The heat of fusion AH, of tetrahydrofuran (C,H,O) is 8.5 kJ/mol. Calculate the change in entropy AS when 946. g of tetrahydrofuran melts at – 108.5 °C. Be sure your answer contains a unit symbol and the correct number of significant digits.
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.
#1 Solve the problem, please read directions carefully. Thumbs up if you do it correctly. Be sure to round your answer to the correct number of significant figures. Please see the example I provided in the screenshot.
The answer should be in this type of format with this unit symbol -- (example: 0.0057 kJ/K)
