What mineral has the least hardness according to the scale?

kenny6666 [7]

The softest mineral in the Mohs Hardness Scale is talc.
Talc is often used in baby powder and corn starch, among other things. Talc cleaves into thin sheets, and it is held together only by van de Waals bonds, which allows these sheets to slip past each other. This gives the mineral its softness and it is often valued as a high-temperature lubricant.

The target diol is synthesized in one step from 1-methylcyclopentene, but your lab partner exhausted the supply of that alkene.

andrezito [222]

Answer:

The reagents are $CH_{3}CH_{3}O^{-},OsO_{4},NaHSO_{3}and H_{2}O$ .

Explanation:

1-Methylenecyclopentene is treated with HBr form 1-bromo-1-methylcyclopentane, which is treated with strong base ethoxide ion and forms 1-methylcyclopent-1-ene.

This alkene is treated with osmium tetraoxide in the presence of sodium bisulfite to form target product.

The chemical reaction is as follows.

¿Cuántos moles de bióxido de Nitrógeno (NO 2) se forman cuando reaccionan 5 moles de Nitrógeno (N 2)?

o-na [289]

Answer:

10 moles de NO2

Explanation:

Tenemos la ecuación de la reacción como sigue;

N2 (g) + 2 O2 (g) → 2 NO2 (g)

Asi que;

Si 1 mol de nitrógeno produce 2 moles de NO2

5 moles de nitrógeno producirán 5 * 2/1 = 10

Por tanto, se producen 10 moles de NO2 moles

The mass defect for the formation of lithium-6 is 0.0343 g/mol. The binding energy for lithium-6 nuclei is ________ kJ/mol. Ente

Sholpan [36]

<u>Answer:</u> The binding energy for lithium-6 nuclei is 3.09 E+11

<u>Explanation:</u>

Binding energy is defined as the energy which holds the nucleus together. It is basically the product of mass defect and the square of the speed of light.

This energy is calculated by using Einstein's equation, which is:

$E=\Delta mc^2$
