Match the following:

Answer:

1. a chemical reaction in which one substance breaks up into two or more new substances:  decomposition reaction

2. a reaction in which two or more substances combine to form a new substance: synthesis reaction

3. the reaction of an acid with a base to form a salt and water: neutralization reaction.

4. chemical compound formed when the negative ions from an acid combine with the positive ions of a base: salt

5. two ionic compounds reacting in solution to form two new compounds, one of which is insoluble: double displacement reaction.

6. a reaction in which an active metal displaces a less active metal or hydrogen from a compound solution (or a nonmetal replaces a nonmetal from a compound in solution): Single replacement reaction

Explanation:

1. Decomposition is a type of chemical reaction in which one reactant gives two or more than two products.

Example: Li_2CO_3\rightarrow Li_2O+CO_2

2. Synthesis reaction is a chemical reaction in which two reactants are combining to form one product.

Example: Li_2O+CO_2\rightarrow Li_2CO_3

3 and 4. Neutralization is a chemical reaction in which an acid and a base reacts to form salt and water. Salt is formed when cations or positive ions of base combine with anions or negative ions of acid.

Here KCN is the salt formed by combination of K^+ from base and CN^- from acid.

Example:  H^++CN^-+K^++OH^-\rightarrow K^++CN^-+H_2O

5. A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

Example: 2NaOH(aq)+(NH_4)_2SO_4(aq)\rightarrow 2NH_4OH(aq)+Na_2SO_4(aq)

6. Single replacement reaction is a chemical reaction in which more reactive element displaces the less reactive element from its salt solution.

Example: Zn+2HCl\rightarrow ZnCl_2+H_2

Where do you find an elements energy levels
ahrayia [7]
You can find an element's amount of energy level by determining their place on the periodic table. An element's amount of energy levels are represented by which period/ row they are in. For example, Calcium has 4 energy levels. I know this because it is in the fourth period on the table.

Hope this helps!
