The following questions refer to the graph below, where sulfur trioxide is put into a sealed bottle and allowed to stand over ti
me. It will gradually decompose into sulfur dioxide and oxygen.
Q1. Write a balanced chemical reaction that is taking place inside the bottle
Q2. What would happen to the oxygen concentration if more sulfur trioxide is added to the bottle?
Q3. What would happen to the oxygen concentration if more sulfur dioxide is added to the bottle?
Q4.
If the bottle remained sealed, what would the concentration of SO3 be on day 10?
Q5. Using the above information and reaction, the best way to reduce the amount of SO3 in the atmosphere, and thus reduce the amount of acid rain is to?

Answer:
Explanation:
The work function of the sodium= 495.0 kJ/mol
It means that
1 mole of electrons can be removed by applying of 495.0 kJ of energy.
Also,
1 mole =
So,
electrons can be removed by applying of 495.0 kJ of energy.
1 electron can be removed by applying of of energy.
Energy required =
Also,
1 kJ = 1000 J
So,
Energy required =
Also,
Where,
h is Plank's constant having value
c is the speed of light having value
So,
Also,
1 m = 10⁻⁹ nm
So,
Answer:- 7 protons and 10 electrons.
Solution:- Atomic number for nitrogen atom is 7.
For neutral atom, atomic number = number of protons = number of electrons
An ion is formed if electrons are lost or gained by the neutral atom. Here we have nitride ion where nitrogen has -3 charge. This negative 3 charge indicates the gain of 3 electrons by nitrogen atom. The number of protons remains unchanged, means there are still 7 protons.
electrons for the given ion = 7 + 3 = 10
So, ion has 7 protons and 10 electrons.
