7. Assume that you have collected 867 L of nitrogen gas at STP. What is the mass of the nitrogen gas?
jekas [21]

Answer:

1083.6 g

Explanation:

At STP, 1 mol of any given mass will occupy 22.4 L.

With the information above in mind we can<u> calculate how many moles of nitrogen gas (N₂) are there in 867 L</u>:

  • 867 L ÷ 22.4 L/mol = 38.7 mol

Finally we convert 38.7 moles of N₂ into grams, using its molar mass:

  • 38.7 mol * 28 g/mol = 1083.6 g

Identify the combustion reaction
TiliK225 [7]

Answer:

C₄H₁₂ + 7O₂ --> 4CO₂ + 6H₂O

Explanation:

Organic molecules react with O2 to create water and CO2 in combustion processes. C4H12 is an organic molecule that combines with O2 to create water and CO2 as shown in the reactions.

As a result, this is the sole reaction that obeys the general combustion equation.

The first four planets in our solar system are rocky. How does that relate to Newton’s law of universal gravitation?
Serhud [2]

Explanation:

According to Newton law of gravity, the strength of gravitational pull between two objects is related to their masses, directly, and inversely by the distance between them;

F = G * (M₂ – M₁) / d where;

F – the force of gravity

G – gravitational constant

M₂ – the mass of one object

M₁ – the mass of the other object

d – the distance between the two objects

The rocky planets have a higher mass than the gas planets hence will be strongly ‘feel’ the gravitational pull of the star in the solar system revolves about.  This is why rocky planets are closer to their star while gas planets are towards the outer edges.

Use the data provided to calculate benzaldehyde's heat of vaporization smartwork5
QveST [7]
This problem is incomplete. Luckily, I found a similar problem from another website shown in the attached picture. The data given can be made to use through the Clausius-Clapeyron equation:

ln(P₂/P₁) = (-ΔHvap/R)(1/T₂ - 1/T₁)

where
P₁ = 14 Torr * 101325 Pa/760 torr = 1866.51 Pa
T₁ = 345 K
P₂ = 567 Torr * 101325 Pa/760 torr = 75593.78 Pa
T₂ = 441 K

ln(75593.78 Pa/1866.51 Pa) = (-ΔHvap/8.314 J/mol·K)(1/441 K - 1/345 K)
Solving for ΔHvap,
<em>ΔHvap = 48769.82 Pa/mol or 48.77 kPa/mol</em>
