Answer:
[H+] = 1.74 x 10⁻⁵
Explanation:
By definition pH = -log [H+]
Therefore, given the pH, all we have to do is solve algebraically for [H+] :
[H+] = antilog ( -pH ) = 10^-4.76 = 1.74 x 10⁻⁵
<u>Answer:</u> The correct answer is Option d.
<u>Explanation:</u>
Electronegativity is defined as the tendency of an element to attract the shared pair of electron towards itself in a compound.
When electron is transferred from less electronegative atom to more electronegative atom.
The atom which is more electronegative gains electron and undergoes reduction reaction.
Reduction reaction is defined as the reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

During the transfer of electrons, energy is released when an electron looses is potential energy during the transfer.
Hence, the correct answer is Option d.
First, the sun shines liquid (ocean) Next, the water evaporates
Answer:
Primary producers
Explanation:
Phytoplankton belong to the <u><em>primary producers</em></u> trophic level. Beings of the other levels gain energy from phytoplankton. Phytoplankton are also capable of transforming inorganic carbon into protoplasm.
The periodic table is an ordered way of representing chemical elements. They were ordered according to their atomic number, remember that the atomic number corresponds to the number of protons of the elements.
So the answer will be option C) Atomic Number
