What is the balanced equation for CaCO3 Cao(s0 plus CO2(g)?
The equation is:CaCO3.......................→CaO + CO2
What happens when CaO dissolves in water?
this creats a base compound H2O+CaO-->H2CaO2 - Wrong. Correction; CaO(s) + H2O(l) ---> Ca[OH]2(aq) + heat Calcium hydroxide.
How do you convert between the molar percentage of a compound e.g. CaO and the atomic percentage of the elements e.g. Ca and O?
To convert from the molar percentage of a compound to the atomic percentage of its elements, you can use the molar mass of each element to calculate the number of moles of each element in one mole of the compound. Then, you can use these values to determine the atomic percentage of each element. For example, in CaO, one mole of CaO contains 1 mole of Ca and 1 mole of O. So, the atomic percentage of Ca would be (molar percentage of CaO) * (molar mass of Ca) / (molar mass of CaO), and similarly for O.
When changing from one unit of measurement to another a conversion factor is used to?
The conversion factor is used to made this conversion.
How many valence electrons are in CaO?
Calcium oxide (CaO) consists of calcium (Ca) and oxygen (O). Calcium, a group 2 element, has 2 valence electrons, while oxygen, a group 16 element, has 6 valence electrons. Therefore, in total, CaO has 2 (from Ca) + 6 (from O) = 8 valence electrons.
How does Ca react with O?
CaO
What is the percent composition of CA in CaO?
40 g / 56 g X 100%
What is wrong with the equation CaO O gives CaO?
Ca + O2 gives 2CaO
What is the balanced equation for calcium hydroxide yields calcium oxide and water?
The balanced equation for this reaction is: Ca(OH)2 --> CaO + H2O.
What is the balanced equation for the addition water to quicklime?
The balanced equation for the addition of water to quicklime, which is calcium oxide (CaO), is: CaO + H2O → Ca(OH)2.
What is the balanced equation for CaCO3 Cao(s0 plus CO2(g)?
The equation is:CaCO3.......................→CaO + CO2
If H2O plus CaO H2CaO2 a base then what is another equasion for making a base with CaO?
CaO + H2O → Ca(OH)2 + HEAT
What is the percent composition of calcium (Ca) in (CaO)?
40 g / 56 g X 100%
What is lime meant by slaked?
It is the process of converting CaO to Ca(OH)2 by adding the CaO into water. The reaction is: CaO+H2O ---> Ca(OH)2 This reaction is highly exothermic and releases large amount of heat (63.7 kJoules for 1 mol of CaO used).
Which of the following are not decomposition reactions?
2Mg + O2 → 2MgO CaO + H2O → Ca(OH)2
What is the balanced symbol equation for calcium oxide with water goes to hydroxide?
The balanced symbol equation for calcium oxide (CaO) with water (H2O) forming calcium hydroxide (Ca(OH)2) is: CaO + H2O → Ca(OH)2
How many atoms are there in CaO?
Two atoms. One calcium (Ca) and one oxygen (O).
