Ok so we had a lab and my teacher is currently unavailable right now and im mildly confused. we put sodium hydrogen carbonate into a test tube over a flame and lit a splint and stuck it into the mouth of the test tube. we also had to stick a piece of cobalt chloride testing strip into the mouth as well ( to test for moisture and or water vapor) which there was. anyways, we have to come up with a chemical equation for this reaction and the best thing i can come up with is nahco3. i have no clue where to go from here if you can i greatly appreciate

Which of the following best describes the formation of plasma?

How does the motion of particles in a gas change as the gas cools

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.
