Sarah’s experiment shows that for every 10 centimeters of puck acceleration, the swing length increases by 50 centimeters.
Arsenic's atomic number is 33.
Hence his electronic configuration is
hence his valence electrons are

In chemistry, pH<span> is a numeric scale used to specify the acidity or basicity of an aqueous solution. It is approximately the negative of the base 10 logarithm of the concentration of hydronium ions. We calculate as follows:
pH = -log [H3O+]
pH = -log[</span><span>5.45 × 10–5 M]
pH = 4.3</span>
If new evidence or observations falsify a scientific theory, the theory will have to be changed to adapt to the new data or just discarded altogether.
