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.
It will be nitrogen.
The energy associated with the formation of 1 mol of gaseous cations is The ionization energy. 1 mole of electrons will form 1 mole of gaseous atoms under standard conditions. The ionization energy decreases as you go down a group on the periodic table.
Answer:
they are different.
Explanation:
Pure substance only has one compound/element. While a solution has the same composition throughout, it still has two or more substances mixed in it.
