Answer:

15.71g

Explanation:

The combustion equation that applies to hydrocarbons is

CxHy + (x+y/4) O2 = xCO2 + (y/2) H2O

In the case of octane, C8H18:

C8H18 + ( 8 + 18/4 ) O2 = 8CO2 + 9H2O

C8H18 + 50/4 O2 = 8CO2 + 9H2O

C8H18 + 25/2 O2 = 8CO2 + 9H2O

2C8H18 + 25 O2 = 16 CO2 + 18H2O (this is the balanced equation)

From this balanced reaction,

2 x 22.4 L of octane generates 16 [ 12 + (16 x 2)] of carbon dioxide

That means,

44.8 L of octane generates 704g of carbon dioxide

Thus, for 1L of octane, it produces 1 L x 704g/44.8 L = 15.71g of carbon dioxide

Consequently, 15.71g of carbon dioxide is produced from the complete combustion of 1 L of octane.

Four students are developing a model to illustrate covalent and ionic substances dissolving in
Anarel [2989]

Students dealing with ionic bonds comprehend better how to convey what the model should showcase.

Explanation:

  • Upon dissolving ionic compounds in water, the compounds separate into their constituent ions via a process called dissociation.
  • The ions become attracted to water molecules, which carry a polar charge.
  • If the pull between the ions and the water molecules is strong enough to disband the ionic bonds, the compound dissolves.
  • The ions disperse in the solution, each surrounded by water molecules to inhibit reattachment.
  • The ionic solution forms an electrolyte, allowing it to conduct electricity.
  • In contrast, while covalent compounds do dissolve in water, they separate into molecules, not individual atoms.
  • Water acts as a polar solvent, yet covalent compounds are generally nonpolar.
  • This implies that covalent compounds often do not dissolve in water and instead form a distinct layer on top of the water.
