Question

When 33 g of CaO and 10 g of H2O react, how many grams of calcium hydroxide would you expect to be produced* Explain your answer.

Answer 1

Answer:

Calculate the number of moles of oxygen required to react exactly with 4.30 ... How many moles of NH3 can be made from 2.00 moles of Nz if you have excess Hz? ... 10. How many grams of water are made when 3.00 moles of butanol is combusted? ... If 50.0 g of calcium oxide were produced, how many grams of calcium ...

Answer 2

Answer:

41.44 g

Explanation:

First of all, we must put down the equation of the reaction;

$CaO + H2O ----->Ca(OH)2$

Number of moles of CaO = 33g/56 g/mol = 0.59 moles

Number of moles of H20 = 10g/18 g/mol = 0.56 moles

Since the reaction is in 1:1 mole ration, H2O is the limiting reactant

Hence;

mass of Ca(OH)2 produced = 0.56 moles * 74 g/mol = 41.44 g
