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.
Answer:
Intermolecular forces are the forces that bind two molecules together. Physical properties are affected by the strength of intermolecular forces. Melting, boiling, and freezing points increase as intermolecular forces increase. Vapor pressure decreases as intermolecular forces increase. Hope this is what your looking for!
Explanation:
Brainliest please?
No, they both refer to the ratio of moles in compounds of a chemical reaction. Along with mole ratio and molar ratio, this can also be called the mole-to-mole ratio.
Hope this helped :)
