Answer:
4: Hydro electrical energy
5:Flase the law of conservation of energy is not violated by transformer.
Explanation:
4:Hydroelectric energy, also called hydroelectric power or hydroelectricity, is a form of energy that harnesses the power of water in motion—such as water flowing over a waterfall—to generate electricity. People have used this force for millennia.
5:Quantum Physics and Law of Conservation of Energy.
Niels Bohr, Hans Kramers, and John Slater proposed that these electrons violated the law of conservation of Energy momentarily. They stated that with each jump, energy is either created or destroyed by the electrons during the whole process.

Answer:
6 moles of SO₃ formed.
Explanation:
Given data:
Number of moles of SO₃ formed = ?
Number of moles of oxygen react = 3 mol
Solution:
Chemical equation;
2SO₂+ O₂ → 2SO₃
now we will compare the moles of oxygen and sulfur trioxide.
O₂ : SO₃
1 : 2
3 : 2/1×3 = 6 moles
Thus, six moles of SO₃ will formed.
