Answer:
⁶¹₂₉Cu + ⁴₂He --->⁶⁵₃₁Ga
Explanation:
Nuclear reactions are reactions which occur with changes in the nucleus of an atom. Nuclear reactions usually occur with the release of large amounts of energy and radiation. Radiactive elements are elements that are involved in nuclearbreactions due to the unstable nature of their nucleus. They disintegrate spontaneously with the emission of radiations. The major types of radiations released during nuclear reactions are;
1, Alpha particles - these are positively charged radiations with strong ionizing power. Each alpha particle is a helium nucleus
2. Beta particles - these are very fast moving stream of electrons. They are negatively charged particles .
3. Gamma radiation - is a form of electromagnetic radiation.
In the alpha absorption of Cu-61, the proton number of the atom increases by 2 while the mass number increases by 4 and the Cu-61 atom is changed to Ga-65 atom. The nuclear equation is given as follows:
⁶¹₂₉Cu + ⁴₂He --->⁶⁵₃₁Ga
Balanced chemical reaction: 2S + 3O₂ → 2SO₃.
1) Answer is: oxygen is limiting reactant.
n(S) = 3 mol; amount of sulfur.
n(O₂) = 4 mol; amount of oxygen.
From balanced chemical reaction: n(S) : n(O₂) = 2 : 3.
3 mol : n(O₂) = 2 : 3.
n(O₂) = (3 · 3 mol) ÷ 2.
n(O₂) = 4.5 mol; limiting reactant, because there is only 4 mol of oxygen.
2) Answer is: sulfur(S) is limiting reactant.
n(S) = 3 mol.
n(O₂) = 5 mol.
From balanced chemical reaction: n(S) : n(O₂) = 2 : 3.
n(S) : 5 mol = 2 : 3.
n(S) = 10 mol ÷ 3.
n(S) = 3.33 mol; there is only 3 mol of sulfur, so it is not enough.
3) Answer is: oxygen (O₂) is limiting reactant.
n(S) = 3 mol.
n(O₂) = 3 mol.
From balanced chemical reaction: n(S) : n(O₂) = 2 : 3.
3 mol : n(O₂) = 2 : 3.
n(O₂) = (3 · 3 mol) ÷ 2.
n(O₂) = 4.5 mol; limiting reactant, because there is only 3 mol of oxygen.

The correct option would be C. solid.
Think about it, the table in your dining room doesn't change shape does it?
It's because it has a definite shape.

Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is. Earth's gravity comes from all its mass.
