Rutherford's atomic structure model was revolutionary. Contrary to J.J. Thompson's "plum pudding" model (which consisted of a solid, even mixture of protons and electrons), Rutherford's model consisted of one small, positively charged, dense nucleus, a layer of empty space, and a layer of negatively charged electrons. He came to this conclusion through his gold-foil experiment. He shot a ray of alpha particles towards the thin gold foil, and to Rutherford's surprise, some of the rays reflected back instead of going straight through the foil as he originally thought.
I think is energy passing and if its not im so sorry :(((
Answer:
B. mass, volume
Explanation:
Density refers to a physical property that is measured using a ratio of mass divided by volume so that two objects of the same size can still have very different density.
Molarity is the number of moles of solute in one liter of solution whereas molality is the number of moles of solute present in 1 kilo gram of solution.
Molarity is denoted by M and molality denoted by m





Mass of solution

Density of solution = 1.1 g /mL
d = 1.1 = (W_B + W_A) /V

V = 910.11 mL
molarity of solution is:

= 0.0433 /0.910 = 0.0474 M
Thus, moalrity of solution is 0.0474 M
<h3><u>Answer;</u></h3>
D. Process B, because it is a spontaneous process.
<h3><u>Explanation</u>;</h3>
- A spontaneous process is one that will occur without any energy input from the surroundings.
- A spontaneous reaction may involve an increase or decrease in enthalpy, it may involve an increase or decrease in entropy, but it will always involve a decrease in free energy that is a negative ΔG.
- Therefore; process B is spontaneous since it has a negative ΔG
