The reaction below is a exothermic or endothermic reaction. 2SO3(g) + Heat ⇋ 2SO2(g) + O2(g)
Identify whether the following process are endothermic and exothermic.Justify your answer. 1. Burning of coal 2.Neutralization between an acid and base 3.Combustion of gasoline 4. Solid lead (II)chloride(PbCl2) dissolve only in hot water 5.Heating causes sodium bicarbonate (NaHCO3) to decompose.
A 5.43 g sample of an unknown salt (MM = 116.82 g/mol) is dissolved in 150.00 g water in a coffee cup calorimeter. Before placing the sample in the water, the temperature of the salt and water is 23.72°C. After the salt has completely dissolved, the temperature of the solution is 28.54°C. If -3.13 x 10 J of heat was lost during the dissolution reaction of 0.0465 moles of the unknown salt, what is the enthalpy change (in kJ/mol of salt) for the dissolution reaction? Type here to search
True or False: The test tube in which a chemical reaction is taking place feels warmer to the touch. The reaction is endothermic.
I need help with question #2.
1) A 0.416 g sample of KCl is added to 56.5 g of water in a calorimeter. If the temperature decreases by 1.24°C, what is the approximate amount of heat (in J) involved in the dissolution of the KCl, assuming the heat capacity of the resulting solution is 4.18 J/g°C? _____ J 2) Is the reaction exothermic or endothermic?
A 7.37 g sample of an unknown salt (MM = 116.82 g/mol) is dissolved in 150.00 g water in a coffee cup calorimeter. Before placing the sample in the water, the temperature of the salt and water is 23.72°C. After the salt has completely dissolved, the temperature of the solution is 28.54°C. What quantity in moles of the unknown salt were used in the reaction?
