<h3>
Explanation:</h3>
- To answer the question we need to know a few things.
What are cations?
- Cations are positively charged ions that are formed when an atom of an element loses an electron(s).
What elements form cations?
- Metallic elements form cations since they react by losing electrons thus forming ions with a positive charge.
- For example, alkali metals such as sodium form cations with a charge of +1.
- In this case, sodium will form a cation with a charge of + 1, Na⁺
What are negatively charged ions?
- Negatively charged ions are known as anions.
- They are formed by non-metallic elements such as sulfur, argon, silicon, etc.
Answer: c. oxidation - gain of electrons
Explanation:
1. Synthesis reaction is a chemical reaction in which two reactants are combining to form one product.
Example:
2. Decomposition is a type of chemical reaction in which one reactant gives two or more than two products.
Example:
3. Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.
4. Dehydration reaction is defined as the reaction in which water is lost as product.
5. Hydrolysis reaction is defined as the reaction in which water is used for decomposition.
Example:
