If you are doing PF then it's KOH + H2SO4 � KHSO4 + H2O APEX- 2ca(s)+o2(g) --> 2cao(s)
Burning, oxidation.
2NH4NO3->2N2+O2+4H2O
combustion
2NaH2 + O2 yields 2Na + 2H2O
The balanced equation for the reaction between calcium and oxygen to produce calcium oxide is: 2Ca + O2 -> 2CaO
2Ca(s) + O2(g) -> 2CaO(s)
The symbol equation for the formation of calcium oxide is: Ca + O2 -> CaO.
Ca + O2 gives 2CaO
The balanced equation for calcium reacting with oxygen gas is: 2Ca + O2 -> 2CaO.
The equation is:CaCO3.......................→CaO + CO2
Calcium (Ca) is element. O2 and CaO are molecules.
The reaction between calcium metal and oxygen gas is a chemical reaction that results in the formation of solid calcium oxide. This reaction is represented by the chemical equation: 2Ca(s) + O2(g) -> 2CaO(s)
0,092 moles CaO
For the reaction 2Ca + O2 → 2CaO, the stoichiometry is 1 mol O2 reacts with 2 mol Ca. So, if 0.016 mol of O2 reacts, it will require half that amount of Ca, which is 0.008 mol. Therefore, 0.008 mol of the product CaO will form.
The oxidation of calcium can be represented by the equation: 2Ca(s) + O2(g) -> 2CaO(s). This reaction involves the combination of calcium metal with oxygen gas to form calcium oxide.
Calcium, Ca, and oxygen, O2, are elements (first is mono-atomic, the second is diatomic). Calcium oxide, CaO, is a molecule made of two elements.
