<span>In a salt solution (a solution of water (H2O) and Salt, chemical formula NaCl), the positively charged Hydrogen atoms from water form bonds with the negatively charged Chloride atoms of Salt (which is the formulate NaCl), and the negatively charged oxygen atom of water (one atom per water molecule) form a bond with the positively charged Sodium ions (Na) of salt.</span>
The modern day model of an atom has a lot of questions answered about it answered and is very accurate while John's version was a very early model before technology was advanced enough to get more information on it so it was very basic and not as accurate as today's model. Hope this helps!
The pigment is called chlorophyll and it’s job is to absorb light- usually sunlight
Answer:
The concentration of the pyridinium cation at equilibrium is 1.00×10⁻³ M
Explanation:
In water we have
C₅H₅NHBr + H₂O ⇒ C₅H₅NH+ + Br−
Pyridinium Bromide (C₅H₅NHBr) Dissociates Completely Into C₅H₅NH+ And Br− as such it is a strong Electrolyte.
Therefore the number of moles of positive ion produced per mole of C₅H₅NHBr is one
pH = - log [H₃O⁺] Therefore 10^-pH = [H₃O⁺] = concentration of C₅H₅NHBr
= 10⁻³ = 0.001M = concentration of C₅H₅NHBr
The concentration of C₅H₅NHBr is = 1.00×10⁻³ M to two places of decimal
