How do new substances form ?

Chapter 1 Question

elnathannolan — 2024-11-15 14:49:22 UTC

What is the reddish brown substances in the water.

Key concept 1

elnathannolan — 2024-11-15 14:50:06 UTC

Different substances have different properties.

Key Concepts 2

elnathannolan — 2024-11-15 14:51:19 UTC

Things that are too small ( or too large) to see can be studied with models.

Key Concept 3

elnathannolan — 2024-11-15 14:53:34 UTC

Substances have different properties because they are made of different groups of atoms. These groups vary in the type or number of atoms that make up the group.

Key Concept 4

elnathannolan — 2024-11-15 14:54:29 UTC

Groups of atoms repeat to make up a substance.

Property

elnathannolan — 2024-11-15 14:57:22 UTC

Something that observed about a substance, such as color, smell, or boiling point.

Substance

elnathannolan — 2024-11-15 14:58:23 UTC

Something that can is made of all the same atoms and groups of atoms.

Melting Point

elnathannolan — 2024-11-15 14:59:38 UTC

The temperature at which a substance changes from the solid phase to the liquid phase.

Boiling Point

elnathannolan — 2024-11-15 15:00:35 UTC

The temperature at which a substance changes from the liquid phase to the gas phase.

Atoms

elnathannolan — 2024-11-19 15:00:38 UTC

The tiny pieces that all matter- all the stuff in the world- is made of

Scale

elnathannolan — 2024-11-22 14:56:15 UTC

The relative size of things

Extended Structure

elnathannolan — 2024-11-22 14:58:04 UTC

A structure formed by repeating groups of atoms linked together in a large network.

Chapter 2 Question

elnathannolan — 2024-12-03 14:57:00 UTC

How did the rust form ?

Key Concept 5

elnathannolan — 2024-12-12 15:01:17 UTC

During a chemical reaction, one or more starting substances(reactants) change into one or more different substances.

Key Concept 6

elnathannolan — 2024-12-13 14:54:14 UTC

During a chemical reaction, atoms do not change from one type to another.

Key Concept 7

elnathannolan — 2024-12-13 14:55:11 UTC

During a chemical reaction, atoms rearrange to form different groups of atoms.

Chapter 3 Question

elnathannolan — 2024-12-13 14:56:51 UTC

What was the produced during the reaction between the iron pipes and the fertilizer.

Key Concept 8

2024-12-17 14:57:01 UTC

During a chemical reaction, all of the atoms that make up the reactants rearrange to form the products.

Key Concept 9

elnathannolan — 2024-12-17 14:58:06 UTC

During a chemical reaction atoms cannot be created or destroyed.
