Can you please help me with this lab.

A number of compounds containing the heavier noble gases, and especially xenon, have been prepared. One of these is xenon hexafl

aalyn [17]

Answer:

The answer is "82.2 torr"

Explanation:

moles of Xe:

$= \frac{0.06}{131.293} \\\\ =0.00045699313 \ \mol$

moles of $F_2$ :

$= \frac{0.0274}{38} \\\\= 0.00072105263\ \ mol$

moles of produced $XeF_2:$

$= 0.00024$

moles of left $Xe$ :

$= 0.00021$

Calculate the Pressure:

$= \frac{(0.08206\times 0.00024 \times 293)}{(.1)} + \frac{(0.08206\times 0.00021 \times 293)}{(.1)} \\\\= 0.10819611 \ \ atm \\\\ = 0.10819611 \times 760 \\\\ = 82.2 \ \ torr$

You can increase the rate solute dissolves in solvent by______

V125BC [204]

Crushing particles of solute. The more surface area of the solute exposed to the solvent the faster the solute will dissolve and react with the solvent

A mountain lion jumps to a height of 3.25 m when leaving the ground at an angle of 43.2°. What is its initial speed (in m/s) as

miss Akunina [59]

Recall that

${v_f}^2={v_i}^2+2a\Delta y$

where $v_i$ and $v_f$ are the lion's initial and final vertical velocities, $a$ is its acceleration, and $\Delta y$ is the vertical displacement.

At its maximum height, the lion has 0 vertical velocity, so we have

$0={v_i}^2-2gy_{\rm max}$

where <em>g</em> is the acceleration due to gravity, 9.80 m/s², and we take the starting position of the lion on the ground to be the origin so that $\Delta y=y_{\rm max}-0=y_{\rm max}$ .

Let <em>v</em> denote the initial speed of the jump. Then

$v_i=v\sin(43.2^\circ)=\sqrt{2\left(9.80\dfrac{\rm m}{\mathrm s^2}\right)(3.25\,\mathrm m)}\implies\boxed{v\approx11.7\dfrac{\rm m}{\rm s}}$

What characteristics of EM waves did you discover?

jarptica [38.1K]

The characteristics of electromagnetic waves typically represent as follows:

There are changes in the electric and magnetic fields simultaneously so that both fields have maximum and minimum values at the same time and place.
The direction of the electric field and the magnetic field are perpendicular to each other. The direction of both is perpendicular to the direction of the wave propagation.
The shape of electromagnetic waves is transverse waves.
It has general wave characteristics like polarization, reflection, refraction, interference, and diffraction.
The amount of the electric field (E) is directly proportional to the magnitude of the magnetic field, with the relationship E = cB.
The universal constant of the velocity of electromagnetic waves in a vacuum is $\boxed{ \ c = 3 \times 10^8 \ m/s. \ }$
The speed at which electromagnetic waves propagate depends merely on the electrical and magnetic properties of the medium that it travels on.
Because electromagnetic waves do not contain an electric charge, they do not experience any possible deviation in the electric or magnetic fields.

<h3>Further explanation</h3>

Two physicists who contributed significantly to developing the concept of electromagnetic waves are Faraday and Maxwell around 1831-1864.
From the observations, Faraday suggested that changes in the magnetic field cause an electric charge to flow in the loop of wire, contributing in the emergence of an electric field.
Maxwell proposed a reverse process, which is a change in the electric field will generate a magnetic field.
As follows, according to Faraday's Law, changes in sinusoidal magnetic fields generate electric fields which also change sinusoidally.
Meantime, according to Maxwell's Hypothesis, changes in sinusoidal electric fields generate magnetic fields which also change sinusoidally.
Furthermore, there is a process of combining electric and magnetic fields that propagate in all directions called electromagnetic waves.
