What are the two reactions used to make calcium hydroxide from limestone?
Firstly, the limestone is heated to produce quicklime (calcium oxide - CaO) and carbon dioxide (CO2). The a small amount of water (H2O) is added to the quicklime, to produce slaked lime (calcium hydroxide - Ca(OH)2). In conclusion: limestone quicklime + carbon dioxide quicklime + water → slaked lime I really hope that helped! :)
Does hydroxide have valency?
Yes, hydroxide has a valency of 1. So sodium hydroxide - NaOH - is a compound with Na having a valency of 1 and hydroxide having a valency of 1. For calcium hydroxide, in which calcium (Ca) has a valency of two (2), the formula is Ca(OH)2.
What two compounds make magnesium sulphate?
Many combinations of compounds could make magnesium sulfate:magnesium hydroxide and sulfuric acidmagnesium oxide and sulfuric acidmagnesium hydroxide and sulfur trioxideetc.
What formula correctly represents the compound calcium hydroxide?
Calcium hydroxide formula is 'Ca(OH)2' Note the use of brackets, which indicate that there are two hydroxide anions in the formula. NNB CaOH2 is incorrect, because this indicates only two hydrogen atoms and one oxygen atom .
What are two products made from calcium compounds?
Chalk, cement
Name two compounds which can be decomposed by heating them in a Bunsen burner?
Two examples are: sodium carbonate and calcium hydroxide.
What gas is produced when potassium hydroxide and calcium carbonate are mixed?
Those two compounds do NOT react at all.
What happens when ammonium hydroxide decomposes?
When ammonium hydroxide decomposes, its ions are changed into two compounds. These two compounds are the same that ammonium hydroxide is formed from. Thus, ammonium hydroxide decomposes into water and ammonia.
What are the compounds in calcium carbonate and magnesium hydroxide?
There are NO compounds IN CaCO3 and Mg(OH)2, they are two different compounds by themselves. Each compound is built up of two ore more differentelements, so in CaCO3 are calcium, carbon and oxygen (3x) and in Mg(OH)2 are magnesium (1x), oxygen and hydrogen (both 2x).
What are the products made when calcium reacts with water?
There are actually two products made.When Calcium reacts with water, Calcium Hydroxide is produced and so is Hydrogen. So, both Calcium Hydroxide and Hydrogen are produced, looking like this in a word equation:Calcium + Water = Calcium Hydroxide + Hydrogen

What is the chemical balance formula for Ca(oh)2?
The chemical formula for calcium hydroxide is Ca(OH)2. It consists of one calcium ion (Ca2+) and two hydroxide ions (OH-). The balance of charges is achieved by the two negative charges from the hydroxide ions balancing the positive charge from the calcium ion.
Does calcium carbonate contain calcium acetate?
No. Calcium carbonate and calcium acetate are two different compounds.
What two compounds have the same radical?
For example sodium hydroxide ant caesium hydroxide: NaOH, CsOH.
Does hydroxide have valency?
Yes, hydroxide has a valency of 1. So sodium hydroxide - NaOH - is a compound with Na having a valency of 1 and hydroxide having a valency of 1. For calcium hydroxide, in which calcium (Ca) has a valency of two (2), the formula is Ca(OH)2.
What is calcium or compounds of calcium used for?
Calcium is an element, located in group two of the Periodic Table.
What two compounds make magnesium sulphate?
Many combinations of compounds could make magnesium sulfate:magnesium hydroxide and sulfuric acidmagnesium oxide and sulfuric acidmagnesium hydroxide and sulfur trioxideetc.
