The rock cycle is the process of converting rock between igneous, sedimentary, and metamorphic forms. ... Molten rock inside the Earth undergoes a phase change as it cools to produce solid igneous rock. The chemical changes which form the rock depend on the type of minerals present and how fast the rock cools.
Ions have a negative or positive charge because silver is metal. It is a cation (Ion with a positive charge).
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 .

Answer:
n = 1.24 moles
Explanation:
Given that,
Mass = 153 grams
Molar mass of KClO₃ = 122.55 g/mol
We need to find the number of moles.
We know that,
No. of moles = given mass/molar mass
So,
So, there are 1.24 moles in 153 g of KClO₃.
