1. Briefly explain why we expect to see the mass go up as the iron undergoes a reaction in this experiment.2. Magnesium undergoes a similar reaction with oxygen. Write the balanced chemical equation for the reaction between magnesium and oxygen gas. 3. Consider a reaction where 0.432 g of magnesium ribbon undergoes the above reaction to make 0.745 g of magnesium oxide as a product. How many moles of magnesium are in the final product? How many moles of oxygen?

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.
