Should be an igneous rock.
Answer:
The correct answer is option a.
Explanation:
Diffusion flux is defined as movement of mas of atoms diffusing through the unit area in per unit time.It measured in (
).
J = diffusion flux
A = Unit area A through which atoms moves.
M = mass of atoms passes in t interval of time.

Answer:
24%
Explanation:
From the question, the limiting reactant is H2S.
The reaction equation is;
2H2S + O2 → 2S + 2H2O
Number of moles of H2S reacted = 22g/34 g/mol = 0.647 moles
According to the reaction equation;
2 moles of H2S yields 2 moles of sulphur
0.647 moles of H2S yields 0.647 moles of sulphur
So;
Theoretical yield of sulphur = 0.647 moles * 32 g/mol = 20.7 g
Actual yield = 5 g
% yield = actual yield/theoretical yield * 100
% yield =5 g/20.7 g * 100
% yield = 24%
The Nitrogen (N) will have the greatest attraction for the chlorine electrons.
Answer: A) N
Explanation
The tendency or the ability to attract electrons is termed as electronegativity.
The electronegativity tend to increase from left to right in the periods and bottom to top in the groups of the periodic table. So it is known that the halogen group consists of the most electronegative elements.
Though chlorine has high electronegativity of 3.16, the electrons of chlorine can be attracted by other electronegative elements provided that their electronegativity should be in the range of the electronegativity of Cl.
So among the elements given, Nitrogen (N) has an electronegativity of 3.04, Phosphor (P) has an electronegativity of 2.19 and Arsenide electronegativity is 2.18.
Thus it can be seen that the electronegativity is maximum for Nitrogen among the three elements so it should have the greatest tendency to attract Cl electrons.
