1. A main sequence star is any star that is fusing hydrogen in its core and has a stable balance of outward pressure from core nuclear fusion and gravitational forces pushing inward. An example is our sun

2. A giant star is any star having a relatively large radius for its mass and temperature

3. Supergiant stars form out of massive main-sequence stars that have run out of hydrogen in their cores.

4. When the pressure drops low enough in a massive star, gravity suddenly takes over and the star collapses in just seconds.

Answer:

Haven't evaporated all of the water

Explanation:

One of the main sources of error that occur in a formula of a hydrate lab is that all of the water is not evaporated. We can see at the end of the video that half of the CoCl2 is a light blue colors and the other half is a dark blue color. This indicates that all of the water still has not been evaporated off, resulting in the actual mass of the salt to be greater than the predicted value.
