The three disadvantages of hard water are:
1. Hard water is unsuitable for washing because soap does not readily create a lather in it.
2. Soap may react and produce, wasting the soap.
3. Due to the development of calcium and magnesium carbonates, tea kettles will get furred.
<h3>Hard water</h3>
Water that contains a lot of minerals is referred to as hard water. In limestone, chalk, or gypsum deposits, which are mostly composed of calcium and magnesium carbonates, bicarbonates, and sulphates, hard water is created as a result of percolation. A moderate health advantage from drinking hard water is possible. In industrial settings where water hardness is regulated to prevent expensive breakdowns in boilers, cooling towers, and other water-handling equipment, it can present serious issues. Hard water is frequently detected in home settings by the build-up of lime scale in kettles and water heaters as well as by the absence of foam when soap is agitated in water. Wherever there is a worry about water hardness, water softening is frequently employed to lessen the negative impacts of hard water.

<h3>The following compound is CH3 CH3 CH2 CH2 CH2 CH3, but what is its IUPAC name?</h3>
Answer and justification A longest carbon chain in the above diagram has seven carbon atoms, as can be observed.The IUPAC nomenclature for this compound is heptane since all of the bonds are single bonds devoid of any functional groups.
<h3>What is this compound's IUPAC name, CH3 CH2 CH2 CH2 CH2 CH?</h3>
When there are nine carbons, the word non is the root.Therefore, nonane is the IUPAC term for CH3-CH2-CH2-CH2-CH2-CH2-CH2-CH3.

#SPJ4
Atoms of one element are converted to atoms of another element through transmutation or nuclear transmutation.
Answer:
HCL being a strong electrolyte dissociates in water to give H+ and Cl- ions. KMnO4 being a strong oxidising agent oxidises Chloride ion(Cl-) to Cl2. ... Hence more amount of KMnO4 is usedup which results in error in reading. The situation is completely the opposite with K2Cr2O7.
