What kind of change occurs when salt dissolves in water? What is the enthalpy of vaporization of water? At what temperature does a liquid becomes a gas? Is water vapor a gas? Calculate the enthalpy change for the process in which 27.5 g of water is converted from liquid at 6.8 degrees...
Calcium oxide and carbon are reacted to produce carbon monoxide and calcium carbide CaC_2. When one mole of calcium carbide is formed, 464.8kJ is absorbed. What is the enthalpy of reaction when 1.00g Steam locomotives in the 1950 s burned coal contain...
When 1.20 mole of ammonia ( NH_3 ) reacts, what is the total number of moles of water formed? NH_3(g) + O_2(g) = NO(g)+H_2O(l) What is the difference between enthalpy change and enthalpy of reaction? How many moles of hydrogen are produced from the reaction of three moles...
What is the enthalpy of vaporization of water? The combustion of 0.1584 grams of benzoic acid increases the temperature of a bomb calorimeter by 2.548 degrees Celsius. a. Calculate the heat capacity of this calorimeter. (The energy released by the combustion of benzoic acid is 26.42 kJ/g.) ...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, ...
What is Condensation? - Condensation is the change of the physical state of matter from the gas phase into the liquid phase, and is the reverse of vaporization. Condensation is the process of a substance in a gaseous state transforming into a liquid stat
What are Minerals? - A mineral is a natural inorganic solid with a specific internal structure and a chemical composition that varies only within specific limits. Minerals are the solid constituent of earth. Visit BYJUS to learn more about it.
A molecular compound cannot conduct electricity in any state, whereas an ionic compound, when dissolved in an aqueous solution, can act as a good conductor of electricity. Ionic compounds are more reactive than molecular compounds. The enthalpy of fusion (heat energy absorbed when a solid melts)...
