A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Chemical reactions can be either spontaneous, requiring no input of energy, or non-spontaneous, typically following the input of some type of energy, such as heat, light or electricity. Chemical reactions are usually characterized by a chemical change, and they yield one or more products after the reaction is complete. Chemical reactions are described with chemical equations, which symbolically present the starting materials, end products, and sometimes intermediate products and reaction conditions. Chemical reactions happen at a characteristic reaction rate at a given temperature and chemical concentration. Typically, reaction rates increase with increasing temperature because there is more thermal energy available to reach the activation energy necessary for breaking bonds between atoms.

In chemistry, a combination reaction is a chemical reaction in which two or more reactants combine to form more than one product. In a decomposition reaction, one reactant splits into two or more products.

We have given information, there are 3 carbon atoms, 5 florine atoms, 2 hydrogen atoms and 1 chlorine atom. Therefore, the molecular formula fhermolam of isoflowrine isophlorine is c 3, a 5 o eh 5 c l and we have to find the percent composition by masso. The molar mass of isa. Florine is molar mass of isoclorineis equal to 3 into molar mass of carbon plus 5 into molar mass of chlorine plus molar mass of oxygen plus 2 into molar. Mass of hydrogen plus modal mass of chlorine is equal to 3 into molar. Mass of carbon is 12.011 gram per mole plus 5 into molar. Mass of florine is 18.998 gram per mole, plus smaller mass of oxygen is 15 molar. Mass of oxygen is 15.999 gram per mole plus 2 into molar. Mass of hydrogen is 1.008 gram per mole, plus molar mass of chlorine is 35.453. Gram per mole is equal to 184.491 gram per mole. Now we can find the mass percent composition, so mass percent of carbon in a compound is equal to 3 into molar mass of carbon divided by molar. Mass of the compound is puran. Isori is c, 3 c 35, o h, 2 c. L into 100 percent is equal to 3 into molar. Mass of carbon is 12.011 gram per mole. Divided by molar, mass of isaflorine is 1 hude 84.491 gram per mole is equal to the calculated percent of carbon. Is 19.53 percent per mole cancel with gram per mole and the value is 19.53 percent and percent of florine in a compound? Is equal to mass of florine divided by a molar mass of chlorine divided by molar mass of isolorine c, 3, f, 5, o h, 2 c. L i to 100 percent, is equal to molar mass of florins 18.998 gram per mole divided by molar. Mass of isoclorine is 184.491 gram per mole into 100 percent is equal to 10.30 percent. The mass percent of florine in a compound here, gram per mole, can cell with gram per mole and the next is percent by mass of oxygen in a compound is equal to molar mass of oxygen divided by molar mass of isophluorine c, 3. F: 5 o h, 2 c l into 100 percent is equal to molar. Mass of oxygen is 15.999 gram per mole. Divided by molar, mass of isoclorine is 184.491 gram per mole into 100 percent is equal to. We have 8.67 percent by mass of oxygen in a compound and percent of hydrogen in a compound is equal to molar mass of 2 into molar mass of hydrogen divided by molar mass of isoline, a 5 o h, 2 c. L into 100 percent is equal to 2 into molar. Mass of hydrogen is 1.008 gram per mole. Divided by molar, mass of isocluorine is onered 84.491 into 100 percent is equal to 1.09 percent of hydrogen present in a compound and present composition of chlorine in a compound is equal to percent of chlorine is equal to molar mass of chlorine divided by molar mass of Hypochlorine c 3, f, 5, o h, 2 c l into 100 percent is equal to the molar. Mass of chlorine is 35.453 gram per mole. Divided by 184.491 gram per mole into 100 percent is equal to. We have 19.22 percent by mass of chlorine in a compound. So here, gram per mole is canceled with gram per mole, and here is also gram per mole. Cancel with gram per mole and the final result is the molecular formula is ormula is c 3 a 5 o h, 2 c l, the persent composition by mass by mass carbon percent composition by mass of carbon is 19.53 percent. Florine is 10.30 percent. Oxygen is 8.67 percent, hydrogen is 1.09 percent in chlorine is 19.22 percent.
