Why did construction of the Panama Canal become

sukhopar [10]

Answer:

(4) The navy needed a faster way to move ships between the Atlantic and Pacific Oceans.

Explanation:

The Panama Canal was an artificial eighty-two (82) kilometers water-way that connects the Atlantic Ocean with the Pacific Ocean in Panama and it enhanced maritime trades.

The construction of the Panama Canal became more important to the United States after the Spanish-American War because the navy needed a faster way to move ships

between the Atlantic and Pacific Oceans.

A tank at is filled with of dinitrogen monoxide gas and of boron trifluoride gas. You can assume both gases behave as ideal gase

blsea [12.9K]

Answer:

(1). Mole fraction = 0.152 for sulfur tetrafluoride gas.

Mole fraction = 0.848 For dinitrogen monoxide gas.

(2). Partial Pressure for dinitrogen monoxide gas = 187 kPa

Partial Pressure for sulfur tetrafluoride gas = 33.4 kpa.

(3). Total Partial Pressure = 220.4 kpa.

Explanation:

So, we are given the following data or parameters or information in the question above;

• Volume of the tank = 5.00L per tank;

• Temperature of the tank = 7.03°C;

• The mass of the content in the tank =

17.7g of dinitrogen monoxide gas and

7.77g of sulfur tetrafluoride gas.

So, we will be making use of the formulae below to calculate the MOLE FRACTION:

Moles, n= mass/molar mass and mole fraction = n(1)/ n(1) + n(2) per each constituents.

Moles, n1 = 17.7g of dinitrogen monoxide gas/ 44 grams per mole. =0.4023 moles.

Moles, n2 = 7.77g of sulfur tetrafluoride gas/ 108.1 grams per mole. = 0.07188 moles.

Total numbers of moles = n1 + n2 = 0.47415 moles

Mole fraction =0.4023 / 0.47415 = 0.848 of dinitrogen monoxide gas.

Mole fraction = 0.07188/0.47415 = 0.152 of sulfur tetrafluoride gas.

PART TWO: CALCULATE THE PARTIAL PRESSURE AND TOTAL PRESSURE BY USING THE FORMULA BELOW;

pressure × volume = number of moles × gas constant, R × temperature.

Pressure = n × R × T/ V.

For dinitrogen monoxide gas. ;

Partial Pressure = 0.4023 × 8.314 × 280.03 / 5 × 10^-3 = 187 kPa.

For sulfur tetrafluoride gas

Partial Pressure = 0.07188 × 8.314 ( × 280.03 / 5 × 10^-3. = 33.4 kpa.

(3). Total pressure = (187 + 33.4)kpa = 220.4 kpa

A container holds 6. 4 moles of gas. Hydrogen gas makes up 25% of the total moles in the container. If the total pressure is 1.

ipn [44]

In a mixture of gases, the total pressure is equivalent to the aggregate of all the partial pressures of the single element of the gas.

It can be written as $\rm P _{total}$ = P₁ + P₂ + P₃ and so on.

The partial pressure will be:

Option A. 0. 31 atm

Pressure can be estimated by:

$\rm P_{total} = \dfrac{n _{total }RT}{ V}$

$\rm P_{total} = \dfrac{n _{H_{2}} + n _{\rm other \;gases}}{ V}$

Where,

$\rm nH_{2} = 25\% \times n_{Total}$

And,

$\begin{aligned}\rm P_{H_{2}} &= 25\% \times \rm P_{Total}\\\\& = 25\% \times 1.24 \;\rm atm\\\\& = 1.24 \rm \;atm \times 25 \end{aligned}$

Solving finally we get,

$\rm P_{H_{2}} = 0.31 \;\rm atm$

Therefore, 0.31 atm is the partial pressure of the hydrogen gas.

Hello, and this is my own words Periodic trends are specific patterns in the properties of chemical elements that are revealed in the periodic table of elements. Major periodic trends include electronegativity, ionization energy, electron affinity, atomic radii, ionic radius, metallic character, and chemical reactivity.

Hope This Helps. and have good day!
