Chalk is composed of calcite which is calcium carbonate. When CaCO3 is heated the carbon dioxide from its structure escapes thus breaking its well formed structure which breaks and the chalk crumbles.
Chalk is calcium carbonate, a salt, but it is mildly basic.
Camphor can be separated from chalk powder using sublimation. Heating the mixture will cause the camphor to sublime (convert directly from solid to gas) and leave behind the chalk powder. The camphor gas can then be collected and allowed to solidify back into crystals.
No, melting chalk is impossible, but dissolving chalk is possible. This can be done when you mix the chalk with some liquid and there you have it...DISSOLVED CHALK IN A LIQUID!
No, sulfur and chalk are not the same thing. Sulfur is a chemical element known for its distinct yellow color and strong smell, while chalk is a soft, white sedimentary rock composed mainly of calcium carbonate. They have different physical and chemical properties.
Chalk is composed mainly of calcium carbonate, which is an ionic compound. Calcium carbonate consists of calcium ions (Ca^2+) and carbonate ions (CO3^2-), which are held together by ionic bonds. These strong electrostatic attractions between the ions make chalk an ionic compound.
Depending on what you mean by strong, chalk is terribly weak in terms of erosion.
Chalk is not soluble in cold water. It is primarily composed of calcium carbonate, which is only slightly soluble in water. Warm or hot water may slightly increase the solubility of chalk but it will not fully dissolve.
Chalk is calcium carbonate, a salt, but it is mildly basic.
When chalk is submerged in water for more than a week, it may start to disintegrate and break apart due to the exposure to moisture. The water will gradually dissolve the calcium carbonate in the chalk, causing it to lose its integrity and crumble over time.
Chalk is primarily affected by physical weathering processes like freeze-thaw cycles and abrasion by wind or water. Chemical weathering can also occur, particularly from exposure to acidic rain or groundwater which can dissolve the calcium carbonate in chalk. Over time, these processes can cause chalk to erode and crumble.
chalk is made from a chalk like rock. The reson why its hard is because it a rock and the reson why it break so easy is because of its weight and size

Chalk is made of calcium carbonate, which is slightly soluble in water due to its ionization into calcium and carbonate ions. When chalk is exposed to tap water, the water molecules break down the chemical bonds in the chalk, causing it to dissolve and form a solution.
