Answer:

The roasting process is a delicate combination of art and science . Roasters are familiar with how the beans look and the smells Well, familiarity with the machine makes things much easier to predict, but the best way is to do many different tests .Well, familiarity with the machine makes things much easier to predict, but the best way is to do many different tests.
Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy. It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.In zone refining, solutes are segregated at one end of the ingot in order to purify the remainder, or to concentrate the impurities. For example, in the preparation of a transistor or diode semiconductor, an ingot of germanium is first purified by zone refining.

Polling is the process where the computer or controlling device waits for an external device to check for its readiness or state, often with low-level hardware. For example, when a printer is connected via a parallel port, the computer waits until the printer has received the next character.

What is the frequency of a light that has a wavelength of 3.0 x 10 -7m?

alexdok [17]

Answer:

frequency of light (f) = 1 x 10¹⁵s⁻¹

Explanation:

Given Data:

Wavelength of light λ = 3.0 x10⁻⁷m

Frequency of light: to be calculated

Formula Used to find frequency:

f = V/λ ........................... (1)

where

f is the frequency

V is the velocity

λ is wavelength

Velocity of light = 3 x 10⁸ ms⁻¹

put the values in equation (1)

f = 3 x 10⁸ ms⁻¹ / 3.0 x10⁻⁷m

f = 1 x 10¹⁵s⁻¹

So the frequency of light = 1 x 10¹⁵s⁻¹

Elza [17]

Answer:

The Cape Horn was one of the most important routes for maritime trade, leading to sailing vessels.

the difficulty of all this is that it presents great iceberg and climatic factors that do not help the boats. nowadays other commercial routes were created that made this channel only be transited by larger ships, or oil tankers.

Explanation:

Sailing in its waters is still considered one of the greatest nautical challenges, so there are various sporting and tourist events that use this route, some as part of the circumnavigation of the globe, among which are important yacht regattas, such as the Vendée Globe.

4.The anticipated productof this electrophilic aromatic substitution reaction is 4-bromoacetanilide.a)From analysis of your IR s

Lady_Fox [76]

Answer:

Part a: The IR spectrum is not sufficient due to the similar radical group presence in both product and reactants.

Part b: Mass Spectrum data is required in addition to the IR data for confirming the presence of recrystallized product.

Part c: The additional data is consistent with the expectations as the data is in support of that.

Explanation:

Part a

Acetanilide has a characteristic IR peak at around 3100-3200 cm^-1 (N-H Stretching) and 1500-1680 cm^-1 (C=O Stretching). Since a similar radical group ( $NHCOCH_3$ ) is present in the 4-bromoacetanilide, thus it is difficult to affirm the presence of the product solely on the basis of IR spectrum.

Part b

Mass Spectral data will affirm the presence of recrystallized product with certainty.

Part c

4-bromoacetanilide will have $M^+$ peak at two points (213 & 215) corresponding to the two Bromine isotopes (79 & 81).

Also parent peak at 171 ( $M^+$ =43) will be in 49:51 due to presence of Bromine atoms.
