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.
If o100 ml of 3. zero m solution were diluted to 250 ml awareness of<u> 1.2 M.</u>
The concentration of the solution tells you how tons solute has been dissolved within the solvent. for example, in case you upload one teaspoon to two cups of water, the awareness could be stated as 1 t salt in keeping with 2 c water.
V1 = one hundred mL, M1 = 3 M
V2 = 250 mL, M2 = ?
observe Dilution regulation
M1*V1 = M2*V2
so
M2 = M1*V1/V2
M2 = 100/250*3
M2 = 1.2 M
Concentration (normally uncountable, plural concentrations) The act, procedure, or capability of concentrating; the system of becoming focused, or the country of being concentrated. The course of interest to a particular object. The act, technique or product of reducing the quantity of a liquid,

<span>The simplest unit of matter that still retains the properties of an element is an "Atom".
Atom is the smallest particle of any unit that actually can exist retaining the properties of an element. </span><span />
Answer:
Explanation:
6.90 mol x grams
2As + 6NaOH = 2Na3AsO3 + 3H2
6 mol 2 mol
192 g/mol
6.90 mol NaOH x 2 mol Na3AsO3/6 mol NaOH== 2.3 mol Na3AsO3
2.3 mol Na3AsO3 x 192 g/mol = 442 g Na3AsO3
