What three products are formed when chalk is put in vinegar?
When chalk (which is calcium carbonate) is placed in vinegar (which is acetic acid), it will react to produce carbon dioxide gas, water, and calcium acetate. The carbon dioxide gas is the fizzing that you see when the two substances are combined.
Are new materials formed when egg shells are mixed with vinegar?
When eggshells are mixed with vinegar, a chemical reaction occurs between the calcium carbonate in the eggshells and the acetic acid in the vinegar. This reaction results in the formation of calcium acetate, water, and carbon dioxide. So, new material is formed, called Calcium acetate, but eggshells physically mixed with vinegar, don't form any new material
What new material does vinegar bicarbonate of soda give?
Soudium acetate/Sodium ethanoate, water and carbon dioxide.
What does glue and vinegar make?

Is a chalk grinding a physical change?
It doesn't matter if something is reversible or irreversible. it will not depend if it is a chemical or physical change. A physical change is when the composition of a substance remains unaltered (the particles stay the same) and no new substance is produced. Such as when you make a paper plane out of paper, the appearance changed, the particles stayed the same, no new substance was created, and the paper remains paper. A chemical change is when the composition of a substance is altered and a new substance is produced. Such as when paper is burned, the new substance produced is the carbon and other gases from the fire, and the composition of the paper changes, slowly disappearing.It usually is unless you draw so rapidly that the heat of the friction heats the paper and causes it to smoke.
Why won't chalk write on your new blackboard does it need conditoning before use?

Which energy and material resources are used to make new paper?
gold
When you make a new material by combining two or more materials will the new material have the same prorities as the original materials or will the properties of the new material be different?
Combining two or more materials to create a new material can result in a new set of properties that are different from the original materials. The properties of the new material will depend on factors such as the composition, structure, and bonding between the original materials.
Can chalk be recycled and how?
Yes, chalk can be recycled by grinding it into a fine powder and mixing it with water to create a paste. This paste can then be molded into new chalk sticks and allowed to dry. Alternatively, chalk residue can be collected and used in other applications such as creating concrete or as a soil amendment for gardening.
