Answer:
Temperature
Explanation:
Temperature measures the average kinetic energy of the particles in a substance. Thermal energy measures the total kinetic energy of the particles in a substance. The greater the motion of particles, the higher a substance's temperature and thermal energy.
Answer is: the reducing agent is C₂H₅OH.
Balanced chemical reaction:
16H⁺ + 2Cr₂O₇²⁻ + C₂H₅OH → 4Cr³⁺ + 11H₂O + 2CO₂.
Oxidation half reaction: Cr₂O₇²⁻ + 14H⁺ + 6e⁻ → 2Cr³⁺ + 7H₂O/ ×2.
2Cr₂O₇²⁻ + 28H⁺ + 12e⁻ → 4Cr³⁺ + 14H₂O.
Reduction half reaction: C₂H₅OH + 3H₂O → 2CO₂ + 12H⁺ + 12e⁻.
Net reaction: 2Cr₂O₇²⁻ + 28H⁺ + C₂H₅OH + 3H₂O → 4Cr³⁺ + 14H₂O + 2CO₂ + 12H⁺.
Reducing agent is element or compound who loose electrons in chemical reaction. Ethanol (C₂H₅OH) lost electrons and it is oxidized to carbon dioxide (CO₂).
The morality of the solution that contains 5.0 moles of solute in 2 .0 liters in the solution is calculated as follows
molarity =moles/volume in liters
= 5 moles/ 2 l = 2.5M
The substance that would be least likely to dissolve in a polar solvent IS A NON POLAR MOLECULE.
Examples of non polar molecules are oil and cholesterol. These molecules are non polar, that is, their electrons are distributed evenly throughout the element and thus their charges cancel out one another. Such compounds will not dissolve in polar solvent.
