What is the reddish-brown Substance in the water?

Key Concepts

apariciocortesaldo — 2024-11-15 18:39:49 UTC

Different Substances have different Properties.
Things that are too small (or too large) to see can be studied with models.
Substances have different properties because they are made of different groups of atoms. These groups vary in the type or number of atoms they make up the group.
Groups of atoms repeat to make up a substance.

Property: Something that can be observed about a substance, such as color, smell, or boiling point.

Melting point: the temperature at which a substance changes from the solid phase to the liquid phase

Boiling point: the temperature at which a substance changes from the liquid phase to the gas phase.

Atoms: the tiny pieces that all matter-all the stuff in the world-is made of.

Scale: the relative size of things.

Substance: something that is made of all the same atoms of groups atoms.

Element: a substance that cannot be broken down into simpler substance.

Extended structure: a structure formed by repeating groups of atoms liked together.

Repeating atom group: a group of atoms that is repeated within a molecule.

The claim I chose..

apariciocortesaldo — 2024-11-25 19:45:47 UTC

I say claim 2: Two samples have the same properties. Therefore they are the same substance. However, one sample has a different set of properties. Therefore, this sample is a different substance.

chapter 2 question

apariciocortesaldo — 2024-12-02 19:59:52 UTC

How did the rust form?

I say it came from the rust of the pipe and the rust from the fertilizer.

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

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

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

Vocabulary

Chemical reaction: a process in which atoms rearrange to form new substance.

reactant: a starting substance that is part of a chemical reaction.

Product: an ending substance that is made during a chemical reaction.

Rearrange: to change the order or position of something.

what claim I chose

I chose claim 3: the iron pipes and the fertilizer change into rust.

chapter 3 question

apariciocortesaldo — 2024-12-09 19:42:23 UTC

what happened to the atoms of the substance during the chemical reaction.

Key concepts

apariciocortesaldo — 2024-12-09 19:44:20 UTC

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

During a chemical reaction, atoms cannot be created or destroyed.
