Answer:

The pressure inside the cylinder is [tex]8.327\times 10^{-3}[/tex] atmospheres.

The value for R for this problem is 0.082 atmosphere-liters per mol-Kelvin.

Explanation:

Let suppose that helium gas inside the cylinder behaves as an ideal gas, the equation of state for the ideal gas is:

[tex]P\cdot V = n\cdot R_{u}\cdot T[/tex] (1)

Where:

[tex]P[/tex] - Pressure, measured in atmospheres.

[tex]V[/tex] - Volume, measured in liters.

[tex]n[/tex] - Molar quantity, measured in moles.

[tex]T[/tex] - Temperature, measured in Kelvin.

[tex]R_{u}[/tex] - Ideal gas, measured in atmosphere-liters per mole-Kelvin.

If we know that [tex]V = 60\,L[/tex], [tex]n = 0.020\,mol[/tex], [tex]T = 304.65\,K[/tex] and [tex]R_{u} = 0.082\,\frac{atm\cdot L}{mol\cdot K}[/tex], then the pressured inside the cylinder is:

[tex]P = \frac{n\cdot R_{u}\cdot T}{V}[/tex]

[tex]P = \frac{(0.020\,mol)\cdot \left(0.082\,\frac{atm\cdot L}{mol\cdot K}\right)\cdot (304.65\,K) }{60\,L}[/tex]

[tex]P = 8.327\times 10^{-3}\,atm[/tex]

The pressure inside the cylinder is [tex]8.327\times 10^{-3}[/tex] atmospheres.

The value for R for this problem is 0.082 atmosphere-liters per mol-Kelvin.

Answer:

It is an Alkaline Earth Metal

Explanation:

Metallic bonding results from the delocalization of electrons from the parent metal atom so that positive ions are conceived to swim in a sea of electrons. This view of metallic bonding accounts for the malleability, and ductility of metals, as well as their properties of thermal and electrical conduction.

Each plant organ (roots, stems, leaves) contains all three tissue types: ... Vascular tissue is made of two specialized conducting tissues: xylem and phloem. Xylem tissue transports water and nutrients from the roots to different parts of the plant, and also plays a role in structural support in the stem

Answer:

Acting like a highly reflective blanket, the cryosphere protects Earth from getting too warm. Snow and ice reflect more sunlight than open water or bare ground. Changes in snow and ice cover affect air temperatures, sea levels, ocean currents, and storm patterns all over the world.

Explanation: Hope this answers your question

When the North Pole of one bar magnet is near the South Pole of another bar magnet, they will attract each other. So, the correct option is C, attraction. This is because opposite magnetic poles attract each other, while like magnetic poles repel each other.

A magnetic field is a region in space where a magnetic force can be detected. It is created by the movement of charged particles, such as electrons, protons, and ions. A magnetic field can be produced by a magnet, an electric current, or a changing electric field.

When the North Pole of one bar magnet is near the South Pole of another bar magnet, they will attract each other. This is because the magnetic field lines of the two magnets interact in such a way that they try to align with each other. Since opposite magnetic poles attract each other, the North Pole of one magnet will be attracted to the South Pole of the other magnet.

The magnetic force between the two magnets depends on the strength of the magnetic field and the distance between the magnets. The closer the magnets are, the stronger the magnetic force will be.

Therefore option C, attraction is correct.

Answer:

Thomson's plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged "soup." Rutherford's gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus. Based on these results, Rutherford proposed the nuclear model of the atom.
