Look at the chemical reaction below.

magnesium + hydrochloric acid → magnesium chloride + hydrogen

mg + 2hcl → mgcl2 + h2

in this reaction:
magnesium (mg) is a (reactant/product)
hydrogen (h2) is a (reactant/product)
magnesium chloride (mgcl2) is a (reactant/product)
hydrochloric acid (hcl) is a (reactant/product)

Glucose, also called grape sugar, blood sugar or corn sugar, is among the simplest and one of the primary naturally occurring sugars. produced naturally by plants as the primary photosynthesis product, it is heavily used by living beings as a main energy source and is necessary for cellular respiration. chemically, it is a monosaccharide carbohydrate and serves as a building block for complex sugars like starch.

What is the question? if you were looking to design a method of separating something, you can separate this compound by putting both in water and allowing the water to dissolve the sugar. then pour it into another beaker and evaporate it then boom! salt and sugar : ) 

The answer is c the potato slice shriveled because water moved out of the slice into the salt solution
