Answer:
Rutherford's experiment, also known as
supports the existence of neutrons and the nucleus.
Explanation:
In the above diagram, Rutherford was trying to explain his contributions using thin foils of gold and other metals as targets for alpha particles from a radioactive source.
He observed that the majority of particles penetrated the foil either undeflected or with only a slight deflection. But, every now and then an alpha particle was scattered(or deflected) at a large angle..
According to Rutherford, most of the atoms must be empty space. This explains why the majority of alpha particles passed through through the gold foil with little or no deflection. The atoms positive charges, Rutherford proposed are all concentrated in the Nucleus, <em>which</em><em> </em><em>is</em><em> </em><em>a</em><em> </em><em>dense</em><em> </em><em>central</em><em> </em><em>core</em><em> </em><em>withi</em><em>n</em><em> </em><em>the</em><em> </em><em>atom</em><em>. </em>
Whenever an alpha particle came close to a nucleus in the scattering experiment, it experienced a large repulsive force and therefore a large deflection. Moreover, an alpha particle coming towards a nucleus would be completely repelled and its direction would be reversed. The positively charged particles in the Nucleus are called Protons.

Answer : You can make 4.68 moles of SO₂
Explanation:
Step 1 : Write balanced equation.
S₈ can combine with oxygen to form SO₂ gas. The balanced equation for this reaction is written below.
Step 2 : Find moles of S₈
The formula to calculate mol is
Molar mass of S₈ is 256.5 g/mol
we have 0.585 mol of S₈
Step 3: Use mole ratio to find moles of SO₂
The mole ratio of S₈ and SO₂ can be found using balanced equation which is 1:8
That means 1 mol of S₈ can form 8 moles of SO₂.
Let us use this as a conversion factor to find moles of SO₂
Therefore we have 4.68 moles of SO₂
