Suna passes an electric current through a sample of clear, colorless, and odorless liquid. as the experiment continues, bubbles form, and the volume of liquid decreases. suna collects samples of two colorless, odorless gases that bubble out of the liquid. one of the gases burns. neither the original liquid nor the other gas burns.
which is the best explanation of her results?

a. the electric current changed some of the sample to gas even though the sample was not breaking down. therefore, the original liquid is a compound.

b. the electric current released a gas that was odorless and colorless, like the original sample. therefore, the original liquid is an element.

c. the sample was broken down by the electric current and formed a new substance that could burn. therefore, the original liquid is a compound.

d. the sample lost some of its volume, but the gas still had the same chemical makeup as the original sample. therefore, the original liquid is an element.

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.
