Is molecular formula of a compound provides more information than its structural formula true or false?
False. The molecular formula of a compound only provides the type and number of atoms present in a molecule, while the structural formula also shows how the atoms are connected to each other. The structural formula gives more detailed information about the arrangement of atoms within the molecule.
What is the molecular formula of a compound that has a molecular mass of 54 and the empirical formula C2H3?
The empirical formula C2H3 has a molecular mass of 27 (C: 12, H: 1). To determine the molecular formula with a molecular mass of 54, the molecular formula would simply be double the empirical formula, so the molecular formula would be C4H6.
Which formula shows the numbers and types of atoms in a molecule but not the bond?
The molecular formula shows the numbers and types of atoms in a molecule but does not show the bonding arrangement between the atoms. It gives the simplest whole-number ratio of the different types of atoms in a compound.
Two compounds have the same empirical formula do theynecessairily have the same molecular formula?
No, compounds with the same empirical formula can have different molecular formulas. This is because the empirical formula gives the simplest whole-number ratio of atoms in a compound, while the molecular formula gives the actual number of each type of atom in a molecule.
What is the empirical formula for a molecule with the molecular formula of Se3O9?
To find the empirical formula, we need to simplify the subscripts in the molecular formula Se₃O₉ by dividing them by their greatest common divisor. The greatest common divisor of 3 and 9 is 3. Dividing both subscripts by 3 gives us Se₁O₃. Therefore, the empirical formula for the molecule with the molecular formula Se₃O₉ is SeO₃.
Is molecular formula of a compound provides more information than its structural formula true or false?
False. The molecular formula of a compound only provides the type and number of atoms present in a molecule, while the structural formula also shows how the atoms are connected to each other. The structural formula gives more detailed information about the arrangement of atoms within the molecule.
What does a structural formula depict that a molecular formula does not?
Structural formulas show a representation of the molecular structure, while chemical formulas do not. This is especially important when multiple compounds have the same chemical formula, but a different molecular structure.
Does a molecular formula show the types and numbers of atoms present in a molecule of a compound?
Yes, structural formulae show how the atoms in a compound are arranged. For example, CH3CH2CH2CH3 is the structural formula for butane. Unlike the displayed formula, it does not show the individual bonds that are formed.
Which modeling method only gives information about the number and identity of atoms in a molecule?
The molecular formula provides information about the number and type of atoms in a molecule. This formula gives the actual number of each type of atom in a molecule but does not provide information on the arrangement or connectivity of the atoms within the molecule.
Can you determine a compounds structural formula if you are given the molecular formula?
You might be able to do so in a few cases. If you take CH4 or O3, and know the bonds that those elements form, you'll see those can only be arranged one way. But if you take C4H10, this can be arranged in different ways. The four carbon atoms could be in a chain of four, which is known as Butane. Or you could have one central Carbon atom with all three of the others attached to it, this is called Isobutane. You don't know which you are talking about from just saying C4H10 alone.
What is the molecular formula of a compound that has a molecular mass of 54 and the empirical formula C2H3?
The empirical formula C2H3 has a molecular mass of 27 (C: 12, H: 1). To determine the molecular formula with a molecular mass of 54, the molecular formula would simply be double the empirical formula, so the molecular formula would be C4H6.
Which type of formula provides the most information about a compound?
Displayed - shows all the bonds and all the elements in the order which they occur
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.
What information is given by a structural formula that is not given by a simple formula?
A structural formulae gives many informations, out of which some are, number of bonds between two molecule, angle of bonding, etc. Which can be never expressed in a simple formulae.
What is the difference between a molecular and a structural formula?
A chemical formula that shows how atoms are arranged within a molecule or polyatomic ion and a molecular formula shows the number of the atoms that makes up the molecule.A molecular formula indicates the numbers and types of elements in one molecule of a substance. A structural formula indicates how the atoms are bonded to one another. Some examples include:water: H2O, H-O-Hcarbon dioxide: CO2, O=C=Ooxygen: O2, O=OIn a structural formula, each line represents a single covalent bond (one pair of shared electrons) between the atoms, and a double line represents a double covalent bond (two pairs of shared electrons) between the atoms.
Which formula shows the numbers and types of atoms in a molecule but not the bond?
The molecular formula shows the numbers and types of atoms in a molecule but does not show the bonding arrangement between the atoms. It gives the simplest whole-number ratio of the different types of atoms in a compound.
How are the empirical and molecular formulas for a compound. Related?
A molecular formula is identical to the empirical formula, and is based on quantity of atoms of each type in the compound.The relationship between empirical and molecular formula is that the empirical formula is the simplest formula, and the molecular can be the same as the empirical, or some multiple of it. An example might be an empirical formula of C3H8. Its molecular formula may be C3H8 , C6H16, C9H24, etc. Looking at it the other way, if the molecular formula is C6H12O6, the empirical formula would be CH2O.
