| Base | pH of more than 7.
🗑
|
||||
| pH | scale used to classify solutions.
🗑
|

| Catalyst | substance that increases the rate of a chemical reaction.
🗑
|
||||
| Chemical change | result in the formation of one or more new substances with new chemical and physical properties
🗑
|
||||
| Chemical properties | be recognized only when substances react or do not react chemically with one another, that is, when they undergo a change in composition.
🗑
|
||||
| Compound | pure substances that are composed of two or more types of elements that are chemically combined.
🗑
|
||||
| Electrons | a negatively charged subatomic particle found outside of the nucleus of the atom.
🗑
|
||||
| Law of conservation of mass | The amount of matter does not change during a chemical reaction, only that the atoms are rearranged to form new substances. This is evidenced in a balanced chemical equation.
🗑
|
||||
| Metal | elements with similar properties found on the left side of the “staircase” on the periodic table.
🗑
|
||||
| Metalloid | elements with similar properties that create a “staircase” on the periodic table.
🗑
|
||||
| Mixture | physical combinations of two or more different substances that retain their own individual properties and are combined physically (mixed together).
🗑
|
||||
| Heterogeneous Mixture | is not uniform throughout, the component substances can be visibly distinguished.
🗑
|
||||
| Homogenous Mixture | is uniform throughout, the substances are evenly mixed and cannot be visibly distinguished

🗑
|
||||
| Periodic table | a quick reference for associating the name and symbol of an element.
🗑
|
||||
| Physical change | do not change the composition of a substance, only the physical properties
🗑
|
||||
| Physical properties | can be observed and measured without changing the kind of matter being studied.
🗑
|
||||
| Precipitate | a solid substance formed when two solutions are chemically combined.
🗑
|
||||
| Products | new substances formed in a chemical reaction and that they are located on the right side of the arrow in a chemical equation.
🗑
|
||||
| Protons | a positive subatomic particle found in the nucleus of an atom.
🗑
|
||||
| Reactants | substances broken apart or combined in a chemical reaction and that they are located on the left side of the arrow in a chemical equation.
🗑
