How does hard water affect the action of soap?
Ask: How does hard water affect the action of soap?
Answer:
When soap is added to hard water, the Ca2+and Mg2+ions present in hard water react with soap. The insoluble scm sticks on the clothes and so the cleaning capacity of soap is reduced. The cleaning action of soap is very effective in soft water because it contains negligible calcium and magnesium ions.

how does human hardnesses energy from the water?
Ask: how does human hardnesses energy from the water?
Answer:
When more energy is needed, water is released from the dam. Once water is released, gravity takes over and the water flows downward through a turbine. As the blades of the turbine spin, they power a generator. … As this water flows back down to the lower reservoir, it turns a turbine to generate more electricity.

● HARDWATER
is formed when water percolates through deposits of limestone, chalk or gypsum which are largely made up of calcium and magnesium carbonates, bicarbonates and sulfates. Hard drinking water may have moderate health benefits.
Additional Knowledge
Why is it called hard water?
Hard water does not describe the actual feeling of the water. Instead, it is called hard water because it has has mineral deposits like calcium and magnesium within the water molecules. … Water becomes hard when it seeps into the ground and absorbs calcium and magnesium.
What are the sources of hard water?
The principal natural sources of hardness in water are dissolved polyvalent metallic ions from sedimentary rocks, seepage and runoff from soils. Calcium and magnesium, the two principal ions, are present in many sedimentary rocks, the most common being limestone and chalk.
What is hard water examples?
•It is treated water.
•Soft water:

●GROUND WATER
The following characteristics of groundwater give it certain advantages over surface water.
1. Groundwater usually contains no suspended matter.
1. Groundwater usually contains no suspended matter.2.Groundwater, very rarely contains pathogenic bacteria; generally it contains microbes native to the formation, unless contaminated by human activity (Michael J. Schieders, Water Systems Engineering Inc., via personal communication.)

Temperatures can be altered by human influence.

●To be short the Answer is B. It is not just about the temperature outside but the inside should be included too,It is to detect how much hot or cold outside and inside is.
-Temperature is a physical quantity that expresses hot and cold. It is the manifestation of thermal energy, present in all matter, which is the source of the occurrence of heat, a flow of energy, when a body is in contact with another that is colder.
What causes temporary hardness in water? permanent hardness? How can
Ask: What causes temporary hardness in water? permanent hardness? How can they be removed?
Answer:
Temporary hardness is mainly caused by the carbonates and bicarbonates of calcium and magnesium. It can be easily removed by boiling of water. Permanent hardness is due to presence of sulfates and chlorides of calcium and magnesium in water.
Explanation:
Pls make it the brainliest answer
Answer:
Temporary hardness is a type of water hardness caused by the presence of dissolved bicarbonate minerals (calcium bicarbonate and magnesium bicarbonate). Boiling promotes the formation of carbonate from the bicarbonate and precipitates calcium carbonate out of solution, leaving water that is softer upon cooling.
Permanent hardness is hardness (mineral content) that cannot be removed by boiling. When this is the case, it is usually caused by the presence of calcium sulfate and/or magnesium sulfates in the water, which do not precipitate out as the temperature increases.

can hard water be converted to soft water how can
Ask: can hard water be converted to soft water how can this be done if this is possible?
Answer:
Yes, it is possible for the hard water to be converted to soft water by using vinegar or baking soda. Vinegar is acidic, and baking soda is alkaline. You can use either of the two for converting the hard water into soft water. Both baking soda and vinegar remove the scaly buildup, which is caused by the minerals present in hard water. It is advised that you use distilled white vinegar.
