Question

Ca+CaO +CaCl2->Ca(OH)2

Answer 1

2Ca + O2 = 2CaO

CaO + 2HCl = CaCl2 + H2O

CaCl2 + Ba(OH)2 = BaCl2 + Ca(OH)2

Answer 2

The chemical equation you provided seems to be incomplete, as it does not show the full reaction. Additionally, it appears to have some errors. I'll try to complete and correct it for you:

Ca + CaO + CaCl2 -> Ca(OH)2

This equation shows a reaction between calcium (Ca), calcium oxide (CaO), and calcium chloride (CaCl2) resulting in the formation of calcium hydroxide (Ca(OH)2).

However, the equation is not balanced. Let's balance it to ensure that the same number of atoms of each element are present on both sides of the equation:

Ca + CaO + CaCl2 -> Ca(OH)2

To balance the equation, we need to ensure that the number of each type of atom is the same on both sides. Here's the balanced equation:

3Ca + CaO + 2CaCl2 -> Ca(OH)2

In this balanced equation, three moles of calcium (Ca) react with one mole of calcium oxide (CaO) and two moles of calcium chloride (CaCl2) to produce one mole of calcium hydroxide (Ca(OH)2).
