Answer: check for a change in total mass during a reaction.
According to the law of conservation of mass during a chemical change the total mass of the products remains equal to the total mass of the reactants: there is not change in the total mass.
During nuclear reactions the mass can change due to the huge release of energy which proceeds from mass change, as per the famous equation ΔE =Δm. c^2.
Amide is produced when a 2° amine and an acid chloride combine.
Acid chloride: What is it?
- The chemical name for acid chloride is RCOCl, where "R" stands for a side chain. They are reactive derivatives of carboxylic acids. In organic chemistry, an acyl group and a chlorine atom form an organic molecule known as an acyl chloride (also known as acid chloride).
- A functional group identified by the RCO molecular formula is called an acyl group. Since acyl chlorides are often hazardous, handling them requires extra care.
- They have the potential to produce HCl and organic compounds when they interact with water on the surface of the eye, irritating the eye. Anhydrous acid salts are neutral because it lacks an H+ donor.

Answer:
Limestone caves are formed when acid rain occurs.
Explanation:
When chalk pieces which is made of calcium carbonate react with acetic acid, it produces carbon dioxide, calcium acetate, and water. When calcium carbonate react with Carbonated Water produces calcium bicarbonate. Limestone cave forms when the dissolution of limestone occur when rainwater which is acidic due to the addition of carbondioxide in the air react with limestone. This dissolution removes the lime from the rock and caves are formed.
