According to the Federal Reserve Bureau, the average cost of an annual premium for homeowners insurance is between $300 and $1,000.For most homeowners, the annual costs for a homeowners insurance policy can be estimated by dividing the value of the home by 1,000, then multiplying the result by $3.50.ccording to the Federal Reserve Bureau, the average cost of an annual premium for homeowners insurance is between $300 and $1,000.
Types of structural isomerism Chain isomerism These isomers arise because of the possibility of branching in carbon chains. For example, there are two isomers of butane, C4H10. In one of them, the carbon atoms lie in a straight chain whereas in the other the chain is branched.
1) Chemical formula. It shows the types of atoms in the molecule, and, using subscripts, it shows how many of each type of atom is present. The Chemical formula of butane is C 4 H 10. 2) The structural formula of a molecule shows the symbol for every atom, and it shows every bond.3) The condensed structure of a molecule shows the symbol of every central atom and of each ligand or set of ligands bonded to a central atom.) A benzene molecule contains six carbon atoms in a closed ring, it has 3 carbon-carbon double bonds and six hydrogen atoms. Using ChemSketch or on a sheet of paper, write the chemical formula, condensed structure, structural formula, and line structure of benzene.
