Provide the reagents necessary to carry out the following conversion. Group of answer choices KMnO4, NaOH,H2O KMnO4, H3O , 75oC
bonufazy [111]

Answer:

KMnO4,H3O^+,75°C

Explanation:

The conversion of cyclohexene to trans-1,2-cylohexanediol is an oxidation reaction. Alkenes are oxidized in the presence of potassium permanganate and acids to yield the corresponding diols.

These diols may also be called glycols. They are molecules that contain two -OH(hydroxyl) groups per molecule. The reaction closely resembles the addition of the two -OH groups of hydrogen peroxide to an alkene.

The bright color of potassium permanganate disappears in this reaction so it can be used as a test for alkenes.

Solid cesium iodide has the same kind of crystal structure as CsCl which is pictured below: If the edge length of the unit cell
Assoli18 [71]

The question is incomplete, here is the complete question:

Solid cesium iodide has the same kind of crystal structure as CsCl which is pictured below: If the edge length of the unit cell is 456.2 pm, what is the density of CsI in g/cm^3

The image is attached below.

<u>Answer:</u> The density of CsI is 9.09g/cm^3

<u>Explanation:</u>

To calculate the density of metal, we use the equation:

\rho=\frac{Z\times M}{N_{A}\times a^{3}}

where,

\rho = density

Z = number of atom in unit cell = 2  (BCC)

M = atomic mass of CsI = 259.8 g/mol

N_{A} = Avogadro's number = 6.022\times 10^{23}

a = edge length of unit cell = 456.2pm=456.2\times 10^{-10}cm    (Conversion factor:  1cm=10^{10}pm  )

Putting values in above equation, we get:

\rho=\frac{1\times 259.8}{6.022\times 10^{23}\times (456.2\times 10^{-10})^3}\\\\\rho=9.09g/cm^3

Hence, the density of CsI is 9.09g/cm^3

A stealth bomber is moving at 799km/h west and travels to a top velocity of 1,1325km/h west in 4.8 minutes.
maria [59]

Answer:

10.1 ms^-2

Explanation:

From;

v = u + at

v = final velocity

u = initial velocity

a= acceleration

t = time taken

To convert the velocity from Km/hr to m/s we us;

x * 1000/3600

Where x is the velocity in Km/hr

So;

799 * 1000/3600 = 221.9 m/s

11325 * 1000/3600 = 3145.8 m/s

4.8 minutes = 4.8 * 60 = 288 s

Applying the formula;

a= v - u/t

a = 3145.8 - 221.9/288

a = 10.1 ms^-2
