Progress through this unit of study we will add to your understanding of this type of change. For each of the numbered scenarios below, watch the video linked and answer the questions
that follow.
1. The reaction of iron and sulfur.
a. Watch the Iron and sulfur video
b. In the video you can observe iron reacting with sulfur to form a new substance,
iron (II)sulfide. Using our classification language, how would you describe iron,
sulfur and iron sulfide. In other words, what type of substance are each of these?
i. Iron:
ii. Sulfur:
iii. Iron (II) sulfide:
c. In the space below draw a formula unit for each of the substances
Iron
sulfur
iron (II) sulfide

Rutherford's experiment indicated that matter was not as uniform as it appears what part of his experimental results implied this idea

What is the relationship between wind and ocean waves? question 17 options: wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves. wind moving at higher speeds will transfer energy over a larger part of the ocean water, resulting in waves with a shorter wavelength. winds moving at higher speeds with cause water to move forward at faster rates, causing larger ocean waves. winds moving at higher speeds will affect deeper water, resulting in waves that move at a faster rate. how do temperature and salinity affect deepwater currents? question 15 options: 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.
