Water Chemistry

It is also described as an electrostatic attraction between a hydrogen atom, which is bonded to a highly electronegative atom, and a neighboring oxygen, nitrogen or fluorine atom.

• Hydrological Cycle

• Hydrogen Bond

It is a force that occurs between molecules.

What classification of water is the most convenient source for human activities?

• Groundwater

• Potable water

• Surface water

Potable water is contaminated with pollutants that include

particulates from dirt, toxic metals, or bacteria that cause cholera.

• TRUE

• FALSE

What is the process by which water is emitted from plants through the stomata, small opening on the underside of leaves that are connected to the vascular tissue?

• Transpiration

• Evaporation

• Evapotranspiration

• Precipitation

Biologically, the human body consists of about 71% water.

• TRUE

• FALSE

It is the fresh water found in underground reservoirs also known as aquifers.

• Surface water

• Groundwater

• Potable water

Is a water purification process that uses a semi-permeable

membrane to filter out unwanted molecules and large particles such as contaminants and sediments like

chlorine, salt, and dirt from drinking water.

• Filtration

• Reverse Osmosis

• Desalination

• Chlorination

It used to describe the combined losses of water due to transpiration and evaporation.

• Transpiration

• Evaporation

• Evapotranspiration

• Precipitation

It is a water treatment process where solids form larger clusters, or flocs, to be removed from water.

• Distillation

• Filtration

• Flocculation
