A teacher sprinkles some iron shavings on a clear tray . She places two magnets in the shavings with the north ends facing each other . Based on the cause-and-effect relationship between the magnets, which phenomenon is the teacher modeling for her students ?

answer: at room temperature (roughly 20 degrees c), you can dissolve 203.9 grams (or 200 grams) of sugar in 100 ml of water. as water temperature increases, the amount of sugar that will dissolve increases, up to about 500 grams of sugar in 100 ml water at 100 degrees c.

explanation:

i think   the answer is c hope i'm right

i do not get it   at all

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
