of Oxygen - total pressure x percentage composition
Therefore pO₂ - $\frac{760 * 0.21}{3}$ = 53.2 mmHg
Answer is 53 mmHg
