Bohr display says obviously the electron spins around the core in orbit. so circle implies a circular locale around core.
The major product obtained when 1-hexyne is treated with H2 and Pd is; 1-hexene.
The structure of 1-hexyne is such that it possesses a triple bond around its first Carbon in it's carbon chain.
On this note; hydrogenation by treatment with H2 and Paladium, Pd as catalyst yields 1-hexene as the major product.
PS: Paladium, Pd is the major constituent of the Lindlar's catalyst.

Answer:
24.082 liters
Explanation:
You can solve this question using ideal gas formula. There are a few factors that will determine the volume(V) of gas, the number of the gas molecules (n), pressure(P), and temperature(T). You also need coefficient (R) which will depend on the unit used in pressure. We will use R= 0,08206 L atm K-1 mol-1 here. Don't forget to change the Celcius temperature into Kelvin.
PV=nRT
V= nRT/P
V = 0.08206 L atm/Kmol * (35+273.15) K /1.05 atm
V= 24.082 L

Required Answer :- </h2>
- In the question it is asked how many numbers of protons are present in a sodium atom.
- We know that the atomic number of sodium is 11.
- Sodium atom means it is in its neutral state, the neutral sodium atom has no charge on it.
- We know that the atomic number of an element is always equal to the number of protons for the particular element.
- Therefore the atomic number of sodium is 11 and the number of protons in sodium are 11.
<h3>Additional information :- </h3>
- If we know the atomic number of an element then only we can find the number of protons, neutrons and electrons present in it. The number of electrons in an element is equal to the atomic number of the respective element
- The atomic weight of the sodium is 23.
- The number of neutrons in sodium = Atomic weight of sodium – number of protons in sodium
= 23 – 11 = 12.
- So, the number of neutrons in sodium is equal to 12.
- The number of electrons in sodium is equal to the atomic number of sodium. Then the number of electrons in sodium is equal to 11.
- Therefore the number of protons, neutrons and electrons in sodium are 11, 12 and 11 respectively.
