No, mold growth is a biological process that involves the decomposition of organic matter by fungi. It is not a chemical change because the molecular structure of the substances involved remains the same.
Temperature can significantly impact the rate of decomposition. Higher temperatures typically increase the rate of decomposition by accelerating chemical reactions and microbial activity. Conversely, lower temperatures slow down decomposition processes by reducing the metabolic activity of organisms involved in breaking down organic matter.
A chemical reaction involving different molecules exchanging positions is called a double displacement reaction. Decomposition reactions involve a single compound breaking down into two or more simpler substances. They can occur independently of each other but may also be part of a more complex reaction scheme depending on the reactants involved.
A chemical equation provides information about the reactants involved, the products formed, and the stoichiometry of the reaction. It gives insight into the type of chemical reaction occurring (e.g., synthesis, decomposition, combustion) and the ratio of reactants and products involved in the reaction. Additionally, it follows the law of conservation of mass, meaning that the total mass of reactants must equal the total mass of products.
In landfills, organic matter undergoes decomposition through a series of complex microbial reactions. The major processes involved are hydrolysis, acidogenesis, acetogenesis, and methanogenesis. These reactions result in the production of gases like methane and carbon dioxide, as well as leachate that can contain various organic and inorganic compounds.
When ammonium chloride decomposes in an open container, white fumes of ammonia gas are observed along with the residue of solid ammonium chloride. The ammonia gas has a pungent smell, and the decomposition process is endothermic, meaning it absorbs heat from its surroundings.
The chemical processes involved in decomposition generate heat.

Other chemical changes that occur very slowly include the rusting of iron and the decomposition of organic matter in the soil. These processes can take years or even decades to fully manifest due to the slow rate of reactions involved.
The most important acid involved in chemical weathering is carbonic acid, which forms when carbon dioxide dissolves in water. Carbonic acid plays a key role in breaking down minerals in rocks, leading to their decomposition and eventual erosion.
Protons are not involved in chemical reactions.
Ammonium sulfide is a compound with the formula (NH4)2S, formed from ammonia and hydrogen sulfide, and is used in various applications such as in analytical chemistry and as a reducing agent. On the other hand, sulfite refers to the sulfite ion, SO3^2-, or compounds containing this ion, and is commonly used as a food preservative. Sulfite can also be involved in various chemical reactions as a reducing or oxidizing agent.
