In an airplane, a gas sample occurs at a volume of 1.5 L at 760.0 torr. Suppose, while flying, the airplane loses pressure and t

jekas [21]

Answer:

100 torr

Explanation:

First find the formula you need to use, this will be...

P2 = V1 x P1 / V2

Next, fill in the numbers, this will be...

P2 = ? (we are trying to find this)

P1 = 760 torr

V1 = 1.5 L

V2 = 11.4 L

Next, turn into new formula (just rearrange)

P2 = 1.5 L x 760 torr / 11.4 L

Next, do the math. This should get you...

<u>100 torr</u> as your answer

- Let me know if you need more help understanding. I would be glad to further explain or do more problems.

Ammonium nitrate, a common fertilizer, is used as an explosive in fireworks and by terrorists. It was the material used in the t

Sladkaya [172]

Explanation:

The given balanced reaction is as follows.

$2NH_{4}NO_{3} \rightarrow 2N_{2} + O_{2} + 4H_{2}O$

It is given that mass of ammonium nitrate is 86.0 kg.

As 1 kg = 1000 g. So, 86.0 kg = 86000 g.

Hence, moles of $NH_{4}NO_{3}$ present will be as follows.

Moles of $NH_{4}NO_{3}$ = $\frac{mass given}{\text{molar mass of NH_{4}NO_{3}}}$

= $\frac{86000 g}{80.043 g/mol}$

= 1074.42 mol

Therefore, moles of $N_{2}$ , $O_{2}$ and $H_{2}O$ produced by 1074.42 mole of $NH_{4}NO_{3}$ will be as follows.

Moles of $O_{2}$ = $\frac{1}{2} \times 1074.42 mol$

= 537.21 mol

Moles of $N_{2}$ = $\frac{2}{2} \times 1074.42 mol$

= 1074.42 mol

Moles of $H_{2}O$ = $\frac{4}{2} \times 1074.42 mol$

= 2148.84 mol

Therefore, total number of moles will be as follows.

537.21 mol + 1074.42 mol + 2148.84 mol

= 3760.47 mol

According to ideal gas equation, PV = nRT. Hence, calculate the volume as follows.

PV = nRT

1 atm \times V = 3760.47 mol \times 0.0821 L atm/mol K \times 580 K[/tex] (as $307^{o}C$ = 307 + 273 = 580 K)

V = 179066.06 L

Thus, we can conclude that total volume of the gas is 179066.06 L.

What do you think could happen with methane gas and CO 2

Molodets [167]

Answer:

these gases accumulate in the atmosphere and create the heat-reflective layer that keeps the Earth at a livable temperature. These gases form the insulation that keeps the planet warm enough to support life

Oxygen gas is collected at a pressure of 1.21 atm in a container which has a volume of 10.0 L. What temperature (in Kelvin) must

stiv31 [10]

Answer : The temperature of gas is, 295 K

Explanation :

To calculate the temperature of gas we are using ideal gas equation:

$PV=nRT$

where,

P = Pressure of gas = 1.21 atm

V = Volume of gas = 10.0 L

n = number of moles = 0.500 mole

R = Gas constant = $0.0821L.atm/mol.K$

T = Temperature of gas = ?

Now put all the given values in above equation, we get:

$1.21atm\times 10.0L=0.500mole\times (0.0821L.atm/mol.K)\times T$

$T=294.8Kapprox 295K$

Therefore, the temperature of gas is, 295 K
