Answer: The heat capacity of the bomb calorimeter is 
.
Explanation:
Given mass of toluene = 1.55 g
Number of moles of Toluene:
Energy required by 0.0168 moles of toluene=
Since heat released on combustion of 0.0168 moles toluene, this heat will get absorbed by the bomb calorimeter ,then (Q) will be:
The heat capacity of the bomb calorimeter is .
Hydrocarbons contain only Carbon and hydrogen.
Hope this helps!
Answer: Option (C) is the correct answer.
Explanation:
When the volume of a container is decreased and same number of gas molecules are present inside the container at the same temperature then it means that more number of gas molecules are spread per unit volume.
As earlier when the volume of container was more then the molecules were widely spread inside the container but on decreasing the volume of container, molecules come closer to each other and hence there will be increase in molecules per unit volume.
You need to use the ideal gas law (PV=nRT) and solve for n. ((3.50atm•10.0L)/(0.0821(L•atm/mol•K)•304K) = n = 1.40 moles. 1 mole of Cl2 = 70.9 gm/mole. The mass would be 99.43 gm
"Iron and sulfur are both elements from the periodic table of elements. As such, each one has its own unique set of physical and chemical properties. Iron is a metal, while sulfur is a nonmetal. When these two are heated together, the iron atoms combine with the sulfur atoms to make a compound known as iron sulphide. A compound is different from elements in that it is made from the chemical union of two or more elements. Iron sulphide is not iron or sulfur; it is a pure substance with its own set of distinguishing physical and chemical characteristics. A mixture, on the other hand, is what you get by combining two or more elements, but not chemically combining them. In the case of the iron and the sulfur, if you mix them and provide no heat, you simply have a mixture of iron and sulfur. Mixtures are different from compounds in that they are easily separated. A magnet could be used to separate the iron from the sulfur, because iron is attracted to magnets, while sulfur is not." https://www.enotes.com/homework-help/explain-why-iron-sulphide-compound-not-just-336735 - I hope this helps! :)
