Answer:
There are 12 protons, and 10 electrons in an Mg2+ ion, the normal amount of neutrons is 12.
Explanation:
The answer is 2 because if he is going at 12mph that he is going 6mph in 30min. So 8-6=2
Answer: The Ionization energy of Barium is lower and hence it can lose its electrons easily.
Explanation:
Ionization energy is defined as the energy required to remove an electron from an isolated gaseous atom. It is represented as
This energy will be higher for fully filled and half-filled electronic configuration than partially filled electronic configuration. This is so because half filled and fully filled configurations are stable.
Magnesium is the 12th element of the periodic table having electronic configuration of =
Barium is the 56th element of the periodic table having electronic configuration of
Both magnesium and barium belong to the same group as they have similar valence electrons. But as Barium is larger in size, the valence electrons lie farther from the nucleus and lesser energy is required to remove the electron and thus ionization energy will be lower for barium and thus will be more reactive.
Here we have to get the alcohols which are formed in the reaction of an alkene with H₂SO₄ and H₂O.
The alcohols which are formed in the reaction between alkene and H₂SO₄ and H₂O are majorly secondary and tertiary alcohol. As primary alcohol only ethanol can be produced in this reaction.
The addition of H₂SO₄/H₂O generates alcohol from alkene. The general reaction is shown in the figure. In this reaction methanol (CH₃OH) cannot be prepared and in primary alcohol only ethanol (C₂H₅OH) can be prepared from ethene.
In case of propene and other higher alkene always secondary or tertiary alcohols are produced as the addition of sulphuric acid and water depends on the Markonikov's rule of addition to the less hindered position.
