Answer:
The see explanation
Explanation:
In this case, we have an <u>"amine"</u> group in the dopamine structure. So, the dopamine will act as a <u>"base"</u>. A base is a substance that has the ability to <u>accept hydrogens</u>, therefore, the 
will take hydrogen from the water molecule. Additionally, the water will produce the 
ion and the will be converted into 
.

The mass of chlorine required to react with 10.0 g of sodium metal to produce sodium chloride is 15.26 g.
The balanced chemical reaction is :
<em> 2Na + Cl₂ → 2NaCl</em>
<em />
Given data :
Mass of sodium = 10.0 g
Number of moles of Na -
Number of moles = <u> Given mass </u>
Molar mass
Number of moles = <u> 10.0 g</u> = 0.43 mol
23 g
Comparing moles of Na and Cl₂ from the balanced chemical equation,
Na : Cl₂
2 : 1
0.43 : <u> 1 </u> x 0.43 = 0.215 mol
2
Mass of chlorine gas :
(molar mass of chlorine = 71 g)
Mass of chlorine = number of moles x molar mass
Mass = 0.215 mol x 71 g/mol
= 15.26 g
