6.0 will the pH at the neutralization point of 0.00812 m Ba(OH)2 be when titrated with HCl.
<h3><u>What are </u><u>
titration reactions ?</u></h3>
A titrant/titrator, a standard solution with fixed volume and concentration, is prepared as part of the titration procedure. When an endpoint or equivalence point is reached, the titrant is made to continue reacting with the analyte, and at that point, the amount of titrant consumed may be used to calculate the analyte's concentration. Alternately, titration is the application of the stoichiometry principle to determine an unknown solution's concentration.
The technique begins by adding a very little quantity of analyte to a beaker or Erlenmeyer flask. Under a calibrated burette or chemical pipetting syringe containing the titrant, a little quantity of an indicator (such as phenolphthalein) is inserted.

The answer is c and i don’t know why
Answer:
K
Explanation:
Ionization energy refers to the energy required to remove an electron from an atom. It usually increases across the period due to the increase in the size of the nuclear charge and decreases down the group due to increase in the number of shells.
If we look at the element, K, it has only one electron in its outermost shell. This implies that after this one electron is removed, the second ionization energy involves the removal of an electron from a filled shell.
This usually requires a lot of energy. Hence, the element having the highest difference in energy between first and second ionization energy is K.
Gravity holds the earth together with gravity because of the earth's axis the earth spins causing seasons. And that also effects the period of orbit.
Volume can be measured in cubic centimetres (which is the small 3 next to the unit and is higher)
