Large minerals are created from magma, when magma rises to the Earth's surface it cools slowly. As the magma cools, solid rocks form. Rocks are mixtures of minerals. Granite is a common rock that forms when magma cools. It contains the minerals quartz, plagioclase feldspar, and potassium feldspar. The different colored speckles in the granite are the crystals of the different minerals. The mineral crystals are large enough to see because the magma cools slowly, which gives the crystals time to grow.
Small minerals are created from lava, since lava is on the Earth's surface so it cools quickly compared to magma on Earth. Hence, rocks form quickly and mineral crystals are very small. Sometimes, lava cools so hastily that crystals cannot form at all, forming a black glass called obsidian. Because obsidian is not crystalline, it is not a mineral.
NOTE: Minerals (and gems) are crystals.
Answer:
<u>49.54 g</u>
Explanation:
Let's take the masses of both calcium sulfate and sulfur dioxide formed.
Sulfur dioxide = 32 + 2(16) = <u>64 g</u>
Calcium sulfate = 40 + 32 + 4(16) = <u>136 g</u>
So, under ideal conditions, to produce 136 g of Calcium sulfate, we require 64 g of Sulfur dioxide.
But, it mentions the process is only 95% efficient.
Hence, taking the ratio :
x = <u>49.54 g</u> (approximately)
Explanation:
Over the next 60 seconds, the water in the beaker will try to attain thermal equilibrium by bringing the temperature in both beaker to the same level.
- Heat generally moves over a gradient from a place of higher temperature to one with lower temperature.
- The copper rod is a metallic conductor.
- Heat will flow from the beaker at 85°C to the beaker at 15°C
- During the passage of time, the liquids in both beaker will reach thermal equilibrium and the temperature will be the same.
Potential energy is stored energy that has not been used yet. kinetic energy is energy that is being used instead of being stored. batteries have stored energy that is not being used until the battery is put into a device that can convert the energy that is stored into energy that is used. in example, putting batteries into a remote puts the stored energy into use by powering the remote.
