Naming Of Compounds Flashcards
What is the name for FeSO4 .7H2O?
Iron(ll) tetraoxosulphate(VI) heptahydrate
What is the name for Na2CO3 . 10H2O?
Sodium trioxocarbonate (IV) decahydrate
How are double salts named?
All cations are named first in alphabetical order, except hydrogen is placed last, then all anions in alphabetical order
What is the name for AlNH4 (SO4)2*12H2O?
Aluminium ammonium bis tetraoxosulphate (VI) deodecahydrate
How are basic salts named?
All cations are named first in alphabetical order, followed by all anions also in alphabetical order
What are acid salts?
Salts containing replaceable hydrogen atom(s) due to incomplete neutralization of a polyprotic acid
What is the molecular formula?
A formula that shows the actual whole number of different atoms present in a molecule of the compound
What is empirical formula?
A formula that shows the simplest whole number ratio of different atoms in one molecule of a compound
What is quantitative analysis?
An analysis that determines the mass, especially the percentage by mass of the different elements present in a compound
What is the structural formula?
A formula that shows how atoms in a molecule or units are bonded to each other
What is the dashed structural formula or displayed formula?
A type of structural formula where the atoms and bonds are explicitly shown
What is the condensed structural formula?
A type of structural formula where atoms are written down in a list-like format
What is the skeletal structural formula used for?
It is normally used for hydrocarbons and represents atoms as line segments
What is the molecular formula of a compound with C6H14 as its molecular formula?
The empirical formula of C3H7
What is the purpose of qualitative analysis?
To determine the different types of elements, ions, or functional groups present in a compound/species
What is a combination or synthesis reaction?
A combination or synthesis reaction is a reaction between two or more substances to produce just one product.
Give an example of a synthesis reaction.
Fe(s) + S(s) → FeS(s) and 2N2 + 3H2 → 2NH3
Define decomposition reaction.
A decomposition reaction is a reaction in which one reactant breaks down to give two or more simpler products, often under the effect of heat.
What are the three ways decomposition reactions may be caused?
Decomposition may be caused by heat (thermal decomposition), by light (photo decomposition), or by electrolysis (electrolytic decomposition).
Give an example of a thermal decomposition reaction.
MgCO3(s) → MgO(s) + CO2(g)
What is double decomposition?
Double decomposition is a reaction in which two compounds react to form two new compounds by an exchange of ions.
What is a precipitation reaction?
A precipitation reaction is a reaction between two solutions to form an insoluble product.
Give an example of a precipitation reaction.
Pb(NO3)2(aq) + 2NaCl(aq) → PbCl2(s) + 2NaNO3(aq)
What is a neutralization reaction?
A neutralization reaction is a reaction between an acid and a base to produce water and a salt.
