How many grams of bromine are produced when 23.55 g of potassium bromide are consumed?
F2 + 2KBr → 2KF + Br2

15.8 g

Explanation:

In every stoichiometry problem, we must first note the equation of the reaction as it serves as a guide in solving the problem.

F2 + 2KBr → 2KF + Br2

No of moles of potassium bromide corresponding to 23.55g = mass/ molar mass

Molar mass of potassium bromide= 119.002 g/mol

No of moles = 23.55g / 119.002 g/mol

No of moles = 0.1979 moles

From the reaction equation;

If 2 moles of potassium bromide yields 1 mole of bromine

0.1979 moles of potassium bromide will yield 0.1979 moles × 1 mole/ 2 moles= 0.09895 moles of bromine

Mass of bromine produced= number of moles × molar mass

Molar mass of bromine= 2(79.904)gmol-1

Mass of bromine= 0.09895 moles × 2(79.904) gmol-1

Mass of bromine= 15.8 g

explanation:

the largest database of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. the number of potential organic compounds has been estimated at 1060—an astronomically high number. the existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities. the simplest organic compounds contain only the elements carbon and hydrogen, and are called hydrocarbons. even though they are composed of only two types of atoms, there is a wide variety of hydrocarbons because they may consist of varying lengths of chains, branched chains, and rings of carbon atoms, or combinations of these structures. in addition, hydrocarbons may differ in the types of carbon-carbon bonds present in their molecules. many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory. we use hydrocarbons every day, mainly as fuels, such as natural gas, acetylene, propane, butane, and the principal components of gasoline, diesel fuel, and heating oil. the familiar plastics polyethylene, polypropylene, and polystyrene are also hydrocarbons. we can distinguish several types of hydrocarbons by differences in the bonding between carbon atoms. this leads to differences in geometries and in the hybridization of the carbon orbitals.

the answer is a. co2, this would be colder than the : )
