Suppose two 200.0-L tanks are to be filled separately with the gases helium and hydrogen. What mass of each gas is needed to pro

Aneli [31]

Answer:

Mass of helium = 4426.9524 g

Mass of hydrogen gas = 2213.4762 g

Explanation:

Pressure = 135 atm

Temperature = 24 °C

Volume = 200 L

Number of moles = ?

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15

So,

T₁ = (24 + 273.15) K = 297.15 K

Using ideal gas equation as:

PV=nRT

where,

P is the pressure

V is the volume

n is the number of moles

T is the temperature

R is Gas constant having value = 0.0821 L.atm/K.mol

Applying the equation as:

135 atm × 200 L = n × 0.0821 L.atm/K.mol × 297.15 K

⇒n = 1106.7381 moles

<u>For helium gas:</u>

Molar mass = 4 g/mol

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$1106.7381= \frac{Mass}{4}$

$Mass= 4426.9524\ g$

<u>For hydrogen gas:</u>

Molar mass = 2 g/mol

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$1106.7381= \frac{Mass}{2}$

$Mass= 2213.4762\ g$

What is responsible for changes in the state of matter?

NeX [460]

Answer:

Temperature and pressure are the two factors which are responsible for change in state of matter.

Solid – In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. ... In the solid the particles vibrate in place. Liquid – In a liquid, particles will flow or glide over one another, but stay toward the bottom of the container.

The reaction of hydrogen gas with oxygen gas is what type of reaction precipitation single replacement

Oksi-84 [34.3K]

The reaction of hydrogen gas (H2) with oxygen gas (O2) is a COMBINATION or SYNTHESIS reaction, because multiple substances combine to form fewer substances. Here, the two gases form one substance, water (H2O):
2H2 + O2 -- > 2H2O

If 40 grams of pentane are burned, how many grams of oxygen are needed ?

Helga [31]

1) Molar mass C5H12= 5*12 +1 *12=60+12=72 g/mol
2) 40g C5H12 * 1 mol C5H12/72 g C5H12 = 40/72 mol C5H12
3)     C5H12 + 8O2 ------> 5CO2 + 6H2O
by reaction     1 mol 8 mol
from problem    40/72 mol x mol

x=(40/72) * 8/1=(40*8)/72=(40)/9 mol O2
4) M(O2)=2*16 g/mol =32 g/mol
5) (40)/9 mol O2 *(32 g O2/ 1 mol )=(40 * 32)/9 =142.2 g O2
