1. Maintains muscles strong and healthy
2. Allows blood to move smoothly
3. Can remove stress (makes you feel better)
4. It prevents pollution in the air
5. Helps you lose weight
In the first chart (NH4)2SO4
Nitrogen is 2
Hydrogen is 8 (h4*2)
Sulfur is 1
Oxygen is 4
For the second chart
Nitrogen i believe is 2
Hydrogen would be 10
Sulfur would should 1
and Oxygen should be 4
The balance that can be used to measure a mass reading of 0.90 g will be a balance with ±0.01 g tolerance.
The mass reading balance used for measurement
1.230 g ±0.001 g tolerance
5.43g ±0.01 g tolerance
4.0000g ±0.0001 g tolerance
6.539g ±0.001 g tolerance
<h3>What is the tolerance of a balance?</h3>
The tolerance of a balance is the number of decimal place values shown on the balance and it is the permissible limitations measured in grams, that a balance can tolerate.
- Hence, depending on the decimal place value behind a mass reading will determine the balance used for measurement.
From the given parameters:
The mass reading balance used for measurement
0.90 g ±0.01 g tolerance
1.230 g ±0.001 g tolerance
5.43g ±0.01 g tolerance
4.0000g ±0.0001 g tolerance
6.539g ±0.001 g tolerance

Answer:
Explanation:
Potassium nitrate is a soluble salt which readily dissolves in a polar solvent, such as water. When solid potassium nitrate is dissolved in water, it dissociates into potassium cations and nitrate anions.
Due to the resultant ionic charges, the polar water molecules attract the resultant ions and potassium nitrate ions become hydrated, that is, surrounded by water molecules.
Nitrate, our anion, attracts the partially positive ends of water molecules by attracting them via hydrogen atom.
Potassium, the cation, attracts the partially negative end of water molecules by attracting via oxygen atom.
