Answer:
In a neutral solution the concentration of hydrogen ions is equal to the concentration of hydroxide ions
Explanation:
When:
[H⁺] > [OH⁻] the pH is acid, so the solution is practically acid.
When
[H⁺] < [OH⁻], the pH is basic, so the solution is practically basic
In neutral solutions:
[H⁺] = [OH⁻], so the pH is neutral (7)
pH > 7 → BASIC SOLUTIONS
pH < 7 → ACID SOLUTION
The 38 elements in groups 3 through 12 of the periodic table are called "transition metals". As with all metals, the transition elements are both ductile and malleable, and conduct electricity and heat. The interesting thing about transition metals is that their valence electrons, or the electrons they use to combine with other elements, are present in more than one shell. This is the reason why they often exhibit several common oxidation states. There are three noteworthy elements in the transition metals family. These elements are iron, cobalt, and nickel, and they are the only elements known to produce a magnetic field I HOPE THIS HELP:)
The mass percent of sugar in the solution is 1.225%
<u><em>calculation</em></u>
mass percent = [(mass of solute /mass of solution ) x 100]
mass of solute ( mass of a substance that dissolve in another substance)
= 2.45 g
mass of solution( mass of a substance that dissolves a solute) =200.0 g
Therefore mass percent = 2.45 g/200.0 g x 100 = 1.225% of sugar in solution
D, the energy of formation is equal to the dissociation. so from magnesium ions and Hydrogen ions, when they form the lattice energy is equal to formation-dissociation, as they aren't going to dissociate (fixed in lattice) the formation should be the same as the the overall lattice energy.
