Question 2:
For question 2 you will need to search for some data in the
literature/internet for some of the questions.
2.1 Write down a balanced equation for the
reaction of potassium metal with water. Indicate the physical
states of all the reagents and products.
2.2 Calculate ΔH0 for the reaction of
potassium with water.
2.3 If that a chunk of potassium weighing
7.55 g is dropped into 400.0 g of water at 25.0 0C, what is the
final temperature (in 0C) of the water if all the heat released is
used to warm the water?
2.4 Calculate the molarity of the KOH
solution prepared in question 2.3.
2.5 How many millilitres of a 0.554 M
H2SO4 solution are required to neutralize the solution in question
2.4?
