A test of an automobile engine’s exhaust revealed that 3.5 g of NO2 was emitted in 10. minutes of operation. How many moles of N

O2 would this engine release if it were used for a 40.-minute commute, assuming that this measured number is representative of the emission under all circumstances?

Answer:

0.304 moles of NO₂ may be produced

Explanation:

During 10 minutes of operation, 3.5 g of NO₂ were produced by the engine.

In 40 minutes, the engine may produce (40 . 3.5)/ 10 = 14 g of gas

Solved by a rule of three.

Let's convert the mass to moles → 14 g . 1 mol/ 46 g = 0.304 moles

Zarrin [17]

Iron is the very last product in stellar fusion is that; Iron has a tightly bound nucleus, and atoms larger than iron are less stable and tend to undergo nuclear fission.

The stability of an atom is dependent on the binding energy per nucleon of the atom.

The binding energy per nucleon of elements increases steadily until iron, we can see that from the curve very easily.

Beyond iron, we have exceeded the region of stable binding energy per nucleon of atoms. The atoms after iron in the curve are mostly unstable heavy nuclei.

If 1.6 moles of an ideal gas are at a temperature of 25c and a pressure of 0.91 atm hg, what volume would the gas occupy, in lit
Fiesta28 [93]
From\ Ideal\ Gas\ Law:\\\\PV=nRT\\\\
P-pressure\\V-volume\\n-number\ of\ moles\\R- universal\ gas\ constant\\T-absolute\ tmeperature\\\\
R=\ 8,3145J/ mol\ K\\P=0,91atm\\
n=1,6moles\\T=25c\\\\
Converting\ units:\\\\
1atm=101,3kPa=101,3*10^3\\
0,91atm=0,91*101,3*10^3=92,183*10^3Pa\\T=25c=273+25=298K\\\\
V=\frac{nRT}{P}=\frac{1,6*8,3145*298}{92183}=0,043m^3=43liters\\\\Answer\ is\ 43\ liters.
