How is calcium hydrogencarbonate formed?
Tricalcium citrate and water
What other substances cause permanent hardness?
Temporary hardness of water is due to the presence of calcium hydrogentrioxocarbonate(IV) which decompose on heating.when this water is heated calcium trioxocarbonate(iv) is form as insoluble and this brings the ca+ out of the solution as precipitate.once the ca+ re out of the solution soap can now lather well.
Is water hard when temporary hard water was boiled filtered and added with soap solution?
NoBoiling makes temporary hard water become soft water. Temporary hard water contains the compound calcium hydrogencarbonate. When temporary hard water is heated it breaks down to form insoluble calcium carbonate. This is the white scale, or fur you see on the inside of kettles. Using heat to break down a substance is called thermal decomposition.All the calcium hydrogencarbonate has been removed from the water, so it is now soft water. A word equation for the thermal decomposition of temporary hard water is:calcium hydrogencarbonate = calcium carbonate + carbon dioxide + water
What is the name of the compound oxygen and calcium form?
The compound that contains only these two elements is calcium oxide.
What elements are combine to form NaCCa?
Na is Sodium, C is Carbon, and Ca is Calcium
How is calcium hydrogencarbonate formed?
Tricalcium citrate and water
What causes temporary hard water?
calcium hydrogencarbonate.
Is calcium hydrogencarbonate insoluble or soluble in water?
soluble
What is the chemical formula for calcium hydrogencarbonate?
Formula: Ca(HCO3)2
How many different elements are there in sodium hydrogencarbonate?
2
Which elements combine to form calcium chloride?
Calcium (Ca) and Chlorine (Cl).
What makes rainwater able to dissolve carbonate rocks?
A compound called calcium hydrogencarbonate is the main cause of hard water. It forms when rain falls on limestone and chalk rocks. These rocks are made of calcium carbonate, which is insoluble in water. Because rain water contains carbon dioxide, dissolved from the air, this makes it acidic. The rain water reacts with the rocks to form calcium hydrogencarbonate which is soluble. This is the white solid that ends up in our kettles. An equation for the reaction is: water + carbon dioxide + calcium carbonate = calcium hydrogencarbonate H2O (l) + CO2 (g) + CaCO3 (s) = Ca(HCO3)2 (aq)
Is hydrogencarbonate a compound or a element?
Niether. Hydrogencarbonate is an ion. It does not exist on its own, but must be combined with a positive ion to form a compound.
Can calcium and sulfur form a compound?
Yes; these elements can form an ionic compound named calcium sulfide, with formula CaS.

Which of these elements is not a diatomic nitrogen bromine oxygen calcium?
Calcium, alone among the elements listed, does not form a diatomic molecule with another atom of itself.
