Question

how many moles of H2O will be produced from 12.3 moles of HCI reacting with Ca(OH)2

Answer 1

Decision:

2mol 2mol                                                                               

2HCL + Ca (OH)   ₂   = CaCL   ₂   + 2H   ₂   O

12,3mol х

х = 12,3 * 2/2

x = 12,3mol (H   ₂   O)

Answer:

12,3 mol (H   ₂   O)
