Write the balanced equation. Then calculate the volume of 0.65 M HCl required to completely neutralize 400.0 ml of 0.88 M KOH.

Misha Larkins [42]

Hello!

The balanced equation for the neutralization of KOH is the following:

HCl(aq) + KOH(aq) → KCl(aq) + H₂O(l)

To calculate the volume of HCl required, we can apply the following equation:

$moles HCl = moles KOH \\ \\ cHCl*vHCl=cKOH*vKOH \\ \\ vHCl= \frac{cKOH*vKOH}{cHCl}= \frac{400 mL*0,88M}{0,65M}= 541,54mL$

So, the required volume of HCl is 541,54 mL

Have a nice day!

What is ionization energy

damaskus [11]

Ionization energy is the energy required to remove an electron from a gaseous atom or ion. The first or initial ionization energy or Ei of an atom or molecule is the energy required to remove one mole of electrons from one mole of isolated gaseous atoms or ions

Question#31-32, I not sure and don’t know how to do,

LUCKY_DIMON [66]

Answer: 30. 7 moles SO3

31. 3 moles SO2 and 3 moles SO3

Explanation: To solve for this problem use the mole ratio of the substances involved in the reaction.

Solution for number 30:

3.5 moles O2 x 2 moles SO3 / 1 mole O2

= 7 moles SO3

31. 192 g SO2 x 1 mole SO2 / 64 g/ mol SO2

= 3 moles SO2

3 moles SO2 x 2 moles SO3 / 2 moles SO2

= 3 moles SO3
