A

If something is shiny

2
Q

Define Malleability

A

How flexible something is

3
Q

Define Ductility

A

If something can be coiled into a wire

4
Q

Chemical Change

A

A chemical change is when the substance/s change into an entirely different substance.

5
Q

Physical Change

A

A Physical change is when the appearance of a substance can change but the chemical configuration

6
Q

Reactivity

A

Whether a substance will react or not

7
Q

corrodibility

A

Whether a substance will decay under oxygen

8
Q

Flammability

A

Whether a substance is flammable

9
Q

Toxicity

A

Whether a substance is toxic

10
Q

Light Sensitivity

A

Whether a substance reacts to light or not

11
Q

Nuclei Decay

A

When a Radioactive substance attempts to become stable by emitting Alpha/Beeta/Gamma rays.

12
Q

Product

A

Chemical substances which result from a chemical reaction

13
Q

Reactant

A

The original substances present in a Chemical Reaction

14
Q

Reagent

A

A type of reactant

15
Q

Aqueous

A

Water related

16
Q

Precipitate

A

Solid formed when two liquids are mixed together

17
Q

Exothermic

A

Something that gives off heat and gets hot

18
Q

Endothermic

A

Something that absorbs heat and gets cold

19
Q

Nuclear Fission

A

A radioactive decay process in which the atom splits into two Nuclei causing immense bursts of Energy

20
Q

Nuclear Fusion

A

A nuclear reaction from low atomic number elements in which they form to create heavier nucleus that produces energy

21
Q

Law of Conservation of Mass

A

law that states that, in a chemical reaction, the total mass of the reactants is the same as the total mass of the products - matter can’t be created nor destroyed only transformed.

22
Q

Law of Constant Proportions

A

law that states that, in chemical compounds, the ratio of the elements is always the same

23
Q

Chemical Energy

A

Energy stored in chemical bonds that is released during chemical reactions

24
Q

Chemical Process

A

A reaction that changes the arrangement of the atoms or molecules of the substances involved

25
Q

Nitroglycerin:

A

A highly explosive liquid

26
Q

Synthesis Reactions

A

A Synthesis reaction occurs when two reactants form a larger product. It is the opposite of a Decomposition Reaction.

27
Q

Decomposition Reaction

A

A Decomposition reaction occurs when a large reactant turns into two or more smaller products.

28
Q

Combustion Reaction

A

A Combustion Reaction is a reaction which consists of organic substances. The product includes heat and Oxygen.

29
Q

Organic Substance

A

Organic substances must have Hydrogen and Carbon

30
Q

Single Displacement Reaction

A

This reaction is when one reactant in a compound is replaced by another. The displaced reactant is alone.

31
Q

Double Displacement Reaction

A

Also known as Precipitate reactions, the two reactants (liquids) turn into a solid.

32
Q

Acid-Base Reaction

A

A Acid-Base reaction must have a product of salt and water.
