Explanation:
de Broglie wavelength= h/mv
v=h/m x de Broglie wavelength
v= (6.626× 10^-34)/ (2347× 1.27 × 10^-38)
v= 22.229 m/s(according to Google scientific calculator)
am sorry I don't hv a calculator at hand
An example of the substnce would be steel
Solutions with pH less than 7 are acidic in nature.
Therefore, a substance of pH 6 will be a weak acid.
Answer:
