What table are you talking about exactly ?
A distillation column is a process unit in which a feed mixture is separated by multiple partial vaporizations and condensations to form two or more product streams. The overhead product stream is rich in the most volatile components of the feed mixture (the ones that vaporize most readily).
Addition reaction between water molecules and alkene molecules produces alcohol.
<h3>What is addition reaction?</h3>
Addition reaction generally takes place across the unsaturated carbon compounds.
When water molecule (H₂O) is added to the alkene which may be ethene (C₂H₄) molecule then formation of product i.e. ethanol (CH₃CH₂OH) takes place through the addition of hydrogen and hydroxyl group across the double bond. And reaction is shown in the attached image.
Hence formation of alcohol product takes place.

M₁ = mass of water = 75 g
T₁ = initial temperature of water = 23.1 °C
c₁ = specific heat of water = 4.186 J/g°C
m₂ = mass of limestone = 62.6 g
T₂ = initial temperature of limestone = ?
c₂ = specific heat of limestone = 0.921 J/g°C
T = equilibrium temperature = 51.9 °C
using conservation of heat
Heat lost by limestone = heat gained by water
m₂c₂(T₂ - T) = m₁c₁(T - T₁)
inserting the values
(62.6) (0.921) (T₂ - 51.9) = (75) (4.186) (51.9 - 23.1)
T₂ = 208.73 °C
in three significant figures
T₂ = 209 °C
Answer:
-Isotope O-16 is the most abundant.
-Isotope O-16 has a mass number of 16 with 8 protons, 8 neutrons, and 8 total electrons.
-Isotope O-17 has a mass number of 17 with 8 protons, 9 neutrons, and 8 total electrons.
-Isotope O-18 has a mass number of 18 with 8 protons, 10 neutrons, and 8 total electrons.
Explanation:
Isotope O-16 makes up more than 99% of the Oxygen on the planet, and you can typically find which elements isotope is the most abundant by rounding its atomic mass to the nearest whole number. In this case you would round 15.9994 to 16 to determine that the the most common isotope of oxygen is O-16.
An elements mass number is equal to the sum of it's protons and neutrons and is used to identify isotopes. So in Oxygen's isotope O-16, the mass number is 16. An elements atomic number corresponds to how many protons are within it's nucleaus, this number does not change, regardless of the mass number. By subtracting the number of protons from the mass number of the isotope we can calculate the number of neutrons in each (16 - 8 = 8 neutrons) (17 - 8 = 9 neutrons) (18 - 8 = 10 neutrons).
In a neutral atom, or an atom with no charge, the number of electrons will equal the number of protons. So by using the atomic number of Oxygen we can calculate the number of electrons for each isotope, which would be 8 for all.
