A chemist prepares a solution of silver(I) nitrate AgNO3 by measuring out ×4.7102μmol of silver(I) nitrate into a 450.mL volumet
Veseljchak [2.6K]

The concentration in /mmolL of the chemist's silver(I) nitrate solution is 0.01047 mmoles/litre.

Explanation:

Data given:

Number of moles of AgNO3 in micro mole 4.7102micromol.

The concentration is supposed to be in mmol so the micromole will be converted to milimole.

So, 1 micromole = 0.001 millimole

hence, 4.712micromole will be 0.004712 millimole.

Volume is given as 450ml which is converted into L

to convert ml into L it is divided by 1000

so 0.45 L is the volume.

Molarity or concerntration is calculated by the formula,

molarity = \frac{number of moles}{volume in litres}  

putting the values in the formula:

molarity = \frac{0.0047103}{0.45}

              = 0.01047 mmoles/litre is the molarity of AgNO3 solution in 450 ml of solution.

<span> 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>

valina [46]

Answer:

250ml

Explanation:

call it V

V*0.2=0.05 (moles)

so V=0.05/0.2 = 0.25l = 250ml

Part 1: Draw the major organic product for the proton transfer reaction between sodium hydride and ethanol; be sure to include l
valina [46]

Answer:

Major product ethoxide ion

Explanation:

  • Sodium hydride acts as a strong base towards ethanol.
  • Hydride ion abstracts one proton from -OH group in ethanol to produce sodium ethoxide and hydrogen gas.
  • It is an example of acid-base reaction where sodium hydride acts as a base and ethanol acts as an acid
  • Structure of major organic product i.e. ethoxide ion has been shown below.
