Alum is the least soluble until the temperature of the water increases to about 65 °C.

<h3>What is an alum?</h3>

Alum is any of a group of hydrated double salts, usually consisting of aluminium sulfate, the water of hydration, and the sulfate of another element.

The first test is to find the melting temperature of the compound and compare this value with the accepted (published) value for alum (92.5°C).

The second test determines the water of hydration present in the alum crystals.

The third test is a chemical test to determine the per cent sulfate in your sample of alum.

Hence, alum is the least soluble until the temperature of the water increases to about 65 °C. After that point, the solubility of alum is greater than that of salt but never as great as sugar.

Which molecule is usually comprised of six carbons in a ring (with six sides)?
Oksana_A [137]
The hydrocarbon is usually named using the prefix that would indicate or entail how many carbon are present in it. For six carbons, the name would begin with hexa-. For cyclic molecule, the name would begin further with cyclo-. Thus, for the molecule that is described above, the name would be, cyclohexane. 

Another, more well-known, component is the cyclic molecule with alternating double bonds, this will be named, benzene.

Scientists use the theory of plate tectonics to understand the reasons volcanoes develop in
Firdavs [7]

Scientists use tectonics plates to understand the plates moving beneath the volcano.

<h3>What are tectonic plates?</h3>

According to the widely recognized scientific hypothesis known as plate tectonics, the Earth's lithosphere is made up of many sizable tectonic plates that have been steadily moving for nearly 3.4 billion years. Our globe would look drastically different if it weren't for plate tectonics. We have a stable climate, mineral and oil deposits, and oceans with a chemical balance that supports life thanks to the continuous recycling of the Earth's crust. Even now, every few hundred million years, it offers evolution a boost. The plates fit tightly against one another and sit on the heated, molten rock of the Earth's mantle like fragments of a broken shell. The plates move as a result of the heat produced by nuclear processes occurring inside the planet.
