To determine the amount of a certain element in a compound, we use the ratio of the elements from the compound. We calculate is follows:
45.0 g CCl4 ( 1 mol CCl4 / 153.82 g CCl4 ) ( 1 mol C / 1 mol CCl4 ) ( 12.01 g C / 1 mol C ) = 3.5135 g carbon present
Hope this answers the question. Have a nice day.
Ionic bonds have high emelting point amf boiling point while covale t bonds have low melting point and boiling point.
ionic bonds cannot conduct electricity in solid state but can conduct in the molten state or when dissolves in water. while covalent bonds cannot conduct electricity in any state.
ionic bonds are soluble in water but insoluble in organic solvents while most covalent bonds are soluble in organic solvents but insoluble in water
Density = mass/volume
density = 81 grams/0.9 cubic centimetersdensity = 90 grams per cubic centimeter
The density of the sample is 90 grams per cubic centimeter.
Answer:
Reactant : A combustion of hydrocarbon.
Explanation:
It is known that when hydrocarbons are involved in combustion, they produce carbon dioxide and water.
CxHy + (x+y/4)O2 ===> xCO2 + y/2H2O
