Gas is a substance that will not phase change.
And vapor is a substance above it's boiling point temperature.
(3.500 mol MgO)(40.3044g MgO/1mol MgO)
=141.0654
Gas I think if I’m wrong it’s solid and if that’s wrong it’s liquid please give me brainliest
An exothermic reaction has occurred. You can remember that EXothermic means that energy is EXiting the system. If energy enters the system, it’s endothermic.
CaCO₃ → CaCl₂
Ca = 40, C = 12, O = 16, Cl = 35.5
100 →111
3 → x
x = 3.33g
