Answer: Polarity is the dipole-dipole intermolecular forces between the slightly positively-charged end of one molecule to the negative end of another or the same molecule
An example is H2+ (SO4)2- in Tetraoxosulphate (VI) Acid
Explanation:
In the acid H2SO4, ionization results in the formation of a Positively charged hydrogen ion (2H+) and a negatively charged Sulphate ion (SO4)2-
The slightly positive and negative parts in the ACID generates the DIPOLE (two poles) and THUS explains polarity
The pressure of the gas is 3.52 atm
<u><em>calculation</em></u>
This is calculated using the Boyle's law formula
that is P1V1= P2V2 where;
P1 = 1.65 atm
V1 =22.8 L
P2 =? atm
V2 = 10.7 L
make P2 the subject of the formula by dividing both side by V2
P2 = P1V1 / V2
P2 = (1.65 atm x 22.8 l) / 10.7 L = 3.52 atm
Money so i can get a nice body with the money hahah
Reduction. B is the correct answer
1. Only chlorophyll b absorbs some green light. Chlorophyll a absorbs wavelengths of blue-violet and orange-red light while chlorophyll b absorbs wavelengths of green light. I hope this answer helps you out!
