Which substance shows a substance that is not molecular?
A formula unit.
What is the molecular formula of a substance that has an empirical formula of C2H5 and a molecular mass of 58 grams per mole?
The empirical formula of C2H5 corresponds to an empirical mass of 29 g/mol. To find the molecular formula from the empirical formula and molecular mass, divide the molecular mass by the empirical mass to get the "scaling factor" (58 g/mol ÷ 29 g/mol = 2). Multiply the subscripts in the empirical formula by the scaling factor to get the molecular formula: C2H5 x 2 = C4H10. So, the molecular formula is C4H10.
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.
Can any one substance have the same empirical formula and molecular formula?
Yes, a substance can have the same empirical formula and molecular formula if it consists of the simplest whole number ratio of its elements, and that ratio also represents the actual number of atoms in a molecule. This occurs in compounds like water (H₂O), where the empirical formula (H₂O) and the molecular formula (also H₂O) are identical. However, this is not the case for substances with larger molecular structures, where the empirical formula would typically represent a reduced ratio of atoms compared to the molecular formula.
Can an empirical formula be triple its molecular formula?
No, an empirical formula represents the simplest whole-number ratio of atoms in a compound, while a molecular formula shows the actual number of each type of atom in a molecule. Therefore, an empirical formula cannot be triple its molecular formula.
Which substance shows a substance that is not molecular?
A formula unit.
What is the that shows the no. of atoms and it's kind in a substance?
The molecular formula provides these information .
Which formula show a substance that is not molecular?
A formula unit.
Can you determine the molecular formula of a substance from its percent composition?
Not completely. The empirical formula of a substance can be determined from its percent composition, but a determination of molecular weight is needed to decide which multiple of the empirical formula represents the molecular formula.
Can one substance have same empirical and molecular formula?
Yes, it is possible for a substance to have the same empirical and molecular formula. This can occur when the substance is composed of only one type of element, such as oxygen gas (O2), where both the empirical and molecular formula are O2.
Which chemical formula is both an empirical formula and a molecular formula?
Water (H2O) is a chemical formula that is both an empirical formula and a molecular formula. The empirical formula shows the simplest whole-number ratio of atoms in a compound, while the molecular formula shows the actual number of each type of atom in a molecule.
Is CH2O an empirical or molecular formula?
CH2O is both the empirical and molecular formula for formaldehyde. The empirical formula shows the simplest whole-number ratio of atoms, while the molecular formula shows the actual number of each type of atom in a molecule.
What formula represents a substance that contains covalent bonds?
A molecular formula represents a substance that contains covalent bonds. This formula shows the types and numbers of atoms present in a molecule, such as H2O for water, which consists of covalent bonds between hydrogen and oxygen atoms.
Which formula shows a substance that is not molecular h2 h h2o co2?
CO2 is not a molecular substance, as it is composed of one carbon atom and two oxygen atoms forming a covalent bond. The molecular formulas for H2, H, and H2O represent molecular substances where atoms are bonded together by sharing electrons.
What is the molecular formula of silver?
Ag is the molecular formula for silver. If you look on a periodic table, you will find this substance with the transitional metals and with the atomic number of 47.
C2H2 is a chemical formula for acetylene. Which type of chemical formula is this A molecular formula An empirical formula A structural formula?
C2H2 is a molecular formula because it shows the actual number of atoms of each element present in a molecule of acetylene.
What is identity of a substance?
The identity of a substance (chemical compound) is defined by his chemical formula and molecular structure.
