(Question 6 Essay Worth points) (07.05 HC) In an experiment, calcium carbonate reacted with different volumes of hydrochloric acid in water. One of the products formed during the experiment was carbon dioxide The time taken for 0.89 of carbon dioxide to form was recorded. A partial record of the experiment is shown. Flask Experimental Record Mass of Volume of Volume of Calcium Carbonate HCI Water Time: 4.09, 25, 11.2 seconds, 4.0, 20, 5 ml, 4.09, 15, 10 mL, 4.0, 10, 15. Why does the volume increase?

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.
