Consider an element X that has two naturally occurring isotopes with the following percent abundances: the first isotope has a mass number of 84.912 and is 72.17% abundant; the second isotope has a mass number of 86.909 and is 27.83% abundant. What is the average atomic mass for element X?

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.

it is a solid

explanation:

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
