Mineral deposits.
The calcium (as calcium carbonate) in hard water replaces the sodium on the fatty acids of the soap causing them to precipitate as a sticky scum. This deposits soap scum on the things being washed and causes the formation of "bathtub ring" on bathtubs, sinks, etc.
No. Hard water is water with high amounts of dissolved calcium and magnesium.
Hard water is produced when water passes through rocks and soil that contain high levels of minerals such as calcium and magnesium. These minerals dissolve into the water, making it "hard" by causing issues such as soap scum buildup and reduced lathering of soaps and detergents.
Hard water contain calcium bicarbonate, magnesium bicarbonate in temporary hard water and calcium/magnesium sulfate in permanent hard water. Soft water contain doesn't contain these substances or only in very limited concentations.
Hard water is the one that does not lather with soap. Permanent hard water can be converted to soft water by adding sodium carbonate (Na2CO3), or calgon or zeolite.
Hard water.
Dissolved minerals in the water. In most cases it is better to water your garden with hard water instead of treated water. The plants typically like the minerals found in hard water.
calcium hydrogencarbonate.
That is very hard to say. There are 5-8 oases on the upper inland plains of Oman, but the water is artesian and seasonal. Sometimes there is enough for animals to drink, but more often just mud.
Your incoming fill water may be hard.

what do u think im not an expert
Manhattan and all New York City supplied water comes from reservoirs filled by rain water and is considered soft. Hard water contains minerals such as calcium and magnesium carbonates usually leached by water percolating (moving through) underground limestone and chalk deposits and retrieved from wells.
River water is generally considered soft water because it contains low levels of minerals like calcium and magnesium. Hard water typically comes from sources like groundwater or wells, where it has passed through mineral-rich rocks.
When water comes into contact with gum, it causes the gum to lose its elasticity and become hard. This is because water disrupts the molecular structure of the gum, making it less flexible and more rigid.
it is friction and when the water goes on the brakes and tires they bond together
being a stupid person in the water trying to act hard lol x
