Is pencil considered hard or brittle?
hard
Does drinking hard water cause gout?
Water intake can reduce the uric acid concentration in the blood by transporting it out of the body via the kidney and other organs as well as making the blood more capable of holding more acid before it crystallizes.
Is there a chemical way to remove a calcium ring on a pebble tec salt water pool?
Yes, there is a chemical. As long as you clean the tile while the calcium is just a film. Use "Biodex 300" follow the instructions carefully to avoid injury.Once the calcium or hard water deposit has become thick it must be removed profesionally. There are many debates about what method should be used, as some may cause dammage to the tile. The use of Biodex 300 can stain the substrate. I have been a professional pool tile cleaner for many years. The absolute safest way to remove the calcium is to dry soda blast it.
How do you get hard clay to become soft?
Add water. If you can, poke holes in it so the water can really soak. Wrapping it in a plastic bag will also prevent it from hardening so quickly.
How do rapids form?
Rapids form when there is hard rock and soft rock together. The water goes over the hard rock and then cuts through the soft rock. This makes a bump where the hard rock is and when the water goes over it the water is going to go up with the bump. These can make pot holes sometimes.
Is Water with a high calcium content is considered to be hard.?
Yes, is correct.
Why does water become hard?
Some water is called ''hard'' water because, of all the deposits in the water.
Is calcium found in hard water?
YES, it's is the calcium that makes the water "hard". That is why you use a cleaner that has a calcium remover in it to get those hard water stains off.
What by product is linked to hard water?
Calcium and iron deposits within the water are harmless and often colorless unless the iron content is large (think rust color). These two elements are creators of 'hard water'.
Two elements found in hard water?
Typicall water hardness is caused from calcium and magnesium compounds dissolved in the water. The term "hard water" is used to describe water that has a high mineral content, usually calcium and magnesium in the form of carbonates, but may include several other metals as well as bicarbonates and sulfates, (water with a low mineral content is known as soft water). A high enough concentration of these metals in your water can cause white lime scales on surfaces which the water comes into contact with. Total water 'hardness' is reported as ppm w/v (or mg/L) of calcium carbonate (CaCO3). Water hardness usually measures the total concentration of calcium and magnesium, the two most common metal ions, although in some locations around the world iron, aluminium, and manganese may also be present at elevated levels. Calcium usually enters the water as either calcium carbonate (CaCO3), from limestone or chalk, or from mineral deposits of calcium sulfate (CaSO4).
Why is the bone in our bodt hard?
High mineral content (calcium salts).
What is the chemical in hard water?
Forms of Calcium is what makes hard water hard
What is the hardness in the water?
Forms of Calcium is what makes hard water hard
What forms hard water?
Hard water contain calcium and magenesium carbonates.
What causes 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.
What is the difference between hard water and soft water?
The presence of calcium and magnesium salts in the form of hydrogencarbonate, chloride and sulphate in water makes water 'hard'. Hard water does not give lather with soap. Whereas, water free from souluble salts of calcium and magnesium is called soft water. It gives lather with soap. And also hard water forms scum(precipitate) with soap, therefore unsutable for laundry but soft water does not form scum.
Why is soap soluble in the presence of sodium ions but not calcium ions?
Nearly all sodium salts are soluble in water. Most calcium salts aren't. calcium salts of the same fatty acids that make up potassium and sodium soaps are not water soluble. Dissolved calcium and magnesium are the two most common minerals that make water "hard." The degree of hardness becomes greater as the calcium and magnesium content increases. Bathing with soap in hard water leaves a film of sticky soap curd on the skin
