Iron is the heaviest element produced in large stars by nuclear fusion near the end of their life cycle .
<h3>What do you mean by the nuclear fusion ?</h3>
Nuclear fusion is the process by which two light atomic nuclei combine to form a single heavier one while releasing massive amounts of energy.
The main advantage of nuclear fusion is it is safe source for the generation of electricity.
Characteristics of nuclear fusion -:
- The main characteristic of nuclear fusion is that it involves formation of a singular particle from two or more atoms.
- Unlike nuclear fission, nuclear fusion is common in nature- just hard to recreate.
- Nuclear fusion typically produces few radioactive particles .
- Fusion works by applying a great deal of pressure to overcome .
Hence ,Iron is the heaviest element produced in large stars by nuclear fusion near the end of their life cycle .

The answer is diamagnetism. It is a significant mechanical
effect that happens in all materials; when it is the only influence to the
magnetism, the material is named diamagnetic. Quartz and water are samples
of diamagnetic materials. The diamagnetic influence
is usually unimportant in materials holding strong lasting magnetic moments.
The answer is Aphelion since that is the point in a planet, comet or asteroids orbit around a sun when it is furthest
Answer:
An SCl2 molecule has <u>polar</u> bonds and a <u>bent angular</u> molecular shape. As a result, an SCl2 molecule is <u>polar.</u>
Explanation:
It is a covalent compound made up of angular molecules that contain two chlorine atoms attached to one sulfur atom. Sulfur undergoes sp3 hybridization and has two pairs of nonbonding electrons. Given their geometry and the difference in electronegativity between chlorine and sulfur, they are molecules with a marked polar character. The bond angle between the sulfur atom and the two chlorine atoms is 109.5°, since the two vectors are of equal intensity but their directions do not coincide; if they are added vectorially, they do not cancel each other out, making the molecule polar.
Answer:
-79.8 × 10⁴ J/mol
Explanation:
<em>Arsine, AsH₃, is a highly toxic compound used in the electronics industry for the production of semiconductors. Its vapor pressure is 35 Torr at 111.95 °C and 253 Torr at 83.6 °C.</em>
<em />
Then,
P₁ = 35 torr
T₁ = 111.95 + 273.15 = 385.10 K
P₂ = 253 torr
T₂ = 83.6 + 273.15 = 356.8 K
We can calculate the standard enthalpy of vaporization (ΔH°vap) using the two-point Clausius-Clapeyron equation.
where,
R is the ideal gas constant
