Answer:
Option B. +3 and +6
Explanation:
<em>Zeff</em> = <em>z - s</em>
where <em>z</em> is the atomic number, <em>s</em> is the number of shielding(non-valence) electrons
For Boron, electronic configuration is 1s²2s³.
z = 5, s = 2
Zeff = 5 - 2 = +3
For Oxygen, electronic configuration is 1s²2s²2p⁴
z = 8, s = 2
Zeff = 8 - 2 = +6
I guess you mean viscosity
Anyhow the answer is milk
PV=PV
(602.1 L)(2.77atm) = (110.6 L) (X atm)
1667.817=110.6X
15.07971971 atm = X
Rounds to 15.1 (sig figs so much fun)
the compound is B.
Water is a compound because it is made up of water molecules.
Answer:
50 MHz
Explanation:
The relation between frequency and wavelength is shown below as:
c is the speed of light having value
Given, Wavelength = 6 m
Thus, Frequency is:
Also,
Also, 1 Hz = MHz
So,<u> Frequency = 50 MHz.</u>
