What will happen when mercury and iodine crystals are ground together?
When mercury and iodine crystals are ground together, they react to form a red compound called mercury(II) iodide. This reaction is exothermic, releasing energy in the form of heat. It is important to handle these substances with caution, as mercury and iodine can be toxic.
What are conditions that large and small crystals will form?
large crystals (that form from volcanoes) form when lava under ground gets separated from the main lava chamber and begins slowly cooling. Smaller crystals form when either, one: Volcanoes erupt and lava cools, or two: Lava under ground gets separated from main lava chamber close to the surface and cools fairly quickly.
Are clouds a mixture or pure substance?
a cloud is a mixture of water vapor and dust(ground)
Which a halite crystal differs from a quartz crystal?
1) The covalent bonds in quartz are much stronger than the ionic bonds in halite. 2) The stronger bonds of quartz make it harder than halite. 3) You can easily scratch halite with a steel knife ,while you cannot scratch quartz.
Does sugar crystal undergo a physical change when ground?
Yes, when sugar crystals are ground into smaller pieces, it is considered a physical change since the chemical composition of the sugar remains the same. The change in the size and shape of the sugar crystals is a result of physical forces acting on the substance, rather than a chemical reaction occurring.
Where is basalt and gabbro formed?
Basalt is formed from volcanic lava flows that cool quickly on the Earth's surface, while gabbro is formed from the slow cooling of magma deep underground. Both rocks contain similar mineral compositions, with basalt having fine-grained crystals and gabbro having coarse-grained crystals.
Which Rock has relatively large mineral crystals and forms below ground from magma that cools and solidifies?
intrusive igneous
Why are crystals in basalt that formed under water smaller than those in basalt that formed on ground?
Crystals in basalt that formed underwater are smaller because they cool faster in the water, resulting in less time for the crystals to grow. On the other hand, crystals in basalt that formed on the ground have more time to grow as they cool more slowly, leading to larger crystal sizes.
Why do plastic rock and volcanic rock have big and small crystals respectively?
Plutonic rock tends to have large crystals because it solidifies deep underground, where the overlying material insulates it so that it cools slowly, allowing time for large crystals to form. Volcanic rock tends to have small crystals (or to be amorphous) because it solidifies above ground, where air and water can cool it quickly by convection. Rapid cooling does not allow time for crystals to grow large. Plastic rock I don't know about.
What are the characteristics of igneous rocks formed underground?
Usually they have larger crystals and coarser grain than those formed above ground.
Do rocks with small crytals form underground or above ground?
Rocks with small crystals form above ground, because when formed under ground the magma makes the rock cool slower causing more time for the crystals to grow. Above ground the rock cools faster, because the air isn't as hot under ground than above ground.
Which type of rock is formed above the ground by lava?
The general type is extrusive igneous rock.
How are intrusive rocks formed?
They are formed from the solidification of magma below the ground.
What is a type of rock formed when lava or magma cools?
the type of rock formed when lava or magma cools is igneous rock..
What year where crystals invented?
Crystals were not invented, they were simply found in the ground and someone gave them a name. They were different to what people would normally dig up from the ground because they were shiny.Hope that helped. that's what I think.
What rock has relatively large mineral crystals and forms below ground from magma that cools and solidifies?
The rock is called an "Intrusive Igneous Rock." Intrusive rocks have longer cooling times, allowing minerals to grow into larger crystals. Examples include granite, diorite, and gabbro.
How can you tell the difference between an igneous rock that formed above ground and one that formed below?
Igneous rocks that form below ground (intrusive) have larger crystals due to slower cooling, whereas igneous rocks that form above ground (extrusive) have smaller crystals or a glassy texture due to rapid cooling. Additionally, intrusive rocks may show visible layering or bands, while extrusive rocks typically have a more uniform appearance.
