Drilling is an example of what type of manufacturing process?

20. What is a "whipping motion and why is it used?

Reptile [31]

Whipping is done in a forward direction. You deposit a dab or puddle of metal down, and then whip the rod forward and up a little to let that dab cool a bit, then you move back and deposit another dab slightly ahead of the previous dab.
Cellulose rod like 6010 and 6011 are known as "fast freeze" electrodes, also known to be deep penetrating rods. The "whip and stitch" motion is used so that you get the full benefit of the cellulose characteristics. The forward motion basically gouges out the base metal, and it gets filled in with the back-step.
Hope this helped:)

What is the standard half-cell potential for the oxidation of methane under acidic conditions? The reaction for methane is as fo

Yuri [45]

Answer:

The element that is oxidized is carbon.

Its oxidation state increased. It increased from -4 to +4

Explanation:

Oxidation is a process that involves increase in oxidation number.

The oxidation number of carbon in CH4 is -4

C + (1×4) = 0

C + 4 = 0

C = 0 - 4 = -4

The oxidation number of carbon in CO2 is +4

C + (2×-2) = 0

C - 4 = 0

C = 0+4 = 4

Increase in the oxidation number of carbon from -4 to +4 means carbon is oxidized

Consider a cubic crystal with the lattice constant a. Complete the parts (a)-(c) below. (a) Sketch the crystallographic planes w

Anna [14]

Answer:

(a) See attachment

(b) The two planes are parallel because the intercepts for plane [220] are X = 0,5 and Y = 0,5 and for plane [110] are X = 1 and Y = 1. When the planes are drawn, they keep the same slope in a 2D plane.

(c) $d = \frac{a}{\sqrt{h^{2} + k^{2} + l^{2}}} = \frac{1}{\sqrt{2}} = 0,707$

Explanation:

(a) To determine the intercepts for an specific set of Miller indices, the reciprocal intercepts are taken as follows:

For [110]

$X = \frac{1}{1} = 1; Y = \frac{1}{1} = 1; Z = \frac{1}{0} = \inf.$

For [220]

$X = \frac{1}{2} = 0,5;Y = \frac{1}{2} = 0,5;Z = \frac{1}{0} = \inf.$

The drawn of the planes is shown in the attachments.

(b) Considering the planes as two sets of 2D straight lines with no intersection to Z axis, then the slope for these two sets are:

For (1,1):

$K_1 = \frac{1}{1} = 1$

For (0.5, 0.5):

$K_2 = \frac{0.5}{0.5} = 1$

As shown above, the slopes are exactly equal, then, the two straight lines are considered parallel and for instance, the two planes are parallel also.

(c) To calculate the d-spacing between these two planes, the distance is calculated as follows:

The Miller indices are already given in the statement. Then, the distance is:

$\frac{1}{d^{2}} = \frac{h^{2} + k^{2} + l^{2}}{a^{2}}$

$d = \frac{a}{\sqrt{h^{2} + k^{2} + l^{2}}} = \frac{1}{\sqrt{2}} = 0,707$

Select the correct answer.

melomori [17]

Answer:

starburst

Explanation:

There are many different kinds of "hazard symbols," which are being used in order for people to recognize what kind of material they are handling. When it comes to "pictograms," the symbol for a hazard class of explosive is an exploding bomb that shows a starburst effect. An example of such chemical is the "organic peroxide" and other self-reactive chemicals.

A "flame" is a hazard symbol for flammable substances. A "gas cylinder" is a hazard symbol for gases that are located in containers that are under pressure. A "test tube" is a hazard symbol for substances/materials that cause corrosion to skin.
