Answer:

0.0763 M  NaOH solution

3.05 g/mol  NaOH solution

Explanation:

NaOH + HCl ----> NaCl + H2O

1 mol      1 mol

M(NaOH)*V(NaOH) = M(HCl)*V(HCl)

M(NaOH) *86 mL = 0.0175M*375 mL

M(NaOH) = 0.0175M*375 mL/86 mL = 0.0763 M

0.0763 M = 0.0763 mol/L

M(NaOH) = 23 + 16 + 1 = 40 g/mol

0.0763 mol/L * 40 g/mol = 3.05 g/mol NaOH

Name three examples of how the atom has changed since Rutherford's discovery of the nucleus .
NikAS [45]

Answer:

Rutherford overturned Thomson's model in 1911 with his well-known gold foil experiment, in which he demonstrated that the atom has a tiny, high- mass nucleus. In his experiment, Rutherford observed that many alpha particles were deflected at small angles while others were reflected back to the alpha source.
