Bromine and chlorine easily react with alkenes in addition reactions. This experiment involves brominating trans-stilbene with a 10% bromine dichloromethane solution. As a result, an addition reaction occurs, and 1,2-dibromo-1,2-diphenylethane is formed.

Step-by-step explanation:

stilbene + Br2  ---->  PRODUCT(dibromostilbine)

No of moles of stilbene = 0.55/180.25 = 0.00305 mole

limiting reagent = stilbene

so that,

No of moles of  PRODUCT = 0.00305 mole

massof product produced  = 0.00305*260.25  = 0.793 gram

Theoretical yield = 0.793 gram

dibromostilbine molarmass  = 260.25 g/mol

practical yield  = 0.68grams

percent yield  = practical yield /Theoretical yield *100

               = 0.68/0.793*100 = 85.75%

Trans-stilbene acts as a nucleophile, while bromine acts like an electrophile. As a result, the bromine reagent electrophilically adds to the nucleophilic double bond. The Br-Br bond becomes polarized, and the more positively charged Br atom is transferred to the alkene, resulting in the formation of a bromonium ion.

Bromine addition begins on one side of the double bond (either side is equally likely, but only one option is chosen) and is followed by bromide ion attack on bromonium ion (again, attack could occur by carbon because the ion is symmetric, but only one option drawn). As shown above, the end result is a trans dibromide.

It can be inferred from the above that "Neither Technician A nor B is correct" (Option D). Note that blending an undamaged vehicle panel is required when there is very minimal damage or dent to the panel. In this case, the technician utilizes filling, spraying, and polishing to hide the dent. This is standard practice and is not considered fooling the customer.

When repairing a minor dent in a panel, the "blend inside panel" approach is frequently utilized. Blending is a method used on a non-repaired, undamaged panel to eliminate color differences between a refinished panel and the existing paint on surrounding panels.

The most typical blending process seen on insurance quotes is on bumpers and doors. Insurers pay half the restore time and then approve full clear, significantly cutting refinishing time by an hour for each repair.

From a 320-grit completed mended area, the repaired area still has to be brought up to refinish requirements.

Not only has a part of the refinish time been wasted, but extra operations are required to restore the panel to its original, undamaged state. Most estimate P pages include refinishing timelines for fresh, undamaged panels, rather than those that require preparation.

Technician A is correct that bearings have a soft surface that flows away from high spots in case of a nick in the crankshaft.

In order to transform the reciprocating action of a piston engine into rotating motion, a crankshaft is a mechanical component used. The pistons are propelled by the connecting rods through the crankshaft, which is a rotating shaft with one or more crankpins. The internal combustion engine's main structural support comes from the crankshaft. The engine's correct operation and the transformation of a linear motion into a rotating motion are both handled by the crankshaft. To provide a long service life, crankshafts should have exceptionally high wear and fatigue resistance. The reciprocating motion of the pistons is transformed into rotational motion by a crankshaft, which is a spinning shaft. Commonly utilized in internal combustion engines, crankshafts are made up of a number of cranks and crankpins to which the connecting rods are fastened.

What is transistor?
The semiconductor device known as a transistor is used to switch or amplify electrical impulses. The transistor is one of the fundamental components of contemporary electronics. It has at least three terminals for connecting to an electronic circuit and is made of semiconductor material. The current flowing through another pair of a transistor's terminals is controlled by the voltage or current provided to one set of those terminals. A transistor can magnify a signal because the regulated (output) power can be greater than that of the controlling (input) power. Although many more transistors are found embedded in integrated circuits, some are packaged individually. Julius Edgar Lilienfeld, an Austro-Hungarian physicist, first presented the idea of a field-effect transistor around 1926, but it was not feasible to create a functional device at that time.

Both Technicians A and B are accurate when they say that disc brake rotors can be either hub-style or hubless-style.

With disc brakes, the brake pads attached to the brake callipers grip on the rotating braking rotors to stop or slow down the wheels. Friction is created by the brake pads pressing against the rotors, which turns kinetic energy into heat energy.

Although this thermal energy produces heat, it may be effectively dispersed since the primary components are exposed to the environment. This ability to dissipate heat lessens brake fade, a condition where heat affects how well a vehicle brakes. The resistance of disc brakes to water fade, which happens when water on the brakes considerably lowers braking force, is another benefit. The rotor spins rapidly as the car is moving, and this rotational motion discharges the water from the rotors themselves, resulting in stable braking force.

Fine grained of alkali igneous rocks cannot be used in cement because of the volume expansion caused by the Alkali-silica reaction, fine-grained igneous rocks cannot be used as aggregates in cement.

Extrusive igneous rocks have a fine-grained or aphanitic texture, with grains that are too small to see without a magnifying glass. The fine-grained texture suggests that the rapidly cooling lava did not have enough time to form large crystals. A petrographic microscope can be used to examine these tiny crystals.

The texture of an igneous rock (fine-grained vs coarse-grained) is determined by the rate at which the melt cools: slow cooling produces large crystals, while fast cooling produces small crystals.

The 3-stage parametric equalizer adjustments on a Yaesu FT-DX10 are high frequency, middle frequency, and low frequency.

What is parametric equalizer?
This illustration demonstrates how to create parametric equalizer filters. Digital filters known as parametric equalisers are used in audio to modify the frequency content of a sound input. By permitting adjustments to the gain, centre frequency, and bandwidth of each filter, parametric equalisers offer capabilities beyond those of graphic equalisers. Graphic equalisers, on the other hand, only let you change the gain of the each filter. Typically, second-order IIR filters are used to create parametric equalisers. These filters have the issue of having relatively wide ripple or transition areas due to their low order, and when multiple of them are combined in a cascade, they may overlap. The ability to create high-order IIR parametric equalisers is provided by Audio ToolboxTM. Such high-order designs provide each filter's shape much greater flexibility.

Assuming demand paging with three frames, the number of page faults that would occur for the following replacement algorithms are:

Demand paging is a way of managing virtual memory in computer operating systems. In a demand paging system, the operating system transfers a disk page into physical memory only if it is attempted to be accessed and the page is not already in memory.

The LRU page replacement method creates a new page by replacing the least recently used page in memory. The LRU page replacement technique is based on the idea that the least recently used page in memory will not be utilized for a long period.

The most basic page replacement technique is the FIFO Replacement Algorithm. In this technique, the operating system maintains a list of all pages in memory in a queue, with the oldest page at the top.

A regular expression is a string of characters that specifies a text search pattern. String-searching algorithms typically use such patterns for "find" or "find and replace" operations on strings, as well as input validation. In theoretical computer science and formal language theory, regular expression techniques are developed.

SA=\epsilon (Eqaution 1)

SB=SB(0)+SB(1)+SB(2)  + SA(0) + SA(1) (Eqaution 2)

SC=SA(2)+SD(2)+SC(2) (Eqaution 3)

SD=SC(0+1) + SD(0+1) (Eqaution 4)

Using arden's expression on equation 5 we can write it as:

SD=SC(0+1)(0+1)* (Equation 5)

We need to find SC to get the regular expression as it is the final state.

We substitute equations into one another to get the answers.

Substituting Equation 1 to equation 3 we get:

SC=\epsilon(2) + SD(2) + SC(2)

SC = (2+SD(2)) + SC(2)

Substituting Equation 5 into it we get:

SC=2+SC(0+1)(0+1)*2+SC(2)

SC=2+SC((0+1)(0+1)*2+2)

Using arden's therorem we can write it as:
