Answer: The unknown solution had the lower concentration
Explanation: concentration will always move from higher to lower region. If the concentration of the unknown solution has increased, it therefore means that the initial concentration of the unknown solution was low
Hi there!
Rutherford's experiment showed that the atom's nucleus <em>did </em>have a positive charge. The α particles' trajectory was altered when it went through the gold foil, which, in turn resulted in the discovery of the atom's positive charge.
I hope this helps!

Answer:
number of individuals
Explanation:
calculated by dividing the number of people by area
Answer:
0.0125 mol.
Explanation:
<em>Molarity of a solution is the no. of moles of a solute per 1.0 L of the solution.</em>
<em></em>
M of HCl = 0.5 mol/L.
V = 25.0 mL = 0.025 L.
<em>∴ no. of moles of HCl present in the flask at this time = MV</em> = (0.5 mol/L)(0.025 L) = <em>0.0125 mol.</em>
