Why do Minerals in geodes form spectacular euhedral crystals?
Minerals in geodes form spectacular euhedral crystals because they have space to grow freely without environmental constraints, leading to well-defined crystal faces. The slow cooling and precipitation of dissolved minerals inside the geode also contribute to the formation of large, well-formed crystals.
Does silicon form compounds made of long chains of atoms?
Yes, silicon can form compounds with long chains of atoms called polysilicones or silicones. These compounds are known for their flexibility, thermal stability, and water repellent properties. Silicon-oxygen chains can also form in silicates, which are common minerals in the Earth's crust.
Salt and vinegar crystals?
they are the cristals which form when vinegar is left for a long time.
How long does it take for crystals to form when water evaporates?
This depends on many factors.
Why is it that some igneous rock is made of large crystals and some is made of small crystals?
An igneous rock's crystal size is dependent on how long it takes to cool from magma into a solid. Intrusive igneous rocks, the ones that solidify from magma underground, are slow to harden, giving crystals plenty of time to grow larger. Extrusive igneous rocks, formed from lava above ground, cool fairly rapidly, not allowing the crystals much time to grow in size.
What below the Earths's surface cools and hardens to form mineral crystals?
Magma beneath the Earth's surface cools and solidifies to form mineral crystals. This process takes place over long periods of time, allowing different types of crystals to form depending on the minerals present in the magma.
How long does it take for salt crystals to form?
The time it takes for salt crystals to form can vary depending on factors like temperature and concentration of the salt solution. Typically, it can take a few hours to a few days for visible salt crystals to form.
Why should large crystals of sodium chloride be used instead of small crystals?
Large crystals of sodium chloride are preferable for certain applications because they have a lower surface area compared to small crystals. This can reduce the rate of reactions or dissolution, making them suitable for slow-release or long-term applications. Additionally, large crystals may be easier to handle and manipulate in certain industrial processes.
What affects the size of crystals formed from magma?
The rate at which the magma cools affects the size of the crystals that form. If it cools slowly, large crystals will form. If it cools rapidly, small crystals will form.if it takes the rock a long time to cool down the crystals will be bigger if the rock takes a short time to cool the crystals will be smaller
What determines the size of crystals that form in granite?
The cooling rate of magma plays a significant role in determining the size of crystals.
What is the appearance of pure sulfanilamide after crystalization?
snowy white needle looking , long crystals
How long do crystals from crystal making kits take to form?
It takes about two to four weeks
