Answer:
Atomic number
Explanation:
Atomic number is the number of protons, and therefore also the total positive charge, in the atomic nucleus. The Rutherford–Bohr model of the hydrogen atom (Z = 1) or a hydrogen-like ion (Z > 1).
Answer:
Ethyl heptanoate (see the attached image for the structure).
Explanation:
- The reaction of heptanoic acid and ethanol will result ethyl heptanoate ester.
- Ethyl heptanoate is the ester resulting from the condensation of heptanoic acid and ethanol. It is used in the flavor industry because of its odor that is similar to grape.
- Kindly, see the attached image of the structure and the reaction.
Answer:
kinetic energy. (General Physics) the energy of motion of a body, equal to the work it would do if it were brought to rest. The translational kinetic energy depends on motion through space, and for a rigid body of constant mass is equal to the product of half the mass times the square of the speed.
Answer:
Explanation:
The correct statement is:
When 1 mol each of C₂H₅OH and CH₃CO₂H are allowed to react in 1 L of the solvent dioxane, equilibrium is established when 1/3 mol of each of the reactants remains. Calculate the equilibrium constant for the reaction. (Note: Water is a solute in this reaction.)
<u>1. Equilibrium equation</u>
- C₂H₅OH + CH₃CO₂H ⇄ CH₃CO₂C₂H₅ + H₂O
↑ ↑ ↑ ↑
ethanol acetic acid ethyl acetate water
<u>2. Equilibrium constant</u>
- Keq = [Products] / [Reactants], each raised to tis stoichiometrical coefficient.
Since water is also a solute in this reaction (the solvent is dioxane) its concentration will appear in the equilibrium constant.
<u>3. Equlibrium concentrations:</u>
Moles
C₂H₅OH + CH₃CO₂H ⇄ CH₃CO₂C₂H₅ + H₂O
Initial 1 1 0 0
Change -2/3 -2/3 +2/3 +2/3
End 1/3 1/3 2/3 2/3
Since the volume is 1 liter, the concentration is equal to the number of moles
<u>4. Calculations:</u>
Answer:
From Hawaii’s Maunakea, astronomers around the world use W. M. Keck Observatory to observe the universe with unprecedented power and precision.
The twin Keck Observatory telescopes are the world’s most scientifically productive optical and infrared telescopes. Each telescope weighs 300 tons and operates with nanometer precision. The telescopes’ primary mirrors are 10-meters in diameter and are each composed of 36 hexagonal segments that work in concert as a single piece of reflective glass.
In the middle of the Pacific Ocean, Hawaii Island is surrounded by thousands of miles of thermally stable seas. The 13,796-foot Maunakea summit has no nearby mountain ranges to roil the upper atmosphere. Few city lights pollute Hawaiian night skies, and for most of the year, the atmosphere above Maunakea is clear, calm and dry -— offering the best seeing on Earth.
