(a) If 83.0 g of ice at 0.0oC is placed in 235mL of water at 28.0oC, find the final temperature of water when all of the ice melts. DHfus=6.01 kJ/mol and assume for liquid water density= 1.00 g/mL
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
(a) If 83.0 g of ice at 0.0oC is placed in 235mL of water at 28.0oC, find the final temperature of water when all of the ice melts.
DHfus=6.01 kJ/mol and assume for liquid water density= 1.00 g/mL
HINT: you have two parts to find the heat.(remember that the heat lost must equal the heat gained).
Part a- find the heat for 83 g of ice melting and then the heat for the liquid to warm up
Part b- find the heat for 235 mL H2O to cool down
(b) What is the interpretation/finding from this problem?
