Answer: Option A) dissolving sugar in water
Explanation:
Sugar belongs to the class of food nutrients called carbohydrates, and it contains high energy bonds in its atoms that reacts with water thereby spontaneously releasing energy (in form of heat) to the surroundings.
Unlike others, energy is released when sugar is dissolved in water, thus the reaction is an example of exothermic reaction.
Answer:
C) Heat will transfer from the water to the air
Explanation:
This is a true statement.
Answer:
Include:
--Dot structures do not show the distribution of electrons in orbitals and take up a lot of space.
--Arrow and line diagrams take up a lot of space and make it difficult to count electrons.
--Written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
