[CHEMICAL REACTIONS] Type of Reactions

Proverbs 16:3

Chemistry

[CHEMICAL REACTIONS]

In general,______ discusses properties and changes in matter.

Chemical Reactions

Changes in matters

TRUE

[CHEMICAL REACTIONS]

TRUE OR FALSE:

When "change" is involved, the assumption is that a chemical reaction has taken place.

TRUE

[CHEMICAL REACTIONS]

TRUE OR FALSE:

Since the identity of the substance is not the same after a chemical reaction, it is called differently before and after a reaction.

Reactant (substrate)

[CHEMICAL REACTIONS]

Prior to the reaction, the matter is called a ______

Substrate

[CHEMICAL REACTIONS]

Reactant is also known as _______.

Product

[CHEMICAL REACTIONS]

Prior to the reaction, the matter is called a reactant (synonym: substrate) and after a reaction, it is called a _______.

$$Reactant(s) \longrightarrow Product(s)$$

[CHEMICAL REACTIONS]

A reaction generally looks like this:

Combination (Synthesis)

[Types of Reactions Based on Pattern]

A + B → AB

a. Combination/ Synthesis

b. Decomposition/ Analysis

c. Single displacement

d. Double displacement/ Metathesis

Decomposition (Analysis)

[Types of Reactions Based on Pattern]

AB → A + B

a. Combination/ Synthesis

b. Decomposition/ Analysis

c. Single displacement

d. Double displacement/ Metathesis

Single displacement

[Types of Reactions Based on Pattern]

A + BC → B + AC

a. Combination/ Synthesis

b. Decomposition/ Analysis

c. Single displacement

d. Double displacement/ Metathesis

Double displacement (Metathesis)

[Types of Reactions Based on Pattern]

AB + CD → AD + CB

a. Combination/ Synthesis

b. Decomposition/ Analysis

c. Single displacement

d. Double displacement/ Metathesis

TRUE

NOTE: When an acid and a base (two reactants) are combined, water and a salt are the two products

TRUE OR FALSE:

Neutralization is also considered as Double displacement (Metathesis)

Double displacement/ Metathesis

[Types of Reactions Based on Pattern]

Acid and base → salt + water
a. Combination/ Synthesis

b. Decomposition/ Analysis

c. Single displacement

d. Double displacement/ Metathesis

TRUE

TRUE OR FALSE:

Most redox reactions are double displacement
