Hi, can someone me with chemistry
question1: you begin with 2.0g of fe(nh4)2(so4)2*6h2o. how many moles is this?
question 2: you then add 10ml of 1.0 m oxalic acid, h2c2o4. how many moles is this?

100mg magnesium reacts with 20ml of 1.0m hcl

In an energy pyramid, which level has the most available energy?

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.
