Did you hear about the claustrophobic astronaut?
I'd say true.
Matter is a physical substance that occupies space.
Lets say you put random stuff in a box. That stuff is matter, filling the box.
Its common to say that matter is everything around you. You can see everything around you (almost).

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:
The answer to your question is pH = 9.2; [OH] = 1.58 x 10⁻⁵
Explanation:
Data
[H⁺] = 6.0 x 10⁻¹⁰ M
pH = ?
pH definition. pH measures the hydrogen concentration. pH measures the acidity and the alkalinity of a solution. A solution is acid if the pH goes from 0 to 6.9, a neutral solution has a pH of 7 and an alkali solution has a pH from 7.1 to 14.
pOH measures the [OH⁻] concentration
Formula
pH = -log[H⁺]
pH + pOH = 14
-Substitution
pH = -log[6 x 10⁻¹⁰]
-Simplification
pH = - (-9.2)
pH = 9.2
-Calculate pOH
pOH = 14 - pH
pOH = 14 - 9.2
pOH = 4.8
-Calculate the concentration of OH⁻
pOH = -log[OH⁻]
[OH⁻] = -antilog4.8
[OH] = 1.58 x 10⁻⁵
