What is non-spontaneous reaction?

A nonspontaneous reactio is one that doesn’t favor the formation products under the specified conditions. Nonspontaneous reactions must be either endothermic or accompanied by a decrease of entropy. Our atmosphere is primarily composed of a mixture nitrogen and oxygen gases.

Is dissolving sugar in coffee spontaneous?

The dissolution of sugar in hot coffee is a spontaneous process.

Is sugar dissolving in hot coffee a chemical change?

The dissolution of sugar in water is one example of a physical alteration. Here’s the reason: Chemical changes produce new chemical products. To make sugar in water a chemical modification, something must happen. However, mixing sugar and water simply produces…

Is tarnishing a chemical reaction?

Tarnish results from a chemical reaction between a metallic and non-metal compound, such as oxygen or sulfur dioxide. It is often a metal oxide. This is the result of oxidation. Sometimes, the metal oxide reacts with water to form the hydroxide. Carbon dioxide is used to make carbonate. It is a chemical reaction.

Is Limestone a chemical reaction?

Heating limestone causes a chemical reaction. The limestone becomes lime and carbon dioxide. Each formula is represented by a symbol that indicates the physical state of the substance.

What happens when limestone reacts with dilute HCl?

A piece of limestone reacts to dilute HCl to produce a gas X. A white precipitate Y forms when gas X passes through lime water. The white precipitate is formed when excess gas X is passed through lime water. It then dissolves and forms a soluble compound Z. (i) limestone reacts with dilute HCl.

Which gas is formed when cac2 is allowed to react with dilute HCl?
