Answer:
THE answer is all of above
Explanation:
Answer:
Between carbon and silicon, silicon element has the strongest attraction between its nucleus and its valence electrons.
because silicon's nucleus is bigger than carbon.silicon loses electrons easily than carbon.
Noble gases belong to group 18 of the periodic table. These elements are inert because they have their valence orbital shells as ‘full’ hence do not participate in reactions since they cannot share electrons. These elements have a pattern in their electron configuration. Their outer most orbital shells has 8 electrons (with the exception of 2 for helium).
According to Dalton's Law of Partial pressure, the pressure exerted by a mixture of non-reacting gases is equal to the sum of their partial pressure.
Mathematically,
Total Pressure = P₍₁₎ + P₍₂₎ + P₍₃₎ + ....... ------(1)
Data given:
Partial pressure of Nitrogen = P₍₁₎ = 587 mmHg
Partial pressure of Oxygen = P₍₂₎ = 158 mmHg
Partial pressure of Argon = P₍₃₎ = 7.00 mmHg
Putting these values in eq 1.
Total Pressure = 587 mmHg + 158 mmHg + 7 mmHg
Total Pressure = 752 mmHg
