Answer:
The H+ (aq) concentration of the resulting solution is 4.1 mol/dm³
(Option C)
Explanation:
Given;
concentration of HA, = 6.0mol/dm³
volume of HA, = 25.0cm³, = 0.025dm³
Concentration of HB, = 3.0mol/dm³
volume of HB, = 45.0cm³ = 0.045dm³
To determine the H+ (aq) concentration in mol/dm³ in the resulting solution, we apply concentration formula;
where;
is initial concentration
is initial volume
is final concentration of the solution
is final volume of the solution
Therefore, the H+ (aq) concentration of the resulting solution is 4.1 mol/dm³
A negative ion or anion is an electrically charged atom or group of atoms that are formed by gaining one or more electrons. Whereas a positive ion or cation is an electrically charged atom or group of atoms that are formed by losing one or more electrons.
The losing and gaining all occurs on the outermost shell.
I think the correct answer from the choices listed above is option B. The list which includes three type of chemical reactions would be decomposition, single replacement, and double replacement. These are the most basic reactions in chemistry and are the basis for other types of reactions.
Answer:
Maybe try to memorize it by the valence electrons. You can do this!!
