Describe the differences between molecular formulas and structural formulas for molecular compounds?

A molecular formula lists the numbers of the atoms of a specific element in a compound. A structural formula is a picture of how the atoms in a specific molecule are connected, with each atom represented by its chemical symbol. For example, oxygen's molecular formula is O2. Its structural formula is O-O.

Exaplin why structural formulas cannot be ionic substances?
Structural formulae are usually used to describe covalent molecular compounds. It is illogical to use structural formulae to describe ionic compounds because ionic compounds are typically lattice structures. This means that they are electrostatically fixed to one another, and what would normally be considered molecules run together as ions bond to multiple other ions. For example, NaCl would not look like: Na+-Cl- But rather- (Na+)-(Cl-)-(Na+)-(Cl-)- (etc.) (Cl-)-(Na+)-(Cl-)- (Na+)-etc (Na+)-(Cl-)-(Na+)-(Cl-)- (etc.) etc.- etc- etc- etc
Which name is used to describe the following molecular shape?
Trigonal pyramidal
What terms describe a substance that has a low melting point and poor electrical conductivity?
covalent and molecular
Do acid and base describe the same thing?
An acid and a base are very different compounds.
Describe a molecular dipole?
molecule or part of a molecule that contains both positively and negatively charged regions
What do molecular formulas and structural formulas have in common?
Molecular formulas contain no information about the arrangement of atoms. Because of this, one molecular formula can describe a number of different chemical structures. A structural formula is used to indicate not only the number of atoms, but also their arrangement in space.

Biologists use molecular clocks to try to measure?
Generally, a molecular clock is used to describe the rate of molecular change over time that tells you when two species, or taxa, have diverged.

What is the difference between a structural formula and a molecular model?
A chemical formula is the number of atoms in a substance, and is the same as a molecular formula (provided the substance is a molecule - if not, it has no molecular formula). A structural formula shows how the atoms are linked, and there are different interpretations of this: eg C3H8O2 is the chemical formula of 1,2 propan di-ol, which is the same as the chemical formula of 1,1 propan di-ol the structural formula however is CH2OHCHOHCH3 for 1,2 propan di-ol and CH(OH)2CH2CH3 for 1,1 propan di-ol. A displayed formula shows all the bonds: ........H..OH...H.............O-H...H...H ........|....|.....|..................|....|.....| ....H-C.-.C.-.C.-.H.....H-O-C.-.C.-.C.-.H ........|....|.....|..................|....|.....| ....H-O...H....H.................H...H....H 1,2 propan di-ol........1,1 propan di-ol ---------------------------------- Some chemicals, such as table salt, have no molecule. Thus, they only have chemical formula but not molecular formula. The chemical formula of table salt is NaCl. There are other salts, such as Na2SO4, MgSO4, etc. (If you hear people saying "the salt molecule has the formula of NaCl...", believe me, they do not know what they are talking about.) Some compounds exist as molecules- discrete entities, such as water. This kind of compounds have molecular formula. Water's is H2O. Structural formula? Never heard of.
