Melatonin is a powerful antioxidant and free radical scavenger that helps 'cool down' excess inflammation.
In fact, melatonin is so integral to the health of your immune system
that a lack of it causes your thymus gland, a key component of your
immune system, to shrink in size.1
Because melatonin is a strong antioxidant and is able to cross the
blood-brain barrier, it is thought to help protect against Alzheimer's
disease as well as brain aging.
In one study, artificially aged mice treated with melatonin had reduced
oxidative stress and markers of cerebral aging and neurodegeneration,
indicating the melatonin offered both neuroprotective and anti-aging
effects.2
In another study, researchers revealed that combining daily exercise
with the daily intake of melatonin appeared to have a synergistic effect
against brain deterioration in mice with Alzheimer's disease-associated
mutations.3 Improvements in behavior, learning and memory were noted.
Melatonin's immediate precursor is the neurotransmitter serotonin,
which is a major player in regulating and giving a lift to your mood.
And, like serotonin, melatonin plays important roles in your physical
and mental health. Studies have shown that insufficient melatonin
production can set you up for:</span>

Answer:
Mass of HCl = 73 g
Explanation:
Given data:
Mass of hydrogen = 2 g
Mass of HCl = ?
Solution:
First of all we will write the balance chemical equation:
H₂ + Cl₂ → 2HCl
Number of moles of hydrogen = 2 g/ 2g/mol
Number of moles of hydrogen = 1 mol
Form balanced chemical equation compare the moles hydrogen with HCl.
H₂ : HCl
1 : 2
Mass of HCl:
Mass of HCl = number of moles × molar mass
Mass of HCl = 2 mol × 36.5 g/mol
Mass of HCl = 73 g
