What is the total air pressure at the top of the highest peak in the world

liberstina [14]

Answer:

At sea level, the atmospheric pressure would be a little over 100 kPa (one atmosphere or 760 mm Hg). If we climb to the top of Mount Everest (the highest mountain in the world at 29,029 feet or 8848 meters), the atmospheric pressure will drop to slightly over 30 kPa (about 0.30 atmospheres or 228 mm Hg).

Hydrogen reacts with nitrogen monoxide to form dinitrogen monoxide (laughing gas) according to the equation: H2O(g) + 2NO(g) rig

xxTIMURxx [149]

Answer:

A. $r=k[NO]^2[H_2]$

B. $k=0.121\frac{L^2}{mol^2*s}$

C. Second-order with respect to NO and first-order with respect to H₂

Explanation:

Hello,

In this case, for the reaction:

$H_2O(g) + 2NO(g) \rightarrow N_2O + H_2O(g)$

The rate law is determined by writing the following hypothetical rate laws:

$3.822x10^{-3}=k[0.3]^m[0.35]^n\\\\1.529x10^{-2}=k[0.6]^m[0.35]^n\\\\3.058x10^{-2}=k[0.6]^m[0.7]^n$

Whereas we can compute m as follows:

$\frac{3.822x10^{-3}}{1.529x10^{-2}} =\frac{[0.3]^m[0.35]^n}{[0.6]^m[0.35]^n} \\\\0.25=(0.5)^m\\\\m=\frac{log(0.25)}{log(0.5)} \\\\m=2$

Therefore, the reaction is second-order with respect to NO. Thus, for hydrogen, we find n:

$\frac{1.529x10^{-2}}{3.058x10^{-2}} =\frac{[0.6]^2[0.35]^n}{[0.6]^2[0.7]^n} \\\\0.5=(0.5)^n\\\\n=\frac{log(0.5)}{log(0.5)}\\ \\n=1$

A) Therefore, the reaction is first-order with respect to H₂. In such a way, we conclude that that the rate law is:

$r=k[NO]^2[H_2]$

B) Rate constant is computed from one kinetic data:

$k=\frac{1.529x10^{-2}\frac{mol}{L*s} }{(0.6\frac{mol}{L} )^2(0.35\frac{mol}{L})}\\\\k=0.121\frac{L^2}{mol^2*s}$

C. As mentioned before, reaction is second-order with respect to NO and first-order with respect to H₂.

Best regards.

Air is comprised predominantly of nitrogen (N2) and oxygen gas. The ambient air in this room contains about 0.28g of oxygen (O2)

viktelen [127]

Answer:

190 g

Explanation:

Knowing that:

O₂ gas in air: 0.28 g O₂ / L of air
Air inhaled at rest: 19.3 fl.oz. air / breath
Human takes 20 breaths / min

The grams of oxygen gas (O₂) that a human at rest inhales in 1 hour (60 minutes) will be calculated as:

grams of O₂ = breaths in 1 hour * air inhaled per breath * amount of O₂ in air

$grams O_{2} = 60 min* 20 \frac{breath}{min} * 19.3 \frac{fl.oz. air}{breath} * \frac{1 L}{33.814 fl.oz.} * 0.28 \frac{g O_{2} }{L}$

grams of O₂ = 191.78 g

190 g of O₂ are inhaled in 1 hour (written in correct number of significant figures)

*In the calculation the amount of air inhaled per breath was converted from fl.oz. to Liters knowing that <em>1 L = 33.814 fl.oz.</em>
