Answer:

Option B. A reaction that removes essentially all H+ and OH-

Explanation:

A neutralization reaction is a reaction involving acid and base to form salt and water only. In this reaction, the H+ from the acid is completely neutralize by the OH-

From the base. Hence, we can a neutralization reaction is a reaction that removes the H+ and OH- from reactant to form water. This is illustrated below

NaOH + HCl —> NaCl + H2O

Ionically:

OH- + H+ —> H2O

From the above, we see clearly that the reaction removed the H+ from the acid and OH- from the base to form water.

How many mols are present in the a sample of silver nitrate which has<br> 5.3x10^24 molecules.

Westkost [7]

Answer: 5.3 x 10^24 formula units of silver nitrate is equivalent to 8.8 moles of silver nitrate. Silver nitrate is an ionic compound, therefore, its representative particle is called a "formula unit" instead of molecule. For every mole of a substance, we know that there are 6.022 x 10^23 representative units of that substance. The amount of particles in one mole of substance is called Avogadro's number.

Further Explanation:

We can convert from number of representative particles to moles using the formula:

$\boxed {no. \ of \ moles \ = \ ( given \ no. \ of \ particles) \ (\frac{1 \ mole}{\ 6.022 \ x 10^{23} particles})}$

For this problem, we can calculate the number of moles by plugging in the given values to the equation above,

$no. \ of \ moles \ = (5.3 \ x \ 10^{24} \ formula \ units \ AgNO_{3}) \ (\frac{1 \ mole \ AgNO_{3}}{6.022 \ x 10^{23} \ formula \ units AgNO_{3}}) \\\\\boxed {no. \ of moles \ AgNO_{3} \ = \ 8.8 \ moles}$
