What else can I help you with?
Does insects and round worm exhibit calcium carbonate shells?
No, insects and roundworms do not have calcium carbonate shells. Insects have exoskeletons made of chitin, a tough, flexible protein. Roundworms lack a hard outer covering and have a smooth, cylindrical body shape.
What is the protective outer shell of coral animals made of?
No corals have a protective outer shell like a snail or clam, they actually have an inner skeleton, or endoskeleton. It is almost always composed of CaCO2, in English that's calcium carbonate. Snail and clam shells on the other hand are made of calcite or calcium carbonate mixed with calcium phosphate.
Why will lime mortar not set under water?
Carbon Dioxide (chemical formula CO2)
What is a calcareous shell?
A calcareous shell is a hard, protective outer covering made primarily of calcium carbonate, found in organisms such as mollusks, corals, and some types of algae. It serves to protect the organism from predators and harsh environmental conditions.
What is the role of calciferous glands in earthworm?
Calciferous glands in earthworms help to regulate the calcium carbonate levels in their body. These glands secrete calcium carbonate to aid in the formation of the earthworm's protective and hard outer cuticle. This helps in maintaining the structural integrity of the earthworm's body.
What does calcium do in peoples bones?
It makes them hard and strong, in the form of the mineral "calcium carbonate".
What colour is calcium hydrogen carbonate?
AKA Calcium Bicarbonate at least as a solid. Calcium hydrogen carbonate only exists in an aqueous form, meaning it is only around while dissolved in water. And it is colorless in water, I would bet those nifty white water spots from hard water are the same stuff
What is the material that hermatypic corals secrete to form their hard cup-like exskeleton?
Calcium carbonate
What is extracted by from water molluscs to build shells?
Molluscs extract calcium carbonate from seawater to build their shells. They secrete this mineral to form the hard outer layer that protects their soft bodies.
How is hard coral created?
By secreting calcium carbonate skeletons.
What substance makes coral hard?
Calcium carbonate
How does molasses react with calcium Oxide?
calcium oxide react with water it forms calcium hydroxide which is available in molasses . when molasses fermented started it leaves Co2 and alcohol. this CO2 react with calcium hydroxide it form calcium carbonate. it become hard material
How does calcium carbonate affect the use of glass pitchers and flower vases?
Calcium carbonate can leave a white film on glass pitchers and flower vases if hard water is used to wash them. This film can be difficult to remove and may require the use of a stronger cleaning agent to dissolve the calcium carbonate deposits. Regularly cleaning glassware with a mixture of vinegar and water can help prevent calcium carbonate buildup.
What is the name of the compounds that are responsible for the formation of white insoluble scum?
The compounds responsible for the formation of white insoluble scum are typically calcium and magnesium salts of fatty acids, known as soap scum. These salts can accumulate on surfaces in contact with soap and hard water, leading to the formation of the white residue.
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 element provides strength to the exoskeleton of clams and oysters?
The element that provides strength to the exoskeleton of clams and oysters is calcium, primarily in the form of calcium carbonate. This compound forms the hard shell that protects these mollusks from predators and environmental factors. The structure of calcium carbonate gives the shell its durability and rigidity, essential for the survival of these marine animals.
Does insects and round worm exhibit calcium carbonate shells?
No, insects and roundworms do not have calcium carbonate shells. Insects have exoskeletons made of chitin, a tough, flexible protein. Roundworms lack a hard outer covering and have a smooth, cylindrical body shape.
