physical and chemical change
... A physical property is a property of a substance that can be observed without changing the substance into another substance. For example, the melting point of a solid is a physical property. Color, hardness, shape and texture are other physical properties. A chemical property is a property of a subs ...

... However, the measured value of hv 2f i departs from the predicted curves for f ⲏ10 kHz, except in the absence of electric noise. Our formulas were derived assuming a white spectrum for the random electric force. In the experimental setup, the spectrum of the electric signal is indeed flat but only ...

... 2 NH3 (g) ⇌ N2 (g) + 3 H2 (g) At 450.˚C, Kc = 6.30. An unknown quantity of NH3 is placed in a reaction flask (with no N2 or H2) and is allowed to come to equilibrium at 450. °C. The equilibrium concentration of H2 is then determined to be 0.342 M. Determine the initial concentration of NH3 placed in ...
