It can be - it can also be a solid - limestone.

limestone has a white streak.
Is a white solid obtained by heating magnesium a mixture an element or compound?
It is a compound.
What is rich lime?
Rich lime, often referred to as "quicklime" or "calcium oxide," is a chemical compound produced by heating limestone (calcium carbonate) in a process called calcination. It is a white, caustic, alkaline solid that reacts with water to form calcium hydroxide, or slaked lime. Rich lime is commonly used in various industries, including construction, agriculture, and environmental applications, for purposes such as soil stabilization, water treatment, and as a building material.
What color is ammonium chloride?
Ammonium chloride is colorless.Ammonium chloride, as a solid, is white in color. It is highly soluble in water and solutions of ammonium chloride is colourless. The solid form also sublimes on heating.
How can white phosphorus be made?
White phosphorus can be made by heating phosphate rock with carbon and silica in a furnace, which causes the phosphorus to vaporize and then condense into a solid form.
What is the streak of limestone?
A streak is the color of the powdered mineral left behind when the mineral is rubbed against a hard, rough surface. Limestone typically has a white streak due to its composition of calcium carbonate.
What is the white smoke during the shuttle launch?
The white smoke seen during a shuttle launch is caused by the ignition of the solid rocket boosters. It consists of exhaust gases and steam produced by the burning of solid propellant.
What is the mineral colour of limestone?
White.
What is CaCO3 at room temperature?
At room temperature (around 20°C), CaCO3 exists as a white solid known as calcium carbonate. It is insoluble in water but can react with acids to form calcium salts, carbon dioxide, and water. Calcium carbonate is commonly found in nature as limestone, chalk, and marble.
Why did the white limestone come by water?
Limestone can and does appear in shades of green, due to impurities.
If a limestone has a pure white colour where did it form?
Pure white limestone often forms in areas where the limestone has experienced very little exposure to impurities or contaminants during its formation process. This can happen in environments such as deep ocean basins, where the limestone can accumulate without being mixed with other sediments or minerals.
