Well 1.28 mol of H2S will be produce but it didn't said anything about that where the experiment happens (in STP situation (which seems not to be true ) or not )

Azobisisobutyronitrile (AIBN) is commonly used as a radical initiator. Use correct arrow formalism to show this process.
Dahasolnce [82]

Answer: AIBN is good radical initiator

Explanation:

A radical in organic chemistry refers to any specie having a single unshared electron. An initiator is any specie capable of producing radicals thus starting up a chain reaction. Azobisisobutyronitrile is a good initiator basically owing to its structure. It forms radicals by breaking up to release nitrogen gas as shown in the image attached. The two radicals formed both contain the -CN group which stabilizes the radical.

Americium-241 is used in some smoke detectors. It is an alpha emitter with a half-life of 432 years. How long will it take in ye
Dmitrij [34]

It will take 497.67 years to decay.

What is half-life ?

The duration needed for a quantity to decrease to half of its initial value is known as the half-life. In nuclear physics, the phrase is frequently used to indicate how rapidly unstable atoms decay radioactively or how long stable atoms last. The phrase is also used more broadly to describe any kind of exponential decay (or, very infrequently, nonexponential decay). The biological half-life of medications and other compounds in the human body, for instance, is a term used in the medical sciences. Half-opposite life's in exponential growth is time's doubling.

The formula

At = (Ao)(0.5)(t/h)

where Ao is the initial amount determines the amount of material at a specific time t, At, with a half-life of h.

At/Ao = 0.45 from the stated results in (0.5)(t/432).

T in the equation has a value of 497.67 years.
