Enter a chemical equation for HI(aq) showing how it is an acid or a base according to the Arrhenius definition. Consider that st
jek_recluse [69]

Answer:

HI (aq) → H⁺ (aq) +  I⁻ (aq)

HI (aq) +  H₂O(l)  → H₃O⁺ (aq) +  I⁻ (aq)

Explanation:

The Arrhenius acid concept indicates that a substance behaves like acid if it produces hydrogen ions H⁺ or hydronium ions H₃O⁺ in water. A substance will be classified as a base if it produces OH⁻  hydroxide ions in water. This way of defining acids and bases works well for aqueous solutions.

When we mix HI (aq) and water, we are increasing [H₃O⁺]

HI (aq) → H⁺ (aq) +  I⁻ (aq)

HI (aq) +  H₂O(l)  → H₃O⁺ (aq) +  I⁻ (aq)

Reptile [31]

Rocks carried by the river smash together and break into smaller pieces. This process is called attrition.

Explanation:

  • Rocks carried by the river smash together and break into smaller pieces. This process is called attrition.
  • attrition is a form of coastal or river erosion, Attrition is an erosional process where rocks and pebbles are carried in the flow of a river.
  • Abrasion occurs when the breaking waves which contain sand and larger pieces erode the shoreline or headland of the shore.
  • When the rocks continue to collide with each other,they erode more and more, getting smaller and smaller until they are only sediment, this is when rocks that the sea is carrying
  • The amount of attrition depends upon the number of factors: particle properties such as its size, shape, surface,  hardness, and cracks.
  • It also have environmental properties such as time, velocity, pressure, shear, and temperature.
