How many topics are there in chemistry?
There are five main branches of chemistry: physical chemistry, analytical chemistry, biochemistry, organic chemistry, and inorganic chemistry. Below is a brief description of each branch, although it is important to mention that many of these branches do overlap.
Why do M&M colors not mix in water?
When more than one M&M is placed into a petri dish the colors do not mix because the concentration of sugar at the interface is approximately the same. Also, around the bottom of the M&M water appears cloudy because the partially dissolved sugar is more dense than the water, so it sinks.
