Suppose that 523 mL of hydrogen gas are produced through a replacement reaction involving solid iron and sulfuric acid (H2SO4)
at STP. How much iron(II) sulfate is also produced?
Answer in units of g.

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.

Answer explain why it is not possible to deduce a complete order of reactivity.
