General Chemistry

________ studies the properties of and changes in matter

Matter

[TYPES OF MATTER]

______ is anything that occupies SPACE and has MASS

TRUE

TRUE OR FALSE:
Outside the earth or the planet that we live in PLASMA is the most abundant form of matter.

TRUE

TRUE OR FALSE:

In earth solid , liquid and gas are the most dominant forms of matter

• Solid

• Liquid

• Gas

Types of Matter [3]

Solid

[TYPES OF MATTER]

Have FIXED VOLUME and SHAPE

Liquid

[TYPES OF MATTER]

Have FIXED SHAPE and VARIABLE VOLUME

Gas

[TYPES OF MATTER]

Have VARIABLE SHAPE and VOLUME

Example:
1. Iron → atom

2. Halo-halo → Heterogenous mixture

3. Ferric (Fe+3) → Elements , Atom, Cation

4. Carbon dioxide (CO2) → Compound

5. Crude extracts → Heterogenous mixture

6. Phosphate (PO4 ^-3 ) → Molecule , Compound, Anion

[TYPES OF MATTER]

Types of Matter based on complexity [Diagram]

TRUE

[TYPES OF MATTER]

TRUE OR FALSE:
Atoms should be strictly SINGULAR

TRUE

[TYPES OF MATTER]

TRUE OR FALSE:

Elements can be SINGULAR or PLURAL

TRUE

[TYPES OF MATTER]

TRUE OR FALSE:

All COMPOUNDS are molecule but not all MOLECULES are compounds. For example:

• Helium (He) is a singular entity so it’s an atom and element

• Hydrogen (H2) is a molecule (plural) and element (the two atoms are of the same type)

• Sodium Chloride (NaCl) is a molecule and compound (Na and Cl are different types of atom)

neutral (unionized /uncharged)

[TYPES OF MATTER]

Uttering “atom”, element “, molecule, or “compound” often implies that a pure substance is _______

ion

[TYPES OF MATTER]

If an atom”, element “, molecule, or “compound” has a charge , the preferred word to use is ______

TRUE

[TYPES OF MATTER]

TRUE OR FALSE:

Based on the charge am ION can be positive (cation) or negative (anion)

Cation

[TYPES OF MATTER]

A positively charged ion

a. Cation

b. Anion

Anion

[TYPES OF MATTER]

A negatively charged ion

a. Cation

b. Anion

TRUE

[TYPES OF MATTER]

TRUE OR FALSE:

Mixtures can be comprised of one (homogenous) or multiple (heterogenous) compositions

Solution

[TYPES OF MATTER]

TRUE OR FALSE:

Majority of HOMOGENOUS substances are ______ since the solute and solvent are treated as one composition

Solution

[TYPES OF MATTER]

Solute + Solvent = ______

• Colloids

• Gels

• Lotions

[TYPES OF MATTER]

Some Examples of Heterogenous mixtures [3]

Plasma

[TYPES OF MATTER]

_____also called as IONIZED GAS , a gas with + or - charges

Ionized Gas

[TYPES OF MATTER]

Plasma is also called as _____

• Law of Conservation of Mass (by Lavoisier)

• Law of Definite Proportion / Constant Composition (by Proust)

• Law of Multiple Proportion (by Dalton)

[TYPES OF MATTER]
In order to separate pure substances from mixtures, the three fundamental laws of chemistry were put into place such as the _____ [3]

Law of Conservation of Mass

[FUNDAMENTAL LAWS OF CHEMISTRY]

______states that the total mass of substances present after a chemical reaction is the same as the total mass before the reaction

Law of Definite Proportion / Law of Constant Composition

[FUNDAMENTAL LAWS OF CHEMISTRY]

______states that in a given substance, the relative number and kinds of atoms are constant in a ratio of small whole numbers

Law of Multiple Proprotions

[FUNDAMENTAL LAWS OF CHEMISTRY]

______states that when substances combine to form new products (i.e to react), the mass of the elements are represented in the ratio of small whole numbers

Lavoiser

[FUNDAMENTAL LAWS OF CHEMISTRY]

States the Law of Conservation of Mass

Proust

[FUNDAMENTAL LAWS OF CHEMISTRY]

States the Law of Definite Proportion / Constant Composition

Dalton

[FUNDAMENTAL LAWS OF CHEMISTRY]

States the Law of Multiple Proportion

Change

[PROPERTIES AND CHANGES IN MATTER]

________ is a process that makes matter different from what it was, and is either visible or invisible.

• Physical Change

• Chemical Change

[PROPERTIES AND CHANGES IN MATTER]

Changes in matter can be ____ [2]

Physical Change

[PROPERTIES AND CHANGES IN MATTER]

Does not change the identity of matter

a.) Physical Change

b) Chemical Change

• Composition (e.g. whether things are mixed or separate)

• Tangible qualities like texture, viscosity, or color (e.g. smoothing with sandpaper, brushing paint on walls

• Actual physical state (solid, liquid, gas)

  • Melting (S→L)

  • Freezing (L→S)
