Double displacement/ Double decomposition/ Metathesis

Explanation:

The insoluble magnesium carbonate produced is called a precipitate. In a double displacement reaction, ionic compounds combines to produce precipitates.

In this type of reaction, species are usually exchange to form new compounds.

One of the following is a driving force for double displacement reaction:

  • Formation of insoluble compounds called precipitates.
  • Formation of water or any other non - ionizing compound
  • liberation of a gaseous product.

Europe and United States use geothermal power extensively.<br><br> True<br> False
fiasKO [112]

Answer:

True

Explanation:

US. With an installed capacity of 3,639MW in 2018, the US is the leading producer of geothermal energy across the world, producing 16.7 billion kilowatt hours (kWh) of geothermal energy throughout the year. More recently, extensive direct heat utilization projects have been undertaken in many European countries, and electric power developed extensively in Italy and Iceland. Geothermal heat pumps became extensively used in Austria, Switzerland, Germany and Sweden (Antice, Miklos and Sanner, Burkhard, 2007).

A buffer with a pH of 3.98 contains 0.23 M of sodium benzoate and 0.38 M of benzoic acid. What is the concentration of [H3O+] in
Vika [28.1K]

Answer:

New pH = 3.84

Explanation:

First of all we may think that if the buffer has pH 3.98 and we're adding H⁺, pH's buffer will be lower, as the [H⁺] is been increased.

Let's determine the moles of each compound:

0.23 M . 1.3L = 0.299 moles of NaBz

0.38 M . 1.3L = 0.494 moles of HBz

We add 0.058 of HCl, which is the same as 0.058 moles of H⁻

HCl →  H⁺  +  Cl⁻

As we add the moles of protons, these are going to react to the Bz⁻

In the buffer system we have these dissociations:

NaBz  →  Na⁺  +  Bz⁻

HBz →  H⁺  + Bz⁻

So, as we add protons, we have a new equilibrium:

          Bz⁻      +      H⁺       ⇄   HBz    

In    0.299         0.058          0.494

Eq   0.241               -              0.552

Protons are substracted to benzoate, so the [HBz] is now higher than before. We calculate the new pH, with the Henderson Hasselbach equation

pH = pKa + log (Bz⁻/HBz)

pH = 4.20 + log (0.241 / 0.552) → 3.84

Which substances are broken down by chemical means
solniwko [45]

Compounds

Explanation:

Compounds are substances that can be broken down by chemical means. They are categorized as pure substances due to their definite composition.

  • Compounds are substances composed of two or more kinds of atoms or elements joined together in a definite grouping.
  • Properties of compounds differs from those of the constituent atoms.
  • Compounds are broken down by chemical means because they are products of chemical changes.
  • Several kinds of compounds exists through combinations of atoms.
  • Compounds have definite compositions
