The mass of 7,346 moles of Ca(OH)2 is 544,3 g.
2 moles of Ca and 4 moles of OH
12.97
CaOH2 is a base because calcium is compounded with hydroxide, rather than hydrogen. Most if not all acids' names begin with 'H', while most if not all bases' names end with 'OH'.
Limestone can be helpful in many way, it depends on what state it is in and the uses can vary. As solid limestone or crushed limestone, it can be used by extracting iron from it's ore, to make sodium carbonate, used in road contruction or to make concrete. As CaO (heated limestone), the uses are making steel Fromm iron, to neutrilize acidic soil or it can be a drying agent. CaOH2 (calcium hydroxide or slaked lime - lime stone when it's wetted) neutralises acidic soil. I got this info from my chemistry book :-d
CaCl2 and H2O
CaO + H2O -> Ca(OH)2 If you are in doubt about this then count the number of atoms of each element on each side of the equation to verify that they correspond.

Al2SO43 CaOH2 - AlOH3 CaSO4. B. H3BO3 - H4B6O11 H2O C. NaOH Cl2 - NaCl NaClO H2O. D. Al O2- Al2O3. E. PCl5 H2O - HCl H3PO" is a 8.9 balanced equation Al2SO43 CaOH2 - AlOH3 CaSO4. B. H3BO3 - H4B6O11 H2O C. NaOH Cl2 - NaCl NaClO H2O. D. Al O2- Al2O3. E. PCl5 H2O - HCl H3PO" is a 8.9 balanced equation
2HCl + Ca(OH)2=CaCl2 +2H2O this is hydrochloric acid add ant acid = the symbol equation
Ca(OH)2 + Na2CO3 = CaCO3 + 2 NaOH
Ca(OH)2(aq) + HNO3(aq) --> H2O(l) + Ca2+ (aq)+ NO3- (aq) Volume of Ca(OH)2 = 22.0mL = 0.022L Volume of HNO3 = 40.0 = 0.04L Molarity = moles of solute/Volume of solution M = .06/0.062 = 0.9677 M of Ca(OH)2
Nope... it is not.
Calcium Hydroxide, or CaOH2, is a base. Generally compounds containing hydroxyl groups and metals will act as bases in reaction.
You will need water for the reaction to take place. CO2(g)+H2O(l)--> H2CO3(aq) NOW IT IS BALANCED CaOH2(s)+H2CO3(aq) --> CaCO3(s)+2H2O(l)
