What salt is produced in each of the following neutralization reactions? HNO3(aq)+KOH(aq)→H2O(l)+? HNO3(aq)+Ca(OH)2(aq)→H2O(l)+?
Igoryamba

Answer:

1. KNO3

2. Ca(NO3)2

3. CaCl2

4. KCl

Explanation:

In each of the neutralization reactions, the H from one of the reactant(acid) will combine with the OH from the other reactant (base) to form water while the other elements combine to give the salt as shown below:

1. HNO3 + KOH → H2O + KNO3

The salt produced is KNO3

2. 2HNO3 + Ca(OH)2 → 2H2O + Ca(NO3)2

The salt produced is Ca(NO3)2

3. 2HCl +Ca(OH)2 → 2H2O + CaCl2

The salt produced is CaCl2

4. HCl +KOH → H2O + KCl

The salt produced is KCl

How many particles are in a mole? 6.02 × 1023 23 × 106 602 billion 6.02 × 2310
Amanda [17]

Answer:

1mole=6.02x10^{23} unit (Avogadro constant)

Explanation:

It is known by the name of mole (mol) to one of the fundamental physical magnitudes that contemplate the International System of Units. This unit is used to measure the quantity of all kinds of substances present in a given system.

The mole, experts say, reflects the amount of substance that has a specific number of entities of elementary character as atoms can be found in twelve grams of carbon-12. This means that the number of elementary units (as in the case of atoms, molecules or ions, for example) that are reflected in a mole of substance is a constant that has no direct relationship with the type of particle or material in question. This amount is known as Avogadro's number.

This constant, baptized in homage to the scientist of Italian origin Amedeo Avogadro (1776-1856), allows to count microscopic particles from macroscopic measurements (as it is the case of the mass).
