Density measures how tightly packed opposed to how heavy like water is denser than oil.
Answer:
Your hypothesis is an educated guess of what the end results of an experiment will be, using what you already know about your experiment you are going to conduct. So when you receive your final results, if your hypothesis is correct, or even somewhat correct then you know that it is supported by your results. For example, if I were to conduct the Coca-Cola and Mentos experiment, I could make a hypothesis that the Coca-Cola will have a bigger eruption when I add more than one Mento to the bottle due to a higher amount of a chemical with the addition of each mento. When I receive my results that the eruption was bigger each time, I know that my results supported my hypothesis.

Answer is: <span>the coefficient of phosphoric acid is 12.
</span>Chemical reaction: P₄S₃ + NO₃⁻ + H⁺ → H₃PO₄ + SO₄⁻ + NO.
Reduction half reaction: NO₃⁻ + 4H⁺ + 3e⁻ → NO + 2H₂O /·38
Oxidation half reaction: P₄S₃ + 28H₂O → 4H₃PO₄ + 3SO₄²⁻ + 44H⁺ + 38e⁻ /·3.
38NO₃⁻ + 152H⁺ + 3P₄S₃ + 84H₂O → 38NO + 76H₂O + 12H₃PO₄ + 9SO₄²⁻ + 132H⁺.
Balnced chemical reaction:
3P₄S₃ + 38NO₃⁻ + 20H⁺ + 8H₂O → 12H₃PO₄ + 9SO₄²⁻ + 38NO.
Answer: 1.01 x 10^20 microliters.
Explanation: volume is defined as a three-dimensional measure of space that comprises a length, a width and a height. In other words, we are asked to convert from one volumetric measure to another (cubic centimeters to microliters) —volume is measured in units of cubic centimeters in metric, cubic inches or cubic feet in English measurement.
If, 1 cm³ = 1000 uL (microliters) then,
1 uL - - - - - - - - - 0.001 cm³ = 1 x 10^-3 cm
x uL - - - - - - - - - 1.01×10^-23 cm³
Therefore,
x uL = 1.01 x 10^-23 cm³ / 0.001 cm³
x uL = 1.01 x 10^(-23 - - 3)
x uL = 1.01 x 10^( - 23 + 3)
x uL = 1.01 x 10^20
Which is to say that a single rhodium atom of volume 1.01 x 10^23 cm³ would occupy 1.01 x 10^20 microliters.
