Imagine dissolving a spoonful of sugar in a glass of water. Is the sugar-water combination classified as a compound or a mixture? Explain your answer.

Homogeneous Mixture

Explanation:

A compound is when elements are chemically combined, through intermolecular bonding. A mixture is the physical combination of substances. In simpler terms, a compound is a pure substance, while a mixture is impure.  

In the sugar-water mixture, the sugar dissolves and is evenly distributed throughout the water. This makes it a homogeneous mixture.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
