_____ are a type of organic compound.a. Chlorides
b. Carbonates
c. Hydrocarbons
d. Nitrous oxides

Answers

Answer 1
Answer:

Hydrocarbons are a type of organic compound. The answer is letter C. Hydrocarbons contains a carbon, hydrogen and oxygen bond that makes it organic. Chlorides, carbonates and nitrous oxides are not organic compounds but they are inorganic compounds.
Answer 2
Answer: A hydrocarbon is a molecule whose structure includes only hydrogen and carbon atoms. Hydrocarbons containing between six and ten carbon molecules are the top components of most fuels. In general, these molecules are burned to produce energy. Examples such include: 1. Methane: A fuel in electrical generation. 2. Propane: Generally used heating and cooking. 3. Butane: Generally used in lighters and aerosol cans. 4.Heptane: The major component of gasoline Hydrocarbons are majorly used as a combustible fuel source and are considered a primary source of energy for contemporary civilizations. Oil is an excellent example of a hydrocarbon fuel currently in use all over the world.

Explanation:

What is the pH of an aqueous 0.032 M pyridine, (C5H5N)? (Kb for pyridine = 1.7 x 10–9)

Answers

pH + H₂O ⇋ [pOH]⁺ + OH⁻
 
Kb = [pOH⁺][OH⁻] / [ pH] = 1.7×10⁻⁹

Let x mol dissociate:

 [pOH⁺] = [OH⁻] = x [pH] = 0.032 - x ≈ 0.032

[x] [x] / [0.032] = 1.7×10⁻⁹

x₂ = 0.032 * 1.7 x 10⁻⁹

x = 5.44 x 10⁻¹¹ = [OH⁻] 

pOH = -log [OH⁻] = -log[  5.44 x 10⁻¹¹] = 10.26

pH = 14.00 - pOH 

pH = 14.00 -  10.26

PH = 3.74

Egi calculate 0.2 mole of H₂0 into Volume​

Answers

Answer:

To calculate the volume of 0.2 moles of H₂O (water), we need to use the relationship between moles, volume, and molar concentration. The molar volume of a gas at standard conditions (0°C and 1 atm pressure) is approximately 22.4 liters/mol. However, since water is in liquid form, we'll need to consider its density to calculate the volume.

The molar mass of water (H₂O) is approximately 18.01528 g/mol.

Given:

Moles of H₂O = 0.2 moles

Molar mass of H₂O = 18.01528 g/mol

We can calculate the mass of 0.2 moles of H₂O:

Mass = Moles × Molar mass

Mass = 0.2 moles × 18.01528 g/mol = 3.603056 g

Now, let's convert the mass to volume using the density of water. The density of water at room temperature (around 20°C) is approximately 1 g/cm³.

Given:

Mass = 3.603056 g

Density of water = 1 g/cm³

Volume = Mass / Density

Volume = 3.603056 g / 1 g/cm³ = 3.603056 cm³

So, the volume of 0.2 moles of H₂O is approximately 3.603 cm³ at room temperature and pressure.

When dissolved in water, an Arrhenius base yields(1) hydrogen ions (2) hydronium ions(3) hydroxide ions (4) oxide ions

Answers

Arrhenius bases yield hydroxide ions when in solution.  Arrhenius acids on the other hand yield hydrogen ions (which is sometimes called hydronium since the H⁺ turns to H₃O⁺ in water).

I hope this helps.  Let me know if anything is unclear.
