5 0

Answer:

Option B, HCO3 1-

Explanation:

The valence of Sodium ion is +1 and the valence of HCO3 is -1. Thus, sodium ion has an extra electron to be donated to complete its outer shell  while HCO3 needs an electron to complete its outer shell

Hence Na will combine with HCO3 to form NaHCO3

Option B is correct

Which element, if combined with chlorine, will have the greatest attraction for the chlorine electrons? N P As
motikmotik

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.

Maurinko [17]

The new pressure of the gas would be 505.58 torr

<h3>Boyle's law</h3>

According to Boyle's law, the pressure of a gas is inversely proportional to its volume, provided that the temperature is constant.

This can be mathematically represented as: P1V1 = P2V2

In this case, P1 = 759.4 torr, P2 is what we are looking for, V1 = 97.6 mL, and V2 = 146.6 mL

Hence, P2 = P1V1/V2 = 759.4x97.6/146.6 = 505.58 torr
