According to Arrhenius concept a base is one which can donate hydroxide ion in its aqueous solution.
Here NaOH is a base as it can donate OH-.
As NaOH is a strong base it will have very high dissociation constant.
Due to high dissociation constant if will almost completely dissociate into sodium ions and hydroxide ions.
Thus in a solution of NaOH we will expect the following two ions
Na^{+} + OH^{-}[/tex]
Zinc is a Transition Metal. You can only know how many valence electrons Zinc loses by the valence electrons of Phosphorous. Because each Phosphorus atom needs 3 more electrons to become stable like Noble Gas. Meaning P wants a total of 8 valence electrons. So if it has 5, it needs 3 more to have a total of 8.
Zn3P2 is an Ionic compound. In the compound, there are 3 atoms of Zn, and 2 of P. If 1 atom of P needs 3 valence electrons, then 2 atoms of P will need 6 valence electrons. There are 3 atoms of Zn, that means each Zinc atom has 2 valence electrons. So, the number of atoms times the number of valence electrons is 6 valence electrons. 3(2) = 6. This 6 valence electron goes to P2 because P2 needs 6 valence electrons. So the net charge is 0.
So, based on all of those each Zinc atom loses 2 valence electrons.
The majority of wind turbines consist of three blades mounted to a tower made from tubular steel. There are less common varieties with two blades, or with concrete or steel lattice towers. At 100 feet or more above the ground, the tower allows the turbine to take advantage of faster wind speeds found at higher altitudes.
Turbines catch the wind's energy with their propeller-like blades, which act much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on one side of the blade. The low-pressure air pocket then pulls the blade toward it, causing the rotor to turn. This is called lift. The force of the lift is much stronger than the wind's force against the front side of the blade, which is called drag. The combination of lift and drag causes the rotor to spin like a propeller. So therefore your answer would be A.

The first diagram is showing carboxylic acid because carboxyl contains a Carbon atom as the central atom bonded with OH group, a double bonded Oxygen, hydrogen ofc, and a lone R group.
2. It is ester group
3. Correct its ether
4. It's the exact diagram for ethyl alcohol, so correct
