Rutherford's experiment was done to prove Thompson's Plum Pudding Model. In this model, the protons and electrons are both inside the nucleus. The atoms is neutral because the charges cancel out. Rutherford's hypothesis was that, when a beam of cathode rays hits the gold foil, all the light should pass through. If the Plum Pudding model was correct, that would have been the result. However, it wasn't.
Answer:
The density increases.
Explanation:
As you go deeper in depth, pressure increases. Density = mass/volume. The layers beneath us due to pressure get packed to the point of being very dense.
Answer:
12 g
Explanation:
We want to prepare 1 L of a 0.15 M NaOH solution. The moles of NaOH required are:
0.15 mol/L × 1 L = 0.15 mol
The molar mass of NaOH is 40.00 g/mol. The mass corresponding to 0.15 mol is:
0.15 mol × (40.00 g/mol) = 6.0 g
The starting solution is 50% by weight. The mass of solution that contains 6.0 g of NaOH is:
6.0 g NaOH × (100 g solution/50 g NaOH) = 12 g solution
