Many classic experiments have given us indirect evidence of the nature of the atom. Which of the experiments below did not give
taurus [48]

The Rutherford experiment proved the Thomson “plum-pudding” model of the atom to be essentially correct did not give the results described and is denoted as option A.

<h3>What is Thomson “plum-pudding” model?</h3>

This model was proposed by J.J Thomson in which referred an atom as a sphere of positive charge, and negatively charged electrons are embedded in it to balance the total positive charge.

This model was incorrect and the Rutherford atomic model was adopted in which he described the electrons orbits about a tiny positive nucleus.

The nucleus contains protons and neutrons instead thereby making it the correct choice.

The mass percentage of hydrochloric acid within a solution is 15.00%. given that the density of this solution is 1.075 g/ml, fin
Morgarella [4.7K]

Given the mass percentage of HCl solution = 15.00 %

This means that 15.00 g HCl is present in 100 g solution

Moles of HCl = 15.00 gHCl*\frac{1 mol HCl}{36.46 g HCl} =0.411molHCl

Density of the solution = 1.075 g/mL

Calculating the volume of solution from density and mass:

100 g *\frac{1mL}{1.075 g} =93.0 mL

Converting volume from mL to L:

93.0 mL * \frac{1 L}{1000 mL} =0.093 L

Calculating the molarity of HCl solution from moles and volume:

\frac{0.411 mol}{0.093 L} =4.42 mol/L
