Question

a student is given a sample of a blue nickel sulfate hydrate. she weighs the sample in a dry covered crucible and obtain a mass of 23.711 g for the crucible, cover, and a sample. earlier she had found that the crucible and cover weighed 21.594 g. she then heats the crucible to drive off the water of hydration, keeping the crucicle at red heat for about 10minutes with the cover slightly ajar. She then lets the crucible cool, and finds it has a lower mass; the crucible, cover and contents then weigh 22.840 g. In process the sample was converted to greenish-yellow anhydrous NiSO4

Answer 1

Answer:

Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science
