Chemistry
1 answer:
rodikova [14]4 years ago
4 0

Answer:

Explanation:

A chemical formula is representation of a compound. Compounds are made up of two or more elements combining together.

The chemical formula of any compound is a representation which shows the elements therein and the mole relationship expressed as subscripts.

  • For example, HCl;

          Elements in HCl -   Hydrogen (H)

                                          Chlorine (Cl)

Here 1 mole of hydrogen chloride molecule consists of 1 mole of chlorine atoms and 1 mole of hydrogen atoms.

The molar solubility of magnesium carbonate Mg(CO3) is 1.8 x 10-4 mol/L. What is the Ksp for this compound?
irina [24]

Answer:

The Ksp for this compound is 3.24 * 10^-8

Explanation:

Step 1: Data given:

Molar solubility of MgCO3 = 1.8 * 10^-4 mol /L

Step 2: Calculate molarity

For an insoluble compound, its molar solubility tells you how many moles of the compound can be dissolved per liter of aqueous solution before reaching saturation.

In this case, it means that we can only dissolve  1.8 * 10^-4 moles  in a liter of water at that temperature.

Moles Mg^2+ =  1.8 * 10^-4 moles

Moles CO3^2- =  1.8 * 10^-4 moles

Since we're working with one liter of solution, we can say the molarity:

[Mg^2+] =  1.8 * 10^-4 M

[CO3^2-] =  1.8 * 10^-4 M

Step 3: Calculate Ksp

Ksp = [Mg^2+]*[CO3^2-]

Ksp =  1.8 * 10^-4 *  1.8 * 10^-4

Ksp = 3.24 * 10^-8

The Ksp for this compound is 3.24 * 10^-8

Based on the diagram above, nitromethane has a chemical formula of CH
Ede4ka [16]

Answer:

Nitromethane, sometimes shortened to just Nitro, is an organic compound with the chemical formula CH

3NO

2. It is the simplest organic nitro compound. It is a polar liquid commonly used as a solvent in a variety of industrial applications such as in extractions, as a reaction medium, and as a cleaning solvent. As an intermediate in organic synthesis, it is used widely in the manufacture of pharmaceuticals, pesticides, explosives, fibers, and coatings.[12] Nitromethane is used as a fuel additive in various motorsports and hobbies, e.g. Top Fuel drag racing and miniature internal combustion engines in radio control, control line and free flight model aircraft.

Explanation:

Preparation

Nitromethane is produced industrially by combining propane and nitric acid in the gas phase at 350–450 °C (662–842 °F). This exothermic reaction produces the four industrially significant nitroalkanes: nitromethane, nitroethane, 1-nitropropane, and 2-nitropropane. The reaction involves free radicals, including the alkoxyl radicals of the type CH3CH2CH2O, which arise via homolysis of the corresponding nitrite ester. These alkoxy radicals are susceptible to C—C fragmentation reactions, which explains the formation of a mixture of products.[12]

Laboratory methods

It can be prepared in other methods that are of instructional value. The reaction of sodium chloroacetate with sodium nitrite in aqueous solution produces this compound:[13]

ClCH2COONa + NaNO2 + H2O → CH3NO2 + NaCl + NaHCO
