CHEMICAL EQUATION

Question 1

Process in which one or more substances are changed into new substance with different physical and chemical properties

Answer 1

Chemical Equation

Question 2

Follow the law of conservation of mass (No atoms are created or destroyed; they are just rearranged)

Answer 2

Chemical Equation

Question 3

Energy in the form of heat is added to the reaction

Answer 3

triangle

Question 4

Represents the gaseous product of a chemical reaction

Answer 4

Arrow

Question 5

Types of Chemical Reactions

Answer 5

1. Combination or Synthesis
2. Decomposition
3. Single Displacement
4. Double Displacement
5. Combustion

Question 6

Involves two or more elements or compounds reacting to form a bigger compound (product/s)

Answer 6

Combination or Synthesis

(A + B = AB)

Question 7

A single compound as a reactant is broken down into two or more simpler substances (can either be elements or compounds)

Answer 7

Decomposition

(AB = A + B)

Question 8

One element replaces another in an ionic compound; a metal can replace the cation in the compound while nonmetals can replace the anion component

Answer 8

Single Displacement

(A + BC = AC + B)

Question 9

Two ionic compounds exchange ions

Answer 9

Double Displacement

(AB + CD = AD + CB)

Question 10

Special type of reaction; a hydrocarbon (compound containing carbon and hydrogen atoms only, in some cases with oxygen) reacts with oxygen to form carbon dioxide and water

Answer 10

Combustion
