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! :)
Saturated solution of calcium hydroxide is added to a solution of magnesium chloride?
A white precipitate of magnesium hydroxide forms because calcium hydroxide reacts with magnesium chloride to form magnesium hydroxide and calcium chloride. This is a double displacement reaction where ions from the two compounds switch partners.
Is calcium hydroxide covalent or ionic?
Calcium hydroxide is an ionic compound. It is made up of a calcium ion (Ca2+) and two hydroxide ions (OH-), which are held together by ionic bonds resulting from the transfer of electrons from calcium to hydroxide.
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 are two products made from calcium compounds?
Two products made from calcium compounds are chalk (calcium carbonate) and cement (calcium oxide).

In what ratio do calcium and hydroxide ions combine?
Calcium and hydroxide ions combine in a 1:2 ratio, where one calcium ion (Ca^2+) combines with two hydroxide ions (OH^-) to form calcium hydroxide (Ca(OH)2).
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.
Name two compounds which can be decomposed by heating them in a Bunsen burner?
Two compounds that can be decomposed by heating them in a Bunsen burner are calcium carbonate (CaCO3), which decomposes into calcium oxide (CaO) and carbon dioxide (CO2), and copper(II) carbonate (CuCO3), which decomposes into copper(II) oxide (CuO) and carbon dioxide (CO2).
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 two products made from calcium compounds?
Two products made from calcium compounds are chalk (calcium carbonate) and cement (calcium oxide).
What will happen if ammonium nitrate and calcium hydroxide is added at the same time?
When ammonium nitrate and calcium hydroxide are added at the same time, they will react to form ammonium nitrate and calcium nitrate along with water. This reaction is an example of a double displacement reaction where the cations of the two compounds switch places.
Is calcium hydroxide made of binary compound?
No, a binary ionic compound is composed of two elements in which one is a negatively charged ion, and the other a positively charged ion. Examples include the following: NaCl, LiF, MgO, MgCl2, K2O
What is the equation for the reaction calcium nitrate and sodium hydroxide which produces calcium hydroxide and sodium nitrate?
The balanced chemical equation for the reaction is: Ca(NO3)2 + 2NaOH -> Ca(OH)2 + 2NaNO3. This equation shows that one molecule of calcium nitrate reacts with two molecules of sodium hydroxide to produce one molecule of calcium hydroxide and two molecules of sodium nitrate.
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 .
