Condensation and Hydrolysis | RiverVenture

The first reaction shown is a condensation reaction. Two molecules combine with the loss of a water molecule (blue and orange).

The second reaction is a hydrolysis reaction. A molecule is cleaved by the addition of water.

Standards

• Earth Science: Weather and Climate
  • 4.E.2 The student will demonstrate an understanding of the water cycle and weather and climate patterns.
    • 4.E.2A Earth’s atmosphere is a mixture of gases, including water vapor and oxygen. The movement of water, which is found almost everywhere on Earth including the atmosphere, changes form and cycles between Earth’s surface and the air and ba...
      • 4.E.2A.2 Develop and use models to explain how water changes as it moves between the atmosphere and Earth’s surface during each phase of the water cycle (including evaporation, condensation, precipitation, and runoff).
• Earth Science: Earth’s Weather and Climate
  • 6.E.2 The student will demonstrate an understanding of the interactions within Earth’s systems (flow of energy) that regulate weather and climate.
    • 6.E.2A Earth’s atmosphere, an envelope of gases that surround the planet, makes conditions on Earth suitable for living things and influences weather. Water is always moving between the atmosphere (troposphere) and the surface of Earth as a resul...
      • 6.E.2A.3 Construct explanations of the processes involved in the cycling of water through Earth’s systems (including transpiration, evaporation, condensation and crystallization, precipitation, and downhill flow of water on land).
