What else can I help you with?
Why do you use both empirical and molecular formula?
Molecular formulas are used the most often, but empirical formulas do help at times. Often it's just to simplify the molecular formula, but this simplification can often tell you if it's in the same chemical family as other compounds and such.
What is the term for numbers that appear in the chemical formulas of some compounds coefficients subscripts exponents square roots?
The term for numbers that appear in the chemical formulas of compounds is "subscripts." Subscripts indicate the number of atoms of each element in a molecule. Coefficients, on the other hand, refer to the numbers placed in front of compounds in a chemical equation to indicate the number of molecules involved.
Is formulae used to describe molecules or to name compounds?
A chemical formula would describe a molecule by its constituent parts. The chemical name, however, also is based on chemical formula, and will also describe the molecule.
How are the empirical and molecular formulas for a compuond related?
An empirical formula is a brutto formula; a molecular formula explain the structure of a molecule.
How do the pictures compare to the chemical formulas?
Pictures visually represent the structure of molecules, showing the arrangement of atoms and bonds. Chemical formulas provide a symbolic representation of the elements and the number of atoms in a molecule. Pictures offer a more intuitive understanding of the molecular structure, while chemical formulas offer a concise and standardized way to represent the composition of a compound.
What are formulas for a covalent compounds called?
Formulas for covalent compounds are called molecular formulas. They show the types and numbers of atoms in a molecule.
How do pictures of elements and compounds compare to chemical formulas?
Pictures of elements and compounds provide a visual representation of their structure and arrangement of atoms, whereas chemical formulas use symbols and subscripts to denote the types and numbers of atoms in a molecule. Pictures can offer a more intuitive understanding of the molecular structure, while chemical formulas provide a concise and standardized way to represent compounds. Both are important for understanding the properties and behavior of substances in chemistry.
What is the relationship between bond polarity and molecular polarity in chemical compounds?
The relationship between bond polarity and molecular polarity in chemical compounds is that the overall polarity of a molecule is determined by the polarity of its individual bonds. If a molecule has polar bonds that are not symmetrical, the molecule will be polar overall. Conversely, if a molecule has nonpolar bonds or symmetrical polar bonds that cancel each other out, the molecule will be nonpolar.
Why do chemists use structural formulas for organic compounds rather then molecular formulas such as C5H12?
Starting with C4H10, hydrocarbons can have multiple configurations, called isomers, for the same formula. These isomers are regarded as different compounds and have different physical and chemical properties. In such cases simply using the chemical formula would be ambiguous.
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.
What is the significance of the cyanide molecular orbital diagram in understanding the chemical properties of cyanide compounds?
The cyanide molecular orbital diagram is important in understanding the chemical properties of cyanide compounds because it shows how the electrons are arranged in the molecule. This arrangement affects how cyanide compounds interact with other substances, influencing their reactivity and behavior in chemical reactions.
What is the name for a molecule that has a different arrangement of atoms?
When the same elements form compounds with different molecular forms, the compounds are known as isomers. (They may have different chemical properties.)
What is true about molecular compounds?
Molecular compounds are formed by sharing electrons between atoms, leading to the formation of covalent bonds. They do not conduct electricity in their solid form because they do not contain free ions. Molecular compounds typically have lower melting and boiling points compared to ionic compounds.
Why ionic compounds do not posses molecular formula?
it is not a molecule
When are structural formulas used?
Structural formulas are used primarily for organic compounds for which molecular formulas correspond to more than one isomer, or for chemical discussions in which the shapes of molecules are important, such as crystallography.
