Total volume = 80 mL + 20 mL = 100 mL = 0.10 L.
NaOH + HCl ----> NaCl + H2O.
0.08 L * 2.00 mol NaOH/L = 0.16 moles NaOH.
0.02 L * 4.00 mol HCl/L = 0.08 moles HCl.
0.16 - 0.08 = 0.08. There are 0.08 moles NaOH XS.
0.08 moles NaOH produces 0.08 moles OH-.
Concentration OH- = 0.08 moles / 0.10 L = 0.8 M.
Explanation:
There should be 3 atoms in one molecule.
Answer:
Option A, The Rutherford experiment proved the Thomson "plum-pudding" model of the atom to be essentially correct.
Explanation:
Thomson's plum pudding model:
Plum pudding model was proposed by J.J Thomson. In Thomson's model, atoms are proposed as sea of positively charge in which electrons are distributed through out.
Result of Rutherford experiment:
As per Rutherford's experiment:
Most of the space inside the atom is empty.
Positively charge of the atom are concentrated in the centre of the atom known as nucleus.
Electrons are present outside the nucleus and revolve around it.
As it is clear that, result of Rutherford experiment did not supported the Thomson model.
