While traveling to a distant universe, you discover the hypothetical element. You obtain a representative sample of the element and discover that it is made up of two Isotopes, X-23 and X-25. To help your science tear calculate the atomic mass of the substance, you send the following drawing of your sample with your report. In the report, you
also inform the science team that the light atoms are X-23, which have an isotopic mass of 23.02amu, and the dark atoms areX-25, which have an isotopic mass of 25.147amu.
What is the atomic mass of element X

Sally is making a model of a magnesium atom with an atomic mass number of 24 for her chemistry class. she has foam balls for the protons, neutrons, and electrons. she has added 6 neutrons to her model so far. how many more neutrons does she need to add to complete her neutral atom of magnesium?

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.

What must be in balance for temperatures to remain constant?
