- 1What Is a Triad?A group of three elements with similar chemical properties in which the atomic weight of the middle element is approx equal to the average of the other two
- 2What is an atomic number?An atomic number is the number of protons in the nucleus of an atom
- 3What is an atomic mass number?An atomic number is the number of neutrons and protons in the nucleus of an atom
- 4What is an ion?An Ion is an atom that has either lost or gained electrons.
- 5What is 'The Law Of Conservation Of Mass'?The Law Of Conservation Of Mass states that the total mass of products of a chemical reaction is the same as the total mass of reactions
- 6What is 'The Law Of Conservation Of Matter'?The Law Of Conservation Of Mass states that in any chemical reaction, matter is neither created nor destroyed but merely changes form
- 7Acid + Metal equals?Salt & Hydrogen
- 8Acid + Base equals?Salt + Water
- 9Acid + Carbonate equals?Salt water + Carbon dioxide
- 10Most bases are?Metals, Metal oxides, Metal Hydroxides and Amonia
- 11What is Arrhenius's theory of Acid?Arrhenius's theory of Acid is that an acid is a substance that fully dissociates in water.
- 12According to Arrhenius's theory, what is a strong acid?A strong acid is one which dissociates fully in water
- 13What is Arrhenius's theory of bases?Arrhenius's theory of bases is that a base is a substance that dissociates in water to produce OH- ions
- 14According to Arrhenius's theory, what is a strong base?A strong base is one which dissociates fully in water eg. NaOH
- 15According to Arrhenius what do acids give off in solutions?Arrhenius thought that an acid gives off H+ ions in solution
- 16What are H+ ions?H+ ions are protons,
- 17What can H+ ions not do?H+ ions can't exist independently
- 18What happens when H+ ions react with water?When the acid dissociates, the H+ ions react with water molecules
- 19When the acid dissociates, the H+ ions react with water molecules, what is the chemical formula of this occurance?H+ + H20 ---> H30+
- 20What is H30 ion called?H30 is called the hydronium ion
- 21What is a limit to Arrhenius theory?A limit to Arrhenius's theory is that acids and bases are defined by reactions in water.
- 22What is Bronsted-Lowry theory on acids?Bronsted-Lowry theory on acids describes acids as substance that donates a proton
- 23What is Bronsted-Lowry theory on bases?Bronsted-Lowry theory on bases describes bases as substance that a accepts a proton
- 24What is a Conjugate Pair?Conjugate Pairs are acids and bases that exist in pairs.
- 25What defines a Conjugate Pair?A Conjugate Pair is when an acid donates/loses a proton and becomes a conjugate base and vice versa with bases
