The empirical formula of a chemical compound represents the ratio of the elements present in that compound.

Kevlar chemical formula equation. Fig 1 - Kevlar molecule structure diagram. H 2 O 2 H 2 O Na 2 Cl 2 NaCl. -Percent Composition by mass is 172 Carbon123 Hydrogen25 for Nitrogen and Oxygen-The density of kevlar when spun has a density of around 144.

For instance equation C6H5C2H5 O2 C6H5OH CO2 H2O will not be balanced but PhC2H5. Empirical formulae are usually obtained based on the analysis of experimental data. Kevlar trademarked name of poly-para-phenylene terephthalamide a nylonlike polymer first produced by Du Pont in 1971.

27082018 At the heart of chemistry are substances elements or compounds which have a definite composition which is expressed by a chemical formulaIn this unit you will learn how to write and interpret chemical formulas both in terms of moles and masses and to go in the reverse direction in which we use experimental information about the composition of a compound to work out a formula. There are two oxygens on the left but three on the right. Substitute immutable groups in chemical compounds to avoid ambiguity.

Nylon-66 is made by polymerising hexanedioic acid and 16-diaminohexane exactly as shown further up the page. In a chemical reaction one or more reactants are transformed into products. 15052011 Kevlar poly-phenyleneterephtalamide The Chemical Formula of Kevlar is C14H10N2O2.

-Molar mass is 9785688 gmol. Carbons 1 and 4. The balanced equation will appear above.

Ionic charges are not yet supported and will be ignored. It is an organic compound. There are eight hydrogens on the left but only two on the right.

Enter a chemical equation to balance Chemical Equations Examples. The empirical formula for glucose is CH 2 O. For example the reaction of mercury with oxygen to produce mercuric oxide would be expressed by the equation.

Balancing chemical equations isnt. Fe Au Co Br C O N F. Balanced Equation- C3H8 5O2 ---.

Kevlar can be made into strong tough stiff high-melting fibres five times stronger per weight than steel. Kevlars scientific name is poly-phenylene terephthalamide as it is formed by the synthesis of 14 phenylene-diamene and terephthaloyl chloride which yields hydrochloric acid as byproduct. Example 1 Unbalanced Equation- C3H8 O2 ---.

If you line these up and remove water between the -COOH and -NH 2 groups in the same way as we did with nylon-66 you get the structure of Kevlar. It is used in radial tires heat- or flame-resistant fabrics bulletproof clothing and fibre-reinforced composite. Kevlar is a polyamide a type of synthetic polymer in which the amide groups are separated by para phenylene groups meaning that the amide groups are attached to each other on opposite sides of the phenyl group ie.

Use uppercase for the first character in the element and lowercase for the second character. To balance a chemical equation enter an equation of a chemical reaction and press the Balance button. H2O CO2 There are three carbons on the left but only one on the right.
