Question

Ca(OH)2 +__________=Ca(NO3)2 Пожалуйста!!!

Answer 1

Ca(OH)2 + 2HNO3 => Ca(NO3)2 + 2H2O

 кстати, я бы НЕ использовала N2O5  это ОЧЕНЬ хитрый оксид ...и его в принципе не существует 

Answer 2

Ca(OH)2 + N2O5 = Ca(NO3)2 + H2O

Answer 3

The balanced chemical equation for the reaction between Ca(OH)2 (calcium hydroxide) and Ca(NO3)2 (calcium nitrate) can be written as:

Ca(OH)2 + 2 HNO3 → Ca(NO3)2 + 2 H2O

In this equation, calcium hydroxide reacts with nitric acid (HNO3) to form calcium nitrate and water. The balanced equation shows that you need 2 moles of nitric acid for every 1 mole of calcium hydroxide to obtain 1 mole of calcium nitrate and 2 moles of water.
