1. A student mixes baking soda and vinegar in a glass. The results are shown at left. ... Yes I do belive that new substances are being formed because there is a chemical reaction between the baking soda and vinegar turning it into a bubbly substances instead of a powder and liquid.
Answer:
Mg(ClO₃)₂ ⟶ MgCl₂ + 3O₂
Explanation:
The reaction gives magnesium chloride and oxygen.
The balanced equation is then
Mg(ClO₃)₂ ⟶ MgCl₂ + 3O₂
A is <em>wrong</em>, because it is not balanced (12 O atoms on left and 6 O atoms on right).
C and D are <em>wrong</em> because they have the reactants as products and vice versa.

<span>The waveform shown on an oscilloscope is a signal graph of voltage as a function of time.
Such a signal isn't considered by the oscilloscope to be traveling, and
hence the oscilloscope itself doesn't see the signal as a wave.
In the wire though, it "sort of" is a longitudinal wave of
electrons...but then again, there is more to the story. There is also a
radio EM wave in the surrounding electric and magnetic fields, and the
engineers interested in long distance signal transmission study these
fields to estimate velocity factor. </span>
