Answer is: <span>pH of the water is 8.33, this is basic solution (pH is greater than seven).
</span>[H₃O+] = 4.60·10⁻⁹ M; equilibrium concentration of hydronium ion.
pH = -log[H₃<span>O+].
</span>pH = -log(4.60·10⁻⁹ M).
pH = 8.33.
pH (potential of
hydrogen) is a numeric scale used to specify the acidity or basicity <span>an aqueous
solution.

D magma is another form of a volcanic eruption.
<span>2.8 carat C x (0.20g C/ 1 carat C) x (1 mole C/ 12.01 g C) x (6.02 x 10^23 atoms C/ 1 mole C) = 2.8 x 10^9 atoms C
Use factor label method in order to determine the amount of atoms, make sure the units cancel.</span>
Since N2 is a covalent bond, the lewis dot structure of N2 would have a triple bond. Each bond contains 2 electrons, so if it has a triple bond it contains 6 electrons.
Calculate the number of valence electrons of N2
N= 2x 5 = 10
N2 has a total of 10 valence electrons, to become stable each N atom needs 8 electrons.
So, therefore, 6 electrons would have to be a part of covalent bonds because they share 6 electrons in a triple bond.
