The expression (PE products) - (PE reactants) represents the heat of reaction for a chemical change in terms of PE (potential energy).
<h3>What is potential energy?</h3>
Potential energy is any type of energy stored to perform physical work in a given period of time.
Conversely, kinetic energy is motion (movement) energy used when performing physical work.
In conclusion, the expression (PE products) - (PE reactants) represents the heat of reaction for a chemical change in terms of PE (potential energy).

Answer:
sinF = 3
/5 or 0.6.
Explanation:
Triangle ABC is a right triangle with its right angle at B. Therefore, AC is the hypotenuse of right triangle ABC, and AB and BC are the legs of right triangle ABC. According to the Pythagorean theorem,
AB=√202−162=√400−256=√144=12
Since triangle DEF is similar to triangle ABC, with vertex F corresponding to vertex C, the measure of angle∠F equals the measure of angle∠C. Therefore, sinF=sinC. From the side lengths of triangle ABC,
sinF = oppositeside
/hypotenuse = AB
/AC = 12/
20 = 3
/5
