Although birds' eggs appear to be fragile, they are in fact extremely robust. The oval shape applies the same rules of engineering as an arched bridge; the convex surface can withstand considerable pressure without breaking.

There is a mixture of three gases. We know the total pressure is 2.50 atmosphere and the pressure of the oxygen and the nitrogen

Viktor [21]

Answer:

1.14 atm and 1.139 mol

Explanation:

The total pressure of the container is equal to the sum of the partial pressure of the three gasses:

P = Poxygen + Pnitrogen + Pcarbon dioxide

2.50 atm = 0.52 + 0.84 + Pcarbon dioxide

Now we solve for the pressure of carbon dioxide:

Pcarbon dioxide = 1.14 atm

To calculate the number of CO₂ moles we use PV=nRT:

P = 1.14 atm

V = 25.0 L

n = ?

R = 0.082 atm·L·mol⁻¹·K⁻¹

T = 32 °C ⇒ 32 + 273.16 = 305.16 K

1.14 atm * 25.0 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 305.16 K

n = 1.139 mol

Use the drop-down menus to select the correct name for each of the organic compounds.

Molodets [167]

Answer:

Here's what I get

Explanation:

CH₃CH₂CH₂CH₂CH₂CH₃ — hexane

CH₂=CHCH₂CH₂CH₂CH₃ — hex-1-ene is the preferred IUPAC name (PIN). 1-Hexene is accepted

CH₃C≡CCH₃ — but-2-yne (PIN); 2-butyne is accepted

CH₃CH(CH₃)CH₂CH₂CH₃ — 2-methylpentane

CH₃CH₂CHCICH₂CH₃ — 3-chloropentane
