Question

hard water,softwater,heavywater​

Answer 1

HARD WATER : Hard water is water that has high mineral content. Hard water is formed when water percolates through deposits of limestone and chalk which are largely made up of calcium and magnesium carbonates

SOFT WATER: Soft water is surface water that contains low concentrations of ions and in particular is low in ions of calcium and magnesium. Soft water naturally occurs where rainfall and the drainage basin of rivers are formed of hard, impervious and calcium-poor rocks.

HEAVY WATER: water in which the hydrogen in the molecules is partly or wholly replaced by the isotope deuterium, used especially as a moderator in nuclear reactors.

Answer 2

Hey mate......
Here is your answer........

$\huge{\bold{\red{Hard\: Water}}}$

Hard water... is water that contains an appreciable quantity of dissolved minerals (like calcium and magnesium). 

$\huge{\bold{\red{Soft\:Water}}}$

Soft water... is treatedwater in which the only ion is sodium. As rainwater falls, it is naturally soft. ... On the other hand, soft water tastes salty and is sometimes not suitable for drinking.


$\huge{\bold{\red{Heavy\:Water}}}$

water in which the hydrogen in the molecules is partly or wholly replaced by the isotope deuterium, used especially as a moderator in nuclear reactors.



I HOPE THIS IS A HELPFUL ANSWER.....☺✌☺
