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.
Answer: a) 49.8 gram
b) 47.0 %
Explanation:
First we have to calculate the moles of glucose

The balanced chemical reaction will be,

From the balanced reaction, we conclude that
As,1 mole of glucose produce = 2 moles of ethanol
So, 0.54 moles of glucose will produce =
mole of ethanol
Now we have to calculate the mass of ethanol produced


Now we have to calculate the percent yield of ethanol

Therefore, the percent yield is 47.0 %
(a) f = 5.00 × 10²⁰ Hz, E = 3.32 × 10⁻¹³ J;
(b) f = 1.20 × 10¹⁰ Hz, E = 7.96 × 10⁻²⁴J.

The temperature at which phase changes occur is highly dependent on the electrostatic forces between the molecules in the substance.
The forces that hold molecules together are called intermolecular forces. These intermolecular forces affect the temperature at which phase changes occur. The statement about phase changes and electrostatic forces that is correct is that; "the temperatures at which a substance changes phases indicate the relative strength of the forces between molecules in the substance."
There are three states of matter, solid liquid and gas. The order of intermolecular forces in all the states of matter are not the same. The order of strongest collective electrostatic forces to weakest collective electrostatic forces is; solid, liquid, gas.
When water boils, the forces between water molecules break, and the bonds between the atoms in water are unchanged.
When a sample of calcium carbonate is cooled, the forces strengthen, and the molecule structure becomes more rigid.
If the boiling point of acetone is lower than the boiling point of ethanol, then, the intermolecular forces in ethanol are stronger than the intermolecular forces in acetone.
