Answer:
Neutralization reactions occur when two reactants, an acid and a base, combine to form the products salt and water.
Polarity- a seperation of electric charge leading to a molecule having an electric dipole.
Molecular shape- I<span>dentify the central atom.
Count its valence electrons.
Add one electron for each bonding atom.
Add or subtract electrons for charge
Divide the total of these by 2 to find the total.number of electron pairs.
<span>Use this number to predict the shape.</span></span>
CO2 ~ 1 atom
N202 ~ 4 atom
CO ~ 2 atom
H2OS ~ 3 atom
B
This problem is giving information about the proton concentrations of three solutions at 25 °C. Despite they are not numerically given, we can propose three scenarios to see how to approach the question.
Let the following solutions to come up:
[H⁺] = 2.63x10⁻³ M
[H⁺] = 1.00x10⁻⁷ M
[H⁺] = 4.511x10⁻⁹ M
The first step, will be the calculation of the pH for each solution via:
pH = -log([H⁺])
So that they turn out to be:
pH = -log(2.63x10⁻³ M) = 2.580
pH = -log(1.00x10⁻⁷ M) = 7.000
pH = -log(4.511x10⁻⁹ M) = 8.3457
In such a way, since acidic solutions have a pH below 7, neutral have a pH equal to 7 and basic have it above 7, we infer the first one is acidic, second one is neutral and third one is basic.
Thus, you can reproduce this methodology with the proton concentrations you are given.
