Balance Chemical Equation:
A balanced chemical equation is that in which the number of the reactant atoms equal to the number of the product atom.
For example if the oxygen at the reactant side is 4, the number of oxygen must be 4 on the product side.
Solution
1. Au₂S₃ + H₂ --------> Au + H₂S
Balance Chemical Equation
1 Au₂S₃ + 3 H₂ --------> 2 Au + 3 H₂S
2. FeS + O₂ ---------> Fe₂O₃ + SO₂
Balance Chemical Equation
4FeS + 7O₂ ---------> 2Fe₂O₃ + 4SO₂
3. NH₃ + O₂ ---------> NO + H₂O
Balance Chemical Equation
4 NH₃ + 5 O₂ ---------> 4 NO + 6 H₂O
4. BaO + H₂O --------> Ba(OH)₂
Balance Chemical Equation
1 BaO + 1 H₂O --------> 1 Ba(OH)₂
Now by balancing all the atoms in equation are equal in reactant and product

Answer:
The only effect is that excess amount of energy absorbed by the electron will released to fall on lower energy state.
Explanation:
When transition occur from lower energy level to higher energy level require a gain of energy. Electron could not jump into higher energy level without gaining thew energy.
When electron jump into lower energy level from high energy level it loses the energy.
The process is called excitation and de-excitation.
Excitation:
When the energy is provided to the atom the electrons by absorbing the energy jump to the higher energy levels. This process is called excitation. The amount of energy absorbed by the electron is exactly equal to the energy difference of orbits.
De-excitation:
When the excited electron fall back to the lower energy levels the energy is released in the form of radiations. this energy is exactly equal to the energy difference between the orbits. The characteristics bright colors are due to the these emitted radiations. These emitted radiations can be seen if they are fall in the visible region of spectrum.
Answer:
The middle hydrogen is surrounded by 4 electrons
The middle hydrogen is bonded to 2 elements
There are too many electrons in the final structure
Explanation:
A mutation is a change in the DNA sequence.
