Answer: 7.68×10^14 J

Explanation:

The magnitude of the charge q1=q2 = 1.6×10^-19 C

Proportionality constant K = 9×10^9 Nm²/C²

Da= 2×10^-10m

Db= 3 ×10^-15m

W= k q1q2 ( 1/Db -1/Da)

W= 9×10^9 (1.69×10^-19)²(1/3.0×10^-15 - 1/2×10^-10)

W= 7.68 ×10^-14J

Therefore the amount of work requires is 7.68 ×10^-14J

How does atomic radius change from top to bottom in a group in the periodic table?
suter [353]
The atomic radius increases as you would go down a particular group on the periodic table of elements. This is because along with a greater number of protons, there would also be electrons as well, and thus the need of electron shells surrounding the atom would also be required, to compensate for the more electrons, as according to the bohr model, each shell contains 8 electrons in its electron shell. Thus the distance from the nucleus to the outermost shell increases, the atomic radius.

Which statement identifies the element arsenic?
insens350 [35]

Answer : Option A) Atomic number of Arsenic is 33.


Explanation : Arsenic contains same number of protons in its atomic nucleus. In arsenic there are 33 protons found in the atomic nucleus. Hence, the atomic number will be 33. It has 5 valence electrons in its outermost shell, which is also called as valence shell. So, its valency becomes 5.

The volume of a sample of nitrogen is 6.00 liters at 35oC and 0.75 atm. What volume will it occupy at STP?
joja [24]
The  volume that  will  occupy  at STP  is  calculated   as  follows
by use  of ideal  gas  equation
that is  PV=nRT  where n  is  number of  moles  calculate  number of moles

n= PV/RT
p=0.75 atm
V=6.0  L
R = 0.0821  L.atm/k.mol
T=  35  +273= 308k
n=?

n=  (o.75  atm  x  6.0 L)/( 0.0821 L.atm/k.mol  x 308 k)=  0.178 moles

Agt  STP  1 mole=  22.4 L  what obout  0.178 moles

=  22.4  x0.178moles/ 1moles =3.98 L( answer C)
